Hello,

i use the TI F28335 with Code Composer Studio v3.3 and the Target Support Package for C2000. I have a problem with receiving data via eCan. The data i want to receive is an uInt32. I get a Can data Massage and try to unpack it in the "eCan Unpack" block. Everything works pretty good but the value i get out of my eCan Unpack Block is not right.

For example: When i try to receive a value greater than 65535 the value i get out of the "eCan Unpack" block is wrong. The bits from 2^0 up to 2^15 were correct and the bits 2^16 up to 2^31 were always 0.

In the "eCan Unpack" block i use the option "manually specified signals" and i have set the signal parameters as they are set in the other Can devices.

I hope someone knows what i do wrong.

Thanks for any answer

Hello, i suppose that the "eCan Unpack" Block isn´t able to handle 32-bit values.

Do you get any warnings in the command line while generating code? If so, can you post the build output here. I assume you are using the eCAN Receive block with the CAN Unpack block?

Thanks
