Debugging sensors on a microprocessor can be a hassle and the most used approach is to output the sensor values to a serial monitor. I made a realtime plotting tool which is a better and more visual way of doing the same thing.
I created this software to debug an Arduino Due on my self-balancing robot. To tune the controls of the robot I needed fast feedback to know if I was making progress or not. The video below demonstrates typical use of the realtime plotter:
- Real-time plotter of your data while it is still being processed by your application
- Plots live data from serial port. Microprocessor choice does not matter as long as it can send serial data to your computer.
- 6 channels of data (and this can be increased if necessary)
- Live bar charts
- Live line graphs
- You just send the data you want to debug with a space as delimiter like this "value1 value2 value3 value4 value5 value6". Floats or integers does not matter.
- Open source
- Robust. It will not crash because of corrupt data stream or similar.
- Multi platform Java. Tested on OSX and Windows 8 (and should work on Linux as well).

Just wanted to share it if someone else will find it useful.
