| Hello once again. I wonder, am I able to use different timers for different tasks in a project or am I restricted to one? If yes, do I declare the other timer(s) at start of code or within the concern ... | |

| My apologies for the late response when I need help. The output pins are RB5 and RB6 of PIC16F690. If I disable PWM, they work ok. I thought maybe the PWM is using up power. I also read somewhere of ... | |

| Can someone please tell me if I should expect full bridge operation just by running this code. Or am I supposed to add more code like forward and reverse?
