Nothing, I just don't want to reconfigure my GPIOs and was wandering if it is possible to get the I2C peripheral to generate clocks - it looks like this is not possible like I suspected. Thanks
"Is there a way to get the F4 I2C peripheral to toggle the SCL line", and "SDA is externally held low by a slave device" - SCL is not held low obviously. I could try a different language?
