How To Program a PIC Microcontroller on Linux using SDCC

Описание: In this video, I go over how to get started using a PIC microcontroller as well as programming and uploading your first program on GNU/Linux!

I go over what PIC microcontrollers are, how they work, and the advantages/disadvantages of PIC chips.

I explain the IC itself, how we can wire it to the programmer. I used a PicKit2 in this video (note that the PicKit3 drivers might not work on Linux).
The program is written in C, I used SDCC as the compiler, and PK2CMD to upload to the IC. I also have a demo of the blink circuit at the end.

Most tutorials I could find were for MPLab and other Windows only IDE's, so I wanted to showcase how it could be done on other OSes.

For this video, I used the PIC18F2550, you can follow along with many other PIC12, PIC14, PIC16 or PIC18 devices that are supported.

Production Remarks and Rants:
This video took quite a while to put together from the multiple cameras and audio tracks I was working with. I had to do some drastic color correction for many scenes in this, to get it looking better, brighter and at a proper white balance! As a result, there are a few glitches of transitions and short clips where the effects did not get applied.
This video originally had background music, I asked a couple of friends, and Bruce suggested removing any background music because "it was too distracting". If you don't agree with the change, please comment and tag him.
There is some distortion in the first camera clips from the mp3 compression the mic uses (it was an Olympus recorder), and I was probably too close to it. I applied more drastic noise suppression in the second half so there's less static. My XLR interface isn't working, so I couldn't use the mic I normally use for audio recording. Usually I put music to hide the noise, but removed it this time.
Everything except the Linux logo in the thumbnail is from this video, though I had to mess with the contrast a bit
