Graphing Data From Brain

[ryan_mc]

Hello All,
A teammate and myself are doing a project regarding the feedback from the V5 Smart Motors. We have figured out how to get this feedback to print to the brain, but we would like to graph it; especially the efficiency feedback. If anyone knows how to graph feedback directly from the V5 Brain to a spreadsheet or computer-based graph, it would be a great help.
Thanks, Ryan McLoughlin

You could save whatever data you want to an SD card on the brain in CSV format, then import that into e.g. Excel and graph it there.

You could find examples of saving data to files on SD card in this topic:

SD Card Help

Here’s a simple example showing how to use the VCS SD card save and load file API. This saves some information into a file called “test.h” on the SD card and then reads it back again. #include "robot-config.h" // storage for some information to save uint8_t myTestData[ 100 ]; uint8_t myReadBuffer[ 1000 ]; int main() { // set the test data to something detectable for(int i=0;i<100;i++) { myTestData* = i * 2; } // write test data to SD Card int nWritten…

You can save anything you want to files on the SD Card including text files. You can also stream text to the terminal window real time (within the limits of the connection you are using) that you can then cut and paste into a text document.

We graphed some random robot exported data for fun. We used Logger Pro for our graph. This is what our graphs ended up looking like:
