MSCAN on MC9S12C32 micro

[CANproject]

Hi

Does anybody have some knowledge  about the MSCAN module and the communication between two MC9S12C32 microcontrollers? I´m already using the AN3034SW example and is runnig good with some changes that I made to the code to fit on my micro, but I don´t know how to communicate two micros I just run the code in loop back mode, Please help me if you have some ideas for this. Thanks

I assume that you have the proper hardware between the two MCU:s? That is, CAN tranceivers and bus termination. Apart from that, it shouldn't be different from loopback mode.

HI

Thanks for the response. No I’m not using any transceiver & bus terminator, do you have some recommendations of any kind of transceiver & bus termination that I could use on my, project? Because with the loop back mode I just run the program and it seems to work great, but for my testing I need to build the bus between the two micros. Please let me know anything else that you could help me about this matter.

Thanks.

I'm using MCP2551 myself (assuming you are using high-speed CAN) which is good when it comes to transient voltages and EMC. Since the pinout is standard it doesn't really matter which one you pick.

Bus termination of 120 ohm is CAN standard.
