Post by thread:[PIC]: i2c Error Checking Considerations

Hi, all. I am about to implement error checking on top of the PIC's i2c MSSP subsystem. I have a C language snippet of CRC-16 (divisor polynomial x^16 + x^5 + x^2 + 1), and am wondering if anybody is using this. If so, is there assembly source available on the web? If not, what is commonly used in the i2c world for handling bit flips between master and slave? Thanks!

Here is a few asm CRC routines: http://www.piclist.com/techref/microchip/crcs.htm ---- Original Message ---- From: rostaman <spam_OUTrostamanTakeThisOuTONEBOX.COM> Sent: Monday, February 19, 2001 23:13:10 To: .....PICLISTKILLspam@spam@MITVMA.MIT.EDU Subj: [PIC]: i2c Error Checking Considerations {Quote hidden}> Hi, all. > I am about to implement error checking on top > of the PIC's i2c MSSP subsystem.
