But so far is there any problem in the code? It won't compile though, keeping saying there is syntax error, for example in line 1 symbol....
Also, PIC16F84 just detect whether the input BCD signal from Hm2007 is 55,66,77 error code, if not, it will pass the input to output unchanged and let the 74HC154 to do the decoding. This is what the book says. Please help, I am so lost now.
