Last year I built a few Build Buttons for my firmware team. If you are going to build/debug all week you might as well have fun doing it.

 

I used a Teensy as USB HID to send F7 when the B0 signal was shorted. I then configured Eclipse to Build All & Run Debug on a F7 key entry.

 

This is a simple fun project & I'm getting used to slamming the Build Button while I'm hacking up some FW.

 

If you want to take this project to the next level... consider adding a battery & Bluetooth module to cut the cord!
