[quote] So you mean to say that 2803x and 28379D have a different approach for the Can peripheral. [/quote] Yes, the modules do conform to the CAN protocol, but the implementation is completely different between the devices. [quote] I was able to communicate between two launchpads but I am wondering if I can do without the driver. [/quote] Whether or not to use a driver like the C2000ware API is completely up to you. If you decide not to use it, you need to come up with your own way of writing to the registers/bits. [quote] The document you have shared TMS320x28xx eCAN applies to 280379 as well right? [/quote] No, it is applicable only for the 28xx devices with eCAN. [quote] Like the code snippet as below for 2803x is there a way for 28379D[/quote] You *can* do 32-bit R/W with HWREG()
