Tools:
Other versions may work, this is just what is currently tested
HW:
- KiCAD 5.0.1
SW:
- arm-none-eabi-gcc (GNU Tools for ARM Embedded Processors 7-2018-q2-update) 7.3.1 20180622 (release) [ARM/embedded-7-branch revision 261907]
- GNU gdb (GNU Tools for ARM Embedded Processors 7-2018-q2-update) 8.1.0.20180315-git
- ChibiOS-RT with community USB Host framework
- libopencm3 and DFU code from BlackMagicProbe
This repo uses several submodules, make sure they are up to date. After checking out the kicad-library repo, make sure to cd to it and run make to generate the actual KiCAD libraries.
SW Build Process:
- Make sure the arm-none-eabi toolchain is on your path:
which arm-none-eabi-gcc - Pre-build the libopencm3 library:
cd sw/ext/libopencm3 && make -j && cd ../../.. - Build the bootloader:
cd sw/bootloader && make -j && cd ../.. - Build the main application:
cd sw/scope-footswitch && make -j && cd ../..
SW Programming process:
- Connect SWD debugger (e.g. blackmagicprobe) to hardware
- Connect micro-usb from pc to hardware
cd sw/bootloader./flash.sh- Power cycle hardware, holding down the front panel button to force entry to the bootloader
cd ../scope-footswitch./dfu.sh

Questions
How big is the Scope footswitch PCB?
It measures 80 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Scope footswitch use?
98 parts. 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 Scope footswitch KiCad files?
From the MegabytePhreak/scope-footswitch repository on GitHub, at the commit this page was made from: the board is hw/scope-footswitch.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Scope footswitch design in my own project?
Its repository states no licence, so its author keeps all rights: ask MegabytePhreak before reusing the design.
