Firmware:

The firmware running your bike's motor, consists of three parts:

• A bootloader, started on powerup.
• The actual firmware, called application executed by the bootloader.
• Configuration memory, stored in ROM.

The bootloader uses two blocks to identify the harware it's running on, and what firmware should be loaded. The firware uses one block to read/write settings, which are currently the strain gauge calibration.

If you wan't to build a control PCB, use the latest revision of 3phasecntrl.

New Hardare Revision Wishlist:

• Crystal
• ESD protection on HALL input. (REV2)
