Hello
I have an application on a F2802 with CAN, I2C (EEPROM) and some GPIOs.
After the initialisation i read data from the EEPROM and transmit a CAN message.
If i read the data from the EEPROM and GPIO22 (configured as input) is high,
then the CAN message can not be sent.
When the input is low or i dont read the data before sending a CAN message
it works.
Can someone explain me that strange phenomenon?

Philipp,
This is very strange occurrence as GPIO22 has no I2C or eCAN multiplexed on this pin. Have you tried modifying the example projects from the C280x, C2801x C/C++ Header Files and Peripheral Examples (SPRC191) to see if you receive the same results? You can download this software from the following link:
