EK-TM4C1294XL: I2C issue with TM4C1294NCPDT

Alberto Soattin
Genius 16905 points
Part Number: EK-TM4C1294XL

Hi Support,

my customer is facing issues with the I2C communication between the EK-TM4C1294XL and some I/O expanders.

Following the datasheet indications, the communication did not work properly and a delay had to be added. However this feels like a hack and is not described in the datasheet. I have a word document better describing the issue and customer code, if needed.

Can you kindly help me solving the issue?

Thanks and regards,

Alberto
