Compiling
Coprocessor
$ mkdir -p build/glyco
$ cd build/glyco
$ meson ../.. --cross-file ../../cross/avr-atmega2560-cross.ini
$ ninjaTo use the provided flash target to flash the coprocessor, set the coprocessor port the arduino is connected with by passing -Dport=/dev/<port> to meson (usually /dev/ttyUSB0) and add yourself to to appropriate groups (typically dialout or uucp).
Debugger

Questions
How big is the Glycon PCB?
It measures 120 × 120 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Glycon use?
61 parts, built around the 74HC244D, 74HC32D, 74LS139PC and IRF9540NS. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Glycon KiCad files?
From the Snektron/glycon repository on GitHub, at the commit this page was made from: the board is hardware/kicad/glycon.kicad_pcb and its schematic doc/ledmatrix/ledmatrix.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Glycon design in my own project?
Its repository states no licence, so its author keeps all rights: ask Snektron before reusing the design.
