I'm still struggling with the serial download for the ADuCM350.
I have now revision 0 of AN-1262. On page 3, CS is defined as
0x00 - NumberOfBytes - SumOfDataBytes
According to what I sniffed from the CM3WSD, CS should rather be defined as
0x00 - NumberOfBytes - CommandByte - SumOfAddressBytes - SumOfDataBytes
This is also what the sentence "Expressed differently, the 8-bit sum of all bytes excluding the
start ID must be 0x00." implies. It looks like there are two different definitions in the same paragraph.
Best regards, Enpa
