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.

Not really! At 126, the output is on all except the slightest little
sliver of off time. At 127, the output is on constantly.

Similarly at -127 there is the slightest sliver of off time and at
-128 the output is on constantly.

I do get steady ramping when using the sample program where the output
varies from -128 to 0 to +127 and back again.

I changed the sample code:

do A = -128 to 127
...
do A = 127 to -128 step -1

There is nothing different about 127 except that it doesn't have a
pulse at all. Just a constant DC level.

It's too bad RogueRobotics doesn't post their schematics. I would
like to see how the thing wires up to the OOPic.
