#81917 - no need to use timer here Responding to: ???'s previous message |
Your program has a lot of logical mistakes. For instance,
1) label ERR is subroutine but you call it by JB time_out_flag,ERR instructions several times. 2) There is no JMP wiegand_rxstart to go to the beginning of the program. My advice is: put this program into a bin and start to write the new one. Just connect data0 and data1 lines to the external interrupt pins of MC and shift 0s and 1s into 12-bit SW register, that's all. And one more thing. If you want to get qualified help, comment the lines of your program. |
