This is the first version of the wi-fi printer, and my comments probably aren't great at points. Some of the coding was done in a half-assed way that "worked". In future revisions I will clean up the code, make it more efficient and portable. The micro I used was the PIC18LF25K22, and I used the MPLABX ide.
If you have any questions, don't hesitate to ask, it isn't always clear why I did what I did.
