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


The general overview of the SPI protocol is here.
The board specific protocol can be found here: spi_dio_protocol

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