Discussion - Software / A linux, a UM232H and a I2C device - now what do i do with it?
« on: May 18, 2020, 06:02:35 PM »
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
