For the SPI connector see: SPI_connector_pinout.

The output connector is connected as follows:
(Looking at the business end of the connector, counting from left to right)

pin function
1 Output A1
2 Output A2
3 Output B1
4 Output B2
6 Vin



jumper settings

See solder jumpers on how to change the solder jumper.

By changing the solder jumper SJ1, you can make connector SPI1 (nearest to the board edge) into the ICSP programming connector for the ATmegaxx8 on the board.


To make the motor PCB do things, you need to send things over the SPI bus to the PCB.

The general overview of the protocol is here.

The specific commands for the motor PCB are explained in Spi_motor_protocol.

For arduino, a sample PDE is available, called ardemo_lcd.pde, also at BitWizard software download directory .

This is a demo to send things using SPI to the lcd board. The SPI routines there are applicable for the motor board as well.
