Original question:
Tool/software:
How can I check is a MCAN TX FIFO has free space to write next message?
Hi,
You can refer to the following steps for quick find.
1. Import MSPM0G3507 CAN transmission related project in SDK into CCS. Here I choose the "mcan_multi_message_tx" project as an example.
2. Compile the project.
3. In the main function, press down ctrl and click on any function starting with "DL_MACN_", here I choose "DL_MCAN_writeMsgRam", and then enter the "dl_mcan.h" file.
4. Search "DL_MCAN_TxFIFOStatus" in "dl_mcan.h", you can find the following function and the definition of TX FIFO related status. Also you can get more information in MSPM0G3507_TRM 21.4.15.
