HammingDecode

[Olfox59]

Hi,

I'm working on 90641 sensors and always get -10 from HammingDecode().
I read properly the 832 eeprom dta, i compared it with my melexis dev kit board. The dump from Melexis PC Software and my uC reading are exactly the same (tried several reading, each time the same).

I comapred datasheet and API files and i see differences in parity computation:

`from datahseet: /P0 = D0 + D1 + D3 + D4 + D6 + D8 + D10/
in original API files from git //parity[0] = D[0]^D[1]^D[3]^D[4]^D[6]^D[8]^D[10]^D[11];
what i tried without succes : parity[0] = D[0]^D[1]^D[3]^D[4]^D[6]^D[8]^D[10];

    /*P1 = D0 + D2 + D3 + D5 + D6 + D9 + D10*/
    //parity[1] = D[0]^D[2]^D[3]^D[5]^D[6]^D[9]^D[10]^D[12];

parity[1] = D[0]^D[2]^D[3]^D[5]^D[6]^D[9]^D[10];

   /* P2 = D1 + D2 + D3 + D7 + D8 + D9 + D10*/
    //parity[2] = D[1]^D[2]^D[3]^D[7]^D[8]^D[9]^D[10]^D[13];

parity[2] = D[1]^D[2]^D[3]^D[7]^D[8]^D[9]^D[10];

    /*P3 = D4 + D5 + D6 + D7 + D8 + D9 + D10*/
    //parity[3] = D[4]^D[5]^D[6]^D[7]^D[8]^D[9]^D[10]^D[14];

parity[3] = D[4]^D[5]^D[6]^D[7]^D[8]^D[9]^D[10];

    /*P4 = D0 + D1 + D2 + D3 + D4 + D5 + D6 + D7 + D8 + D9 + D10 + P0 + P1 + P2 + P3*/
    //parity[4] = D[0]^D[1]^D[2]^D[3]^D[4]^D[5]^D[6]^D[7]^D[8]^D[9]^D[10]^D[11]^D[12]^D[13]^D[14]^D[15];

parity[4] = D[0]^D[1]^D[2]^D[3]^D[4]^D[5]^D[6]^D[7]^D[8]^D[9]^D[10]^D[11]^D[12]^D[13]^D[14]^D[15];

If my eeprom dump is correct, and there is a mismatch with the datasheet, i wonder if this Hamming Decode function is implemented in the same way in PC software. It seems to be a mandatorry step to demodulate original eeprom content and to be able to use it for the next function so i really need to understand why there is this transmit error detected whereas the pc software doesn't complain with the same dump content.

But why my changes is not efficient enough to solve the issue? I join you my eeprom dump content read by melexis pc and mine uC in case you would like to try it:

Thank you !
