Errata

Please note the following problems with the current badge as well as workarounds.

In both badge versions: Reverse the polarity of D3 from what is indicated on the board

Novice version: Pins 1 and 2 on the voltage regulator are swapped.  Using wire, jump each pin to where the other is supposed to be.

Finally, the initial code flashed includes buggy LED flashy code.  However, it should include a working USB bootloader.

Steps required to program new stuff for your badge:
  1. Install MPLAB IDE  Download here
  2. Install C for PIC8 compiler Download here
  3. See the “Application libraries” link below for access to all of the sources for drivers, demo projects and bootloader binaries.
