bwboards

Private Zephyr board definitions for Blumenwagen hardware.

can_dimmer_c3

The board is based on the ESP32-C3 Super Mini reference board.

Function GPIO
CAN TX / CAN-D 0
CAN RX / CAN-R 21
Dimmer PWM output 3

The UART console uses the ESP32-C3 USB serial device. CAN is configured for 500 kbit/s.

The CAN transceiver and PWM pin assignments are defined in boards/can_dimmer_c3/can_dimmer_c3-pinctrl.dtsi and boards/can_dimmer_c3/can_dimmer_c3.dts.

Build an application with the board before adding the module to the west manifest:

west build -b can_dimmer_c3 \
  -d build/can_dimmer_c3 \
  -- -DBOARD_ROOT=/path/to/bwboards
