This Forum is Dedicated For all The Object Oriented PIC Lovers .......... The concept behind OOPic is straight forward. Use preprogrammed multitasking Objects from a library of highly optimized Objects to do all the work of interacting with the hardware. Then write small scripts in Basic, C, or Java syntax styles to control the Objects. During operation, the Objects run continuously and simultaneously in the background while the scripts run in the foreground telling the objects what to do.

So, why don't we start over with a link to the H-Bridge and motor that
you actually have?

Off hand, it seems close and you can't do anything about stall current,
that's what the motor will draw when it first starts rotating before
the motor starts generating back-emf.

Overheating from long term running at 1A is likely but can be solved
with a heatsink. Stall current and the 2A limit is not usually
negotiable.

Were it mine, I would opt for a much larger H-Bridge. Maybe the
Sabertooth 5A dual motor device.
