Pic16 Timer0 puzzle
INTRO
The whole point of a timer with overflow interrupt is that the interrupt will trigger on a precisely timed interval - so long as the code executed in the interrupt doesn't take longer than the timer interval.
THE PROBLEM
On a PIC16LF1823, I…

How to configure RC3 pin as output in PIC16F886?
I already used it with a PIC18 and the RC3 pin is working for me, but for the PIC16F886 the 14th pin is described as "RC3/SCK/SCL", however, in picture 18 it is described as only "RC3".
Any head start / help that someone can provide?

How would I connect to these ICSP pins and what is the purpose of the transistor?
I have an old tire pressure monitoring system and was hoping the PIC16F886 in it doesn't have the code protect bit set so that I can modify the behavior of it (namely turn off the beeping from it in certain scenarios but not others.) It has one set…

PWM-modules operating simultaneously on different frequencies
I am using a PIC16F15345 which has 4 10-bit PWM modules.
In order to minimize electromagnetic interference I tried to use the PWM-modules on different frequencies working simultaneously, but it did not work.
According to the data sheet (page 328)…
