This is my first project, I am new on picaxes, trying to add code to tun on pin 5 as the first time is meet, as soon as the second time time is meet pin 5 needs to go off. I did some modifications to a program i found in the internet, using picaxe 08m adapting to meet requirements on 08m2+ is running good. code is as follows.
What I need is the code to turn on C.0 at first programmed or checked against ds1302 RTC and another time turn C.0 off how can I compare the times to turn on and then turn off any help on how to write the code is more than well come.
Thanks in advance to every one.
Code:
; picaxe 08M2+ and
; DS1302 Opcodes
symbol WriteCtrl = %10001110
symbol ReadSecs = %10000001
symbol WriteSecs = %10000000
symbol ReadMins = %10000011
symbol WriteMins = %10000010
symbol ReadHrs = %10000101
symbol WriteHrs = %10000100
symbol WriteTrickle = %10010000
symbol TrickleSet = %10100101
; DS1302 Connections
