Variables |
| struct CANmsg | CanMsgR |
| | Structure to store CAN message just received.
|
| struct CANmsg | CanMsgT |
| | Structure to store CAN message to be transmitted.
|
| int8u | motor_id = 0xFF |
| | motor_id will be read from the EEPROM at boot time.
|
| int8u | position = 0x00 |
| | this is the position of the current FLASH_WRITTING operation ( 0 <= position <= 32)
|
This function writes to the EEPROM memory The only goal of this function is to write something different than 0xFF at the last memory location in EEPROM. This happens right after a flashing operation has been successfull, to make sure that at the following reboot of the PIC18F, it will boot directly to the user application and not stay in bootloader mode.
This function writes 0x42 to the last byte (address 0xFF).
