Dear fellows,

I've been looking around the datasheets for the STPC Elite for details on the I2C port. In the Datasheet for the Elite it references port 22h/23h index 97h, although it says nothing about which bits do what. Had a quick look at the other datasheets including the programming datasheet but to no joy! Anyone know how to program the i2c interface?

The i2c port of the STPC Elite is a rest of the DDC lines from graphics part of the other STPCs. This DDC lines are part of the VESA standard to communicate with the screen but you can re-use it for your own purpose.

It is a software based i2c and you can find source code to drive this 2 lines in the STPC kit.
