Hello all, In MpLab with XC8 the timer on and off control is called TMRxON,=20 where x is the timer number. So for my program to turn timer1 on or off=20 the instruction is: TMR1ON =3D 0; //The timer is off TMR1OFF =3D 1; //The timer is on. This is in the 16f684 datasheet. I thought I would let everyone know. Thanks, rich!
