Hello!
I need a variable timer using a PIC but I didn´t have success. When I say variable I mean that I have to change the range of counting, for example, sometimes I need to count from 1 second to 1 minute but sometimes I have to count from 1 second to 3 minutes. Sometimes I have to have a port ON for 1 minute and sometimes for 3 minutes. I´ve tried to change the clock, instead using a cristal based I used a RC clock, changing the resistor and capacitor, but it didn´t work. Does anyone have a sugestion on how to do it?
Thanks.
