Discussion - Software / Re: A linux, a UM232H and a I2C device - now what do i do with it?
« on: May 26, 2020, 08:26:08 AM »
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
