FlexCAN0 sample project for MK22FX512AVLH12

[srikanth_vemula]

Hi,

We're using FlexCAN0 module of MK22FX512AVLH12 Micro-Controller. As it is first time for me to work on CAN, to get familiarized, I've been searching for a sample project, specific to this MCU. But I could not find anything. Please share sample code for FlexCAN0 module, which can transmit & receive 8 Bytes of data in external loop-back mode.

And Please let me know that Is it mandatory to have atleast 2 nodes on the CAN network for transmission?

Quick response is appreciated.

Regards,

Srikanth.

P.S. You need either an active receiver or a loop-back to be able to transmit CAN frames.

Hi,

First I would like to attach a useful training material for Kinetis FlexCAN moduble for your reference.

As for the sample driver, please use the attached sample code, you can find the can_loopback sample from:
