LP-MSPM0G3507: CAN Communication

Hi Siddharth,

Do you connect the can transceiver to the LP-MSPM0G3507? And if the can transfer example of SDK is used, the receiving end parameters has to be configured match to the example.

There is a guide about MSPM0 CAN usage: CAN Introduction Lab , hop it will be helpful to you.

I dont have CAN transceiver right now . are there any other possible ways i have CAN analyzer and i can share the ss 

This picture is of when i dumped the mcan multi message Tx and wanted to check the output

Hi Siddharth,

The CAN transceiver is necessary to evaluate MCU CAN example.

Actually there are usually internal CAN transceiver in CAN analyzer, but another CAN transceiver is needed for MSPM0 if it is used as a CAN point.

What is CAN point ?

Sorry, maybe CAN node is more accurate. It means the end equipment that could transfer or receive message from CAN bus. 

Please refer to CAN Node - CAN bus - Wikipedia for more CAN protocol information.

OK so WE need a one CAN transceiver right . I have one CAN transceiver But i dont think so it is Compatible that is MCP 2515 Am i right 

Hi Siddharth,

Yes, for a CAN communication, there need to be at least two CAN transceiver. As you use CAN analyzer and there is internal CAN transceiver, so you need another CAN transceiver for MSPM0.

It seems MCP2515 is a SPI interface CAN controller, I'm not sure what do you use this for, as there is already CAN controller in MSPM0G3507.
