Now I am using FRDM-K22, the Mico chip is MK22F51212. Now I need CAN bus function? I want to know if MK22F51212 have CAN bus contrroller? So I just add CAN tranceiver, and then can simulate CAN bus communication.
I think I get the Pin28 and Pin 29 of MK22Fx512 64pins are for CANTX and CANRX. And which is FlexCAN bus demo SW example?
Update the above information, seems that FRDM-K22F use MK22FN512LVH12, MK22FN512LVH12 doesn't have CANbus pins, but MK22FX512LVH12 have CAN bus pins. My question is that:
#1, Which difference between 2 chipsets? Just CAN bus pins different?
#2, In the P220 of "K22P64M120SF5V2RM" and P61 of "K22P121M120SF7-Datasheet, there are different pinout defintion. which one I should refer if use MK22FX512LVH12?
#3, If I want to use FlexCAN bus , there are CAN example demo SW with MK22FX512LVH12? Is there CAN library for MK22FX512LVH12?
First of all, sorry for the so later reply.
For the K22_120MHz product has different device version, which original from different Kinetis product family.
That's why some K22_120MHz product has FlexCAN module, while another without.
Please check here for the detailed info.
About FlexCAN example code, please refer attached FlexCAN module validation code.
Wish it helps.
BTW: Merry Christmas and Happy New Year!
