Pyramid card is Wiegand communication protocol and it is already realized in Proxmark3 repo, so idea is add this code to Chameleon Ultra. Here is file in proxmark repo - "wiegand.c" (full link is https://github.com/RfidResearchGroup/proxmark3/blob/master/armsrc/wiegand.c)
And there is code for pyramid cards support:
case 39 : // 39bit KERI System Pyramid fc &= 0x1FFFF; // 17bits cn &= 0xFFFFFFFF; // 20bits value = fc << 20 | cn; num_to_bytebits(value, 37, temp); wiegand_add_parity(temp, dest, 37); break; case 44 : // 44bit KERI system Pyramid oem &= 0xFF; // 8bits fc &= 0xFFF; // 12bits cn &= 0xFFFFFFFF; // 21bits value = oem << 20 | fc << 12 | cn; num_to_bytebits(value, 42, temp); wiegand_add_parity(temp, dest, 42); break;
if it only was that easy lol
also #185
so sad. Hope, that it will be added one day
