#143330 - a checksum out of 2 bytes? Responding to: ???'s previous message |
Christoph Franck said:
To avoid the all-zeros scenario, define the checksum as - (lsb of sum of data bytes), NOT (lsb of sum of data bytes) or something similar. You mean a checksum byte with the 2s complement of the sums lsb and one checksum byte with the 1s complement of the lsb of the sum? Matthias |
