#142769 - RE: simple
Responding to: Jan Waclawek's previous message
I thing I'm missing something fundimental here.

Can I get an example of the calculations for the first few bytes of a table?

Here is a snippet of a table I found online (somewhere?) for a CRC8 with a POLY of 0x0107. I want to be able to conform this table is correct.
const char code crc8table[256] = {
	0x00, 0x07, 0x0e, 0x09, 0x1c, 0x1b, 0x12, 0x15, 
	0x38, 0x3f, 0x36, 0x31, 0x24, 0x23, 0x2a, 0x2d,
	0x70, 0x77, 0x7E, 0x79, 0x6C, 0x6B, 0x62, 0x65,


I tried using the crc calculator at
http://www.zorc.breitbandkatze.de/crc.html but my results don't seem to make sense.

Thanks,
John
