Introduction
This code describes my firmware. My intention is simply to document (with working code) the various tricks that I think I've done first (or best).
Download
The license for the firmware is CC-by-3.0. And it can be downloaded from this link...
In order to compile it, you'll also need to install two supporting libraries (MIT licenced)...
What File Does What?
- config.h contains the description of the printer (in terms of steps/mm, maximum feedrate, baud rate to use, etc.)
- parse.c contains the gcode parser
- cmd.c contains the command interpretor
- dda.c contains the line drawing algorithm
- divide.c, log.c, dist.c contain supporting functions for dda.c
- hw/ contains the real implementation of all the various things that the hardware does. All the AVR specific code is here.
- hw/pins.h contains a description of the motherboard (which pin drives what thing)
- sim.c contains a simple implementation of all the hardware functions. This allows one to test a firmware before uploading to a printer.
- host.c contains a simple terminal program that can send gcode files to the printer.
Pressure Management
The unique feature of this firmware is the pressure management code. This code is contained in dda.c.
