Hello List,

I have a design using an 16F877, with the port C driving a 7 segment =
display. The 4 digits are driven by port B. All was well till I decided =
to add a certain feature that required the hardware PWM. Since I had an =
extra pin on port C, I re-wrote the display driver such that all the =
other 7 pins besides port C.1 are used by the display, leaving C.1 for =
the HPWM out.

Now, I find that the display is beving in a very unexpected manner.=20

Was it a bad idea to share the display and the HPWM on the same port? Or =
can I mask the display output on port C to ignore the PWM output =
(although the display itself does not use it)?

Or is the only soution to relocate the display to another port?

Thanks in advice for any suggestions.
