The write-test-debug loop for the KiT has been massively improved by having an emulator–and now I can run KiT code away from home!
After much design, soldering, and debugging, the breadboard KiT 1 has been succeeded by an improved KiT 2 on PCB!
I wrote a simple monitor program using the LCD and keyboard input that allows you to program the KiT–from the KiT itself!
