C# Wireless Dashboard
This is a C#/.NET application I made for real-time wireless plotting and PID tuning for one of my Ganzbot robots.
Features
- wireless link via low-cost HC-05 Bluetooth modules ($8 US)
- HC-05’s reconfigured for 57.6 Kbps and to only pair with each other.
- increases the speed from the default 9600
- pairs at power-up every time – avoids incessant blinking light “searching for pairing” headaches
- real-time scrolling plot of 6 signals @ 20 Hz
- signal list can be reconfigured wirelessly while plotting
- “macro” buttons to batch reconfigure all 6 signals simultaneously. Groups include – raw sensors, state estimator, pitch PID, speed PID, etc.
- real-time wireless modification of PID gains
- fields for direct user access to command interpreter
- play, pause, save features
Notes
On my robot I’m using a Teensy 3.2 and a 2nd HC-05 module. No need for a Pi, or a board with Wi-Fi or anything complicated. Any MCU with a UART is fine.
Viewing plots and tuning gains/thresholds real-time with no tethers – even 6 signals at 20 Hz – is really nice to have for balancing robots and this project is a very low impact way to get there.
Written in C# using Visual Studio. Code needs some cleanup before posting to my GitHub. Stay tuned.
