Serial Checksum calculation

[accr]

Hi to all,

maybe this is a dumb question…
I would like to know how the checksum is calculated in RS232 serial connection used by Race Technology.

The serial stream is composed of the following bytes stream:

[header][data1] [data2] [checksum]
[0x14][0x10][0x10][????]

Thanks!

Hello,

It is the LSB of the sum of the messages including the header. So in this case 0x34

Thanks, but what is LSB? Least Significant Bit?

[Support]

Least significant byte. If you had a message

0xAA 0xBB 0XCC 0xDD

3OE is the sum of the messages, making the the checksum 0x0E.
