TM4C129EKCPDT: Two CAN and USB can be used at the same time

Part Number: TM4C129EKCPDT

Hi

It only has one CAN can be used once USB has bee used. Is it a software problem or hardware issue? Thanks a lot. 

  • Hello Daniel,

    If you need to use PB0/PB1 for USB OTG then you cannot use two CAN bus as well. CAN1 pins are shared with USB0ID and USB0VBUS, so if the USB interface needs those signals then they cannot be used for CAN and you will only be able to use CAN0.
