LEDs

The only LED is a power indicator.

jumper settings

See solder jumpers on how to change the solder jumper.

By changing the solder jumper SJ1, you can make the connector SPI1 (nearest the board edge) into an ICSP programming connector for the attiny44 on the board.

Protocol

The general overview of the SPI protocol is here.
The board specific protocol can be found here: DIO_protocol
You should also read the General_SPI_protocol notes.
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 3fets and 7fets boards as well.
