I2C Broadcom bug workaround. #254. Closed rewolff opened I've got a project I'm trying to control with I2C from a raspberry pi and I'm honestly close to just giving up and either switching to a beagleboard or having the Pi talk to an FPGA via SPI which then does the I2C stuff. The problem with that is that part of the I2C module would

Connecting an Arduino to a Raspberry PI using I2C – Peter

I2C defines several speed grades but the term baud rate is quite unusual in this context. The speed grades (standard mode: 100 kbit/s, full speed: 400 kbit/s, fast mode: 1 mbit/s, high speed : 3,2 Mbit/s) are maximum ratings.
