Hii am trying to write a pic basic prg to make a 2 digit 7 segment led display count down timer that starts at 10 stays at 10 for 3 sec then continues to count down in one minute intervals to 09 08 etc to 00 then goes back to 10 again and keep repeating until unit is powered off. I don't know how to start programing the leds . I have downloaded some 2 digit countdown timers but they are all either in C or asm or hex can anyone give me a few pointers of where to start I would like to use the pic 16f683 and common cathode seven displays , are there routines for 7 seg. led displays ??? I am very new at this. thanks Ray
