Built-in LED status indicator
The AM controller has a built-in LED which indicates the state of the control program:
- Bootloader -- LED lights very briefly while firmware version and checksums are checked. If the controller remains in this state for more than a few seconds, there is a firmware problem. Try updating the firmware.
- Main program -- LED is lit while the Driver initializes.
- Driver -- the motor control part of the firmware:
- LED off -- Driver successfully initialized, motor can be driven
- LED on solid -- Driver status word is non-zero, a high priority limiter may be active. LED turns off after 2 second timeout when condition passes.
- LED blinking -- an error occurred. LED blinks 16 times, pauses, then repeats. Each blink represents one bit of the error word (long blink = 1, short blink = 0, LSB first).
