How to do an IIC bus communication with a PCI-6025E board.

With at least 50 Khz clock signal.

Hi Bierzo,

I do not believe that IIC comunications can be implemented using a PCI-6025E without extensive external hardware.

Durring data transfers, the clocking signal is provide by the slave.

I have written LV interfaces to allow IIC communications via a third party board using their .dll's. This was quit involved because the multiple bus mastering scheme dictates that the bus transaction can be interupted at any time by another device.

Since then, I have heard that other IIC interfaces are now available with LV drivers.

This is as much as I can say without "giving away the store".

I hope this helps,

Ben
