Main components
1README
README.mdPico Coffee Roaster
Mini torrador de café baseado no Raspberry Pi Pico.
Este firmware é capaz de realizar o controle de uma resistência utilizando um triac, além do controle de um motor e de um fan via PWM. Também estão disponíveis periféricos como displays, termistores NTC, termopares PT0, controle PID, entre outros.
O projeto utiliza o pico-sdk como base. Além do pico-sdk instalado e configurado no PATH do ambiente, também é necessário instalar o pico-extras.
Build e load
Para compilar o projeto utilize:
mkdir -p build
cd build
cmake ..
make -j$(nproc)Para enviar o firmware para o Pico utilize:
cd build
picotool load pico_roster.uf2 -fCertifique-se de que o picotool esteja instalado e disponível no PATH do sistema.

Questions
How big is the Motors PCB?
It measures 63 × 60.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Motors use?
29 parts, built around the IRF540N. 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 Motors KiCad files?
From the CH-Microsystems/pico_coffee_roaster repository on GitHub, at the commit this page was made from: the board is hardware/motors/motors.kicad_pcb and its schematic hardware/control/control.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Motors design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
