Hello and thanks for the reply,

I have done already what you describe. And what do i have to do next to communicate with a I2C device? Do i have to put the UM232H into I2C mode, or ist the software doing this? Which pins are the I2C pins? Do the pins need external pullups or are they chip-internal and can be controlled by software?

As described, i don't see the complete I2C signals on the pins. I have seen one pin which had some kind of data on it, but there was no I2C clock on any pin, so the data i have seen could just be a RS232 signal or something like that...

Kind regards

Hello,

Is there maybe a guide what i actually have to do to connect a I2C slave device to a PC and communicate with the device in Linux? For the conversion i would use a UM232H module.

The application notes i found so far explained always just a part, not the big picture. With the research i have done so far i found out that using D2xx and libMPSSE should do it on the software side. Compiling was successful, running the static example (static_link) also until it waited for incoming data.

But now what do i do with the UM232H? Do i have to configure it somehow? To which of the 16 connections do i attach my I2C device? I looked at the wires with a scope; one wire obviously had a data transfer on it. But there was no wire with the clock...

It would be really helpful if there was a document which just says: Do this, do that and so on, to avoid all this time consuming research.

Kind regards
