Then set each receiver low, read it, then set high and cycle through that way. This may overcome some issues with it slowing down, but probably not all issues as they still transmit on the same frequency. Hopefully using the high power antenna on the receiver will fix the problem. *** can’t seem to combine the small green chips with the large antenna-based ones to get them to talk together. That sucks….. · Doesn’t seem to work with Samd21mini. May be a library issue. Have had it working with Teensy 3.6 and 3.2 in the past though. · Maybe something in this post about using multiple nrf24’s via SI https://forum.arduino.cc/index.php?topic=435717.0 REMEMBER that they can send 32 bytes per packet without really affecting speed – and if you have 2 of them talking to one receiver they can often clash with each other if you are sending data really quickly. So the best way to send high frequency data is to have a single receiver for each transmitter. The next best way is to create arrays of the data on the transmitter and send it when they are 32 bytes long. That allows up to 16 different 16-bit unsigned integers to be put in an array and sent in a burst. This reduces the chances of lost packets dramatically. My latest working examples of this are: RF24_exampleMULTI_BATCH_B1 RF24_exampleMULTI_BATCH_B2 RF24_exampleMULTI_Receiver_BATCH OSV System Currently has way too many parts, so use an Arduino with integrated charge circuit and Bluetooth.

You need to first set it up in a softwareserial format to change the AT commands. Use this guide AND YOU MUST connect the key pin. Just slide a jumper cable into the EN pinhole, it will do fine. http://www.instructables.com/id/Modify-The-HC-05-Bluetooth-Module-Defaults-Using-A/ Most likely using it on a 3.3V system in the end, so make sure to include a voltage divider as per below. Easy as, just have one resistor double the capacity of the other so any combo should work: + jumper into pinhole Upload the code to the Arduino to allow you to configure the module, then connect to the Arduino via the USB port connection to run the code – it talks to both the Arduino and the hc-05 using this method. Once the code is run and you set the commands: · To change device name from the default HC-05 to let's say MYBLUE enter: "AT+NAME=MYBLUE" · To change default security code from 1234 to 2987 enter: "AT+PSWD=2987" · To change HC-05 baud rate from default 9600 to 115200, 1 stop bit, 0 parity enter: "AT+UART=115200,1,0" Disconnect the serial window and remove the power supply to the Bluetooth module. Then upload code for doing whatever you want (AS PER NORMAL SERIAL METHOD) to the Arduino using the standard method. Then disconnect the Arduino, connect the HC-05 RX/TX pins to the RX/TX pins of the Arduino and provide power to the Arduino (not via computer). You can then talk directly to the Arduino via the HC-05 as if it were a wired serial port. ***problems when running 3+ Bluetooth at once on same computer in same program. Get around this by having individual programs for each channel, and link them together like I did with Kinect with shared variable to start and stop test. JDY-31 Bluetooth Module Banggood Might be some info here http://www.martyncurrey.com/bluetooth-modules/ ***These JDY chips are AWESOME!!!!! FAR better than the HC chips. So cheap and easy. The only trick is when trying to change baud rate etc. For step by step: 1. Hook them up to an Arduino STATE: N/C RX: Arduino RX (yup - you actually don't do an RX/TX crossover to the Arduino when sending AT commands to the module) TX: Arduino TX GND: Arduino GND VCC: Arduino 3.3V 2. Open the Arduino IDE serial monitor. MAKE SURE THAT YOU ARE USING THE SERIAL PORT FOR THE ARDUINO – NOT THE BLUETOOTH CHIP. IT TALKS VIA THE ARDUINO COM PORT. Set the serial monitor to 9600 baud and "Both NL and CR" - Type "AT+VERSION" into the input text box at the top of the serial monitor and hit the "Send" button. You should see this response in the serial monitor: +VERSION=JDY-31-V1.34,Bluetooth V3.0 – 3. To change baud rate, type AT+BAUD8 to change to 115200 QDUINO MINI May need to connect to usb2.0 port to upload data. Can be finicky. ***IMPORTANT!!!!**** To use with serial port must use Serial1.begin instead of Serial.begin. Massive pain in the arse and won’t work if you forget. **Can’t run the mpu9250 on the qduino, it seems to brick the bloody thing. Lost 3 qduinos trying to do it. **May be better of using the Adafruit M0 feather range with prototype board.

These are simple to setup, just connect to the ftdi cable, open the serial port for the ftdi cable and set the baud rate to 9600. Then type in the following commands to change the settings: To change name: AT+NAME=ROSS To change baud rate: AT+UART=115200,1,0 **to note – sometimes I cannot use the HC-06 with SPI interface hardware. The Bluesmirf from sparkfun works though. Buggered if I know why. **remember that Bluetooth with Arduino works much better than on a windows pc LIDAR Use the I2C method – no reason to use PWM and I2C has more options and is easy to wire (no resistor).

Might work ///////////SCREW THIS NEXT PART!!! Best to use the python node when you can, much better /* OLD – IGNORE UNLESS NODE DOES NOT WORK Can be quite difficult to run libraries etc through Python in Labview. What seems to work is: 1. Install all libraries etc. in Python on the computer (important for server). Best to do this after the Labview and Python install, then use the PIP install XXX command line method shown here https://www.youtube.com/watch?v=YWn8Wj69Dm4 I used matplotlib, statsmodels, numpy, scipy, statistics : pip install 2. Load the .py file as a text file in Labview, then change the string to update the data (i.e. put the array numbers in that way). Save the .py file, making sure to use “return” for the variable that you want to send back to labview. 3. Labview and python must be the same bitness (eg. 32-bit labview with 32-bit python). This example runs a shapiro wilk test on data, which I update in Labview: /////// from scipy.stats import shapiro def Shapiro(data): data = [1,2,3,4,5,5,5,5,5,6,5,4,3,2,1] stat, p = shapiro(data) return p; ////// 4. Use the Labview python integration vi’s to read back the return value. ****Found that arrays are tricky to send from labview, so better off just building the .py file in labview and putting the data in that way (broken wire in pic is array of data), saving it to the computer, then running the python integrator to just pull the result.

Best bet is to just create a python script then run it use system exec command line.

Then set each receiver low, read it, then set high and cycle through that way. This may overcome some issues with it slowing down, but probably not all issues as they still transmit on the same frequency. Hopefully using the high power antenna on the receiver will fix the problem. *** can’t seem to combine the small green chips with the large antenna-based ones to get them to talk together. That sucks….. · Doesn’t seem to work with Samd21mini. May be a library issue. Have had it working with Teensy 3.6 and 3.2 in the past though. · Maybe something in this post about using multiple nrf24’s via SI https://forum.arduino.cc/index.php?topic=435717.0 REMEMBER that they can send 32 bytes per packet without really affecting speed – and if you have 2 of them talking to one receiver they can often clash with each other if you are sending data really quickly. So the best way to send high frequency data is to have a single receiver for each transmitter. The next best way is to create arrays of the data on the transmitter and send it when they are 32 bytes long. That allows up to 16 different 16-bit unsigned integers to be put in an array and sent in a burst. This reduces the chances of lost packets dramatically. My latest working examples of this are: RF24_exampleMULTI_BATCH_B1 RF24_exampleMULTI_BATCH_B2 RF24_exampleMULTI_Receiver_BATCH OSV System Currently has way too many parts, so use an Arduino with integrated charge circuit and Bluetooth.

You need to first set it up in a softwareserial format to change the AT commands. Use this guide AND YOU MUST connect the key pin. Just slide a jumper cable into the EN pinhole, it will do fine. http://www.instructables.com/id/Modify-The-HC-05-Bluetooth-Module-Defaults-Using-A/ Most likely using it on a 3.3V system in the end, so make sure to include a voltage divider as per below. Easy as, just have one resistor double the capacity of the other so any combo should work: + jumper into pinhole Upload the code to the Arduino to allow you to configure the module, then connect to the Arduino via the USB port connection to run the code – it talks to both the Arduino and the hc-05 using this method. Once the code is run and you set the commands: · To change device name from the default HC-05 to let's say MYBLUE enter: "AT+NAME=MYBLUE" · To change default security code from 1234 to 2987 enter: "AT+PSWD=2987" · To change HC-05 baud rate from default 9600 to 115200, 1 stop bit, 0 parity enter: "AT+UART=115200,1,0" Disconnect the serial window and remove the power supply to the Bluetooth module. Then upload code for doing whatever you want (AS PER NORMAL SERIAL METHOD) to the Arduino using the standard method. Then disconnect the Arduino, connect the HC-05 RX/TX pins to the RX/TX pins of the Arduino and provide power to the Arduino (not via computer). You can then talk directly to the Arduino via the HC-05 as if it were a wired serial port. ***problems when running 3+ Bluetooth at once on same computer in same program.

JDY-31 Bluetooth Module Banggood Might be some info here http://www.martyncurrey.com/bluetooth-modules/ ***These JDY chips are AWESOME!!!!! FAR better than the HC chips. So cheap and easy. The only trick is when trying to change baud rate etc. For step by step: 1. Hook them up to an Arduino STATE: N/C RX: Arduino RX (yup - you actually don't do an RX/TX crossover to the Arduino when sending AT commands to the module) TX: Arduino TX GND: Arduino GND VCC: Arduino 3.3V 2. Open the Arduino IDE serial monitor. MAKE SURE THAT YOU ARE USING THE SERIAL PORT FOR THE ARDUINO – NOT THE BLUETOOTH CHIP. IT TALKS VIA THE ARDUINO COM PORT. Set the serial monitor to 9600 baud and "Both NL and CR" - Type "AT+VERSION" into the input text box at the top of the serial monitor and hit the "Send" button. You should see this response in the serial monitor: +VERSION=JDY-31-V1.34,Bluetooth V3.0 – 3. To change baud rate, type AT+BAUD8 to change to 115200 QDUINO MINI May need to connect to usb2.0 port to upload data. Can be finicky. ***IMPORTANT!!!!**** To use with serial port must use Serial1.begin instead of Serial.begin. Massive pain in the arse and won’t work if you forget. **Can’t run the mpu9250 on the qduino, it seems to brick the bloody thing. Lost 3 qduinos trying to do it. **May be better of using the Adafruit M0 feather range with prototype board.

These are simple to setup, just connect to the ftdi cable, open the serial port for the ftdi cable and set the baud rate to 9600. Then type in the following commands to change the settings: To change name: AT+NAME=ROSS To change baud rate: AT+UART=115200,1,0 **to note – sometimes I cannot use the HC-06 with SPI interface hardware. The Bluesmirf from sparkfun works though. Buggered if I know why. **remember that Bluetooth with Arduino works much better than on a windows pc LIDAR Use the I2C method – no reason to use PWM and I2C has more options and is easy to wire (no resistor).

Not sure if it is the python stuff though as even with that in the block diagram but set to false in a case structure still had some issues. Need to play with this…. The trick to using the python node is making sure that the input data you set is the same as the output data. This can be tricky. Check these examples: Consider reformatting data in python so that it fits the output styles labview allows. https://stackoverflow.com/questions/41792463/how-to-convert-a-list-of-list-to-array-in-python doing ANOVA? http://www.pybloggers.com/2018/10/repeated-measures-anova-in-python-using-statsmodels/ https://github.com/mathang/jupyter/tree/master/Python_ANOVA and use the list to array method above. Might work ///////////SCREW THIS NEXT PART!!! Best to use the python node when you can, much better /* OLD – IGNORE UNLESS NODE DOES NOT WORK Can be quite difficult to run libraries etc through Python in Labview. What seems to work is: 1. Install all libraries etc. in Python on the computer (important for server). Best to do this after the Labview and Python install, then use the PIP install XXX command line method shown here https://www.youtube.com/watch?v=YWn8Wj69Dm4 I used matplotlib, statsmodels, numpy, scipy, statistics : pip install 2. Load the .py file as a text file in Labview, then change the string to update the data (i.e. put the array numbers in that way). Save the .py file, making sure to use “return” for the variable that you want to send back to labview. 3. Labview and python must be the same bitness (eg. 32-bit labview with 32-bit python). This example runs a shapiro wilk test on data, which I update in Labview: /////// from scipy.stats import shapiro def Shapiro(data): data = [1,2,3,4,5,5,5,5,5,6,5,4,3,2,1] stat, p = shapiro(data) return p; ////// 4. Use the Labview python integration vi’s to read back the return value. ****Found that arrays are tricky to send from labview, so better off just building the .py file in labview and putting the data in that way (broken wire in pic is array of data), saving it to the computer, then running the python integrator to just pull the result. Works nicely! ****Seems to struggle running any python module via the integrator that do things behind the scenes (eg. save files). Best bet is to just create a python script then run it use system exec command line. This is a little weird as it d oesn’t seem to like running direct command line, need to set the location of python.exe and then set location of the python script to run. As per below (broken wire is just error coming in).pip stats */ If multiple versions of Python make sure to set default version like this: https://www.quora.com/Can-I-have-32-and-64-bit-Python-installed-at-once-Will-there-be-any-issues-I-accidentally-installed-32-bit-a-while-ago-and-I-dont-know-how-to-upgrade-it-without-messing-anything-up ****When calling Python from labview it can be difficult as you need to run it as a function. I’ve had lots of issues with this, so often better off just calling a python script (see the website stats program for an example) from the command line via labview and saving the result to file. Then you load the file and display the result. - When saving text file convert the output to string before saving. Eg: output = levene(*dat) string = str(output) file = open("C:\BUILDS\sample.txt","w") file.write(string) file.close() arduino for gesture recognition https://www.sparkfun.com/products/15580 consider trying this for steps, stair climbing etc. classification. https://github.com/arduino/ArduinoTensorFlowLiteTutorials/blob/master/GestureToEmoji/exercises/exercise8.md circuitpython https://learn.adafruit.com/arduino-to-circuitpython?view=all emg https://masteringelectronicsdesign.com/measure-a-bipolar-signal-with-an-arduino-board/ https://robotacademy.net.au/ You need to look at this!!!!! Shows how to calculate inverse kinematics etc using Peter Corke’s toolboxes https://bookshelf.vitalsource.com/#/books/9781492576334/cfi/62!/4/4@0:0.00 ***This is the research in biomechanics textbook that shows in detail how to calculate all joint angles, forces etc. in gait. Data visualisation: Here’s a list of data viz tools, no highcharts though….. https://blog.capterra.com/free-and-open-source-data-visualization-tools/ HIGHCHARTS Update Data by clicking Here’s a great example of how you can update highcharts graphs by typing a number and clicking add data: http://jsfiddle.net/b4rbjhtq/ This one is great – shows how to update the yaxis range manually by typing in values on the graph. These typed in values don’t show up in the exported graph either so it looks great. http://jsfiddle.net/Wm7ft/ The best flowchart and Gantt chart software. Great for visualising tables etc. https://www.draw.io/ Great book http://www.dspguide.com/ Sankey Flow charts https://www.highcharts.com/docs/chart-and-series-types/sankey-diagram Here’s some examples to take code snippets from: http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/plotoptions/sankey-outgoing This one shows how to change font size, location etc. http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/plotoptions/sankey-inverted/ This one shows how to set colour – important! http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/css/sankey/ This one uses styled mode to change the visible text to whatever you like, and also sets colour. VERY USEFUL!!! Here’s my CONSORT diagram example: C:\HIGHCHARTS\examples\Vertical Sankey CONSORT Diagram.html Use Highcharts with an excel style data input table (handsontable). This is very nice! https://codepen.io/handsoncode/pen/prBejL Statistics: http://www.estimationstats.com/#/ This has some nice example graphs with effect size and distribution plotted with the dot point graph. HOWEVER – the distribution is fake, as it always looks Gaussian. LABVIEW: Playing videos Don’t try to embed them, just use a command line interface to open them in the default media player. This is much better! The command looks like this: cmd /c "C:\Users\Ross\Videos\EMG Setup.mp4" Custom buttons When making buttons with images or GIFs, click Advanced, customise, Operate, change to customise mode, then picture item to choose the false/true condiution for the picture, then Import from file at same size. Sharing Data Between Executables Use shared variables as per the example program. Make sure to setup the build EXACTLY as it is done in that example, and to include shared variable runtime engine in the build. GAIT ANALYSIS BiomechZoo: seems to be able to calculate joint angles and moments from c3d file, replicates the methods of PiG. Can I alter this so it will do whatever I want? Need to go through the code to find out. C:\Users\Ross\Desktop\EQUIPMENT\BiomechZOO https://github.com/PhilD001/biomechZoo/tree/master/Toolbox https://www.sciencedirect.com/science/article/pii/S0169260716304424?via%3Dihub#bib0029 An intriguing python toolkit from the Childrens hospital in Melbourne – appears to be able to calculate kinematics and kinetics from c3d files. Documentation is lacking though. https://pycgm2.github.io/pyCGM2-API-DOC/pyCGM2.html A python library from Cleveland – not sure how much use it is but worth a look: https://gait-analysis-toolkit.readthedocs.io/en/latest/ Scratch Using this to make the games for OSV EMG biofeedback system. Need to convert the scratch code into executables. The best method seems to be this one: https://www.youtube.com/watch?v=bB00qUvH3L0 https://junebeetle.github.io/converter/online/ ***no longer!!!!! Scratch 3.0 allows you to create html files for the games which is GREAT! Simply copy the project id from the browser into the htmlifier and run it and it will create the webpage. Runs quite well, I use the following page and settings. https://sheeptester.github.io/words-go-here/htmlifier/#note-2 To load these as full screen games in chrome, make a copy of chrome shortcut (to chrome itself) for each of the games. Then type this onto the end of the target in the properties tab of the shortcut --start-fullscreen --allow-file-access-from-files file:///C:/A.html If the file is called A.html SGH equipment: 1. EMG system: 3 x Bluetooth HC05 (have) OR 6 x rf24L (have – can I use antenna versions with non-antenna?) 3 x qduino (need to get) 3 x lipo batteries (??? Get more) 3 x myoware (get more) 2. LIDAR systems 2 x lidars (have expensive ones Lidar Lite V3) 2 x Arduino to run them (should provide 5V power to LIDAR at 140ma – but have run at 3.3V no problem form tinyduino so not sure of that….) **with weigh scales need to have hx711 amplifiers – have a few of them lying around. Custom HHD with two IMU build - The IMU on the hand held dyno uses the Y angle. Doesn’t seem to need any correction for Euler angle issues. - IMU on shin uses Y as well – but does need correct. If Z angle is below -100 negate the Y angle, if above -100 then keep as is. - Com ports 37 (hhd imu), 29 (load cell), 21 (ankle) Online quiz creation https://freeonlinesurveys.com/app#!/1119841/launch It has decent free options, but I think can only be used within 10 days. Labview embed 3D model on front screen. Works great with STL files. You can use this link to guide you on how to set the 3d display up so it looks nice. http://zone.ni.com/reference/en-XX/help/371361K-01/lvhowto/3d_configure_camera/
