Ok thanks
I'm trying to read, but the main issue is, that there are very FEW code examples on forums focused exactly on topic being asked.
Say someone asks "how to debounce ADC input" and someone posts a huge code for completed device, where that code is present, but it is hidden somewhere and you have to guess where is it, which other variables and changes it uses, from that code and so on.

Contrary to them, the code examples supplied by melabs are short and spot on - they do what they have to do, only few extra lines are present.

By the way, I got big module running with parallel interface with PBP. The issue was that it needs about 330mA to operate, and PicKit 3 was not able to provide enough juice. With the help of external 5V supply, issues solved
