Page 10: Appendix 1: Crc Calculation Algorithm
Projector Control APPENDIX 1: CRC CALCULATION ALGORITHM The following ‘C’ code can be used to calculate the 16-bit CRC required for all packets. The CRC is contained in the packet header and is calculated for the entire packet (header plus body). The CRC calculation is performed with the CRC bytes of the packet header initialized to zero. - Page 11 Projector Control static const BYTE cCRCLoArray[] = { 0x00, 0xC0, 0xC1, 0x01, 0xC3, 0x03, 0x02, 0xC2, 0xC6,0x06, 0x07, 0xC7, 0x05, 0xC5, 0xC4, 0x04, 0xCC, 0x0C, 0x0D,0xCD, 0x0F, 0xCF, 0xCE, 0x0E, 0x0A, 0xCA, 0xCB, 0x0B, 0xC9,0x09, 0x08, 0xC8, 0xD8, 0x18, 0x19, 0xD9, 0x1B, 0xDB, 0xDA,0x1A, 0x1E, 0xDE, 0xDF, 0x1F, 0xDD, 0x1D, 0x1C, 0xDC, 0x14,0xD4, 0xD5, 0x15, 0xD7, 0x17, 0x16, 0xD6, 0xD2, 0x12, 0x13,0xD3, 0x11, 0xD1, 0xD0, 0x10, 0xF0, 0x30, 0x31, 0xF1, 0x33,0xF3,...
