Buildbotics Controller Schematics & PCB Layout
The top-level schematic is in the file
buildbotics_controller.sch. To view
and edit the schematics run:
You must have
make and the GEDA tools install. Other make commands are:
pcb- Open the PCB editor.
bom- Create Bill of Materials as
net- Generate the netlist as
drc- Run the Design Rule Checker.
layout- Initialize the PCB layout.
attrib- Edit schematic part attributes.
zip- Create a zip file from the Gerber and drill files.
tidy- Remove all backup files.
clean- Remove all autogenerated files.
Copy the system gnetlistrc file:
mkdir -p ~/.gEDA
cp /etc/gEDA/system-gnetlistrc ~/.gEDA/gnetlistrc
~/.gEDA/gnetlistrc and comment out (insert semicolon) the line that
and uncomment the line that reads:
The resulting lines should look like this:
This allows power and ground rails to be routed between schematics without
mangling the names. Note, that as a consequence of this setting you cannot
net attributes in any schematic modules that are used more than once
with out having them all connected together.
Set the library path in PCB to point to the local footprints folder. Use
File->Preferences->Library in PCB to do this.
