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)
