PIC firmware build
Building the PIC firmware on a Linux system
You will need to have a few packages installed:
$ sudo apt-get install build-essential cvs subversion bison flex
You also need to have gputils and SDCC installed. The standard version of gputils contains a bug, so you need to download a later one. Uninstall gputils and/or sdcc if the standard versions are already installed on your machine. Then...
Create a directory for tools needed for RepRap firmware build and put gputils in it:
$ mkdir $HOME/reprap-tools $ cd $HOME/reprap-tools $ cvs \ -d:pserver:[email protected]:/cvsroot/gputils \ login $ cvs -z3 \ -d:pserver:[email protected]:/cvsroot/gputils \ co -P gputils $ cd gputils $ ./configure --prefix=$HOME/reprap-tools $ make $ make install
Not all versions of SDCC work. In particular some later revisions have bugs that are not present in earlier versions. Revision 4943 is known to work with RepRap. Once again, put this in the directory you created:
$ cd $HOME/reprap-tools $ svn co -r 4943 https://sdcc.svn.sourceforge.net/svnroot/sdcc/trunk/sdcc $ cd sdcc $ ./configure --prefix=$HOME/reprap-tools --disable-mcs51-port \ --disable-gbz80-port --disable-z80-port --disable-avr-port \ --disable-ds390-port --disable-ds400-port --disable-xa51-port \ --disable-hc08-port --disable-ucsim $ make $ make install
RepRap PIC Firmware
If you are doing RepRap development you will almost certainly be using Eclipse for the Java host code anyway. Use subversion in Eclipse to check out
and move to the directory where Eclipse put that:
$ cd ~/workspace/firmware
Add the directory you created previously to your path:
$ PATH=$HOME/reprap-tools/bin:$PATH $ export PATH
Now make the RepRap PIC firmware:
$ ./configure $ make
That should create five .hex files for the PIC16F648 (or PIC16F648A - either will work):
The first three are for the axis stepper controllers.
The file extruder0.hex is for the standard thermoplast extruder.
The file extruder1.hex is for the experimental paste extruder.
Rebuilds and options
To do a rebuild, in the ~/workspace/firmware directory type
$ make clean $ make
The standard distribution has the X, Y, and Z axis code set to do half-stepping on the stepper motors. To change this to full stepping edit the file:
comment out the line that says:
and do a rebuild.
