A USB pedal-based keypad with Raspberry Pi Pico and CircuitPython #RaspberryPiPico #CircuitPython #Keyboards @hackadayio
A lot of USB programmable pedals on the market need to install an application for configuration. Usually this app is only for Windows and came poorly translated (if translated at all). This is a pitfall for Linux or Mac users, who have only two options: To install a Windows virtual machine or ask a favor to a Windows user for pedal setup.
Here come to the rescue Raspberry Pi Pico, for two big reasons: USB native interface, so no programmer or additional hardware needed for firmware download and the most important: CircuitPython support. Programming could be “on the fly” without compiling-and-download during the debug phase. So Rpi Pico is the best candidate for a DIY pedal.
Developed using CircuitPython, friendly and easy to learn
Compatible with the most common operating systems
No need to install apps for initial firmware download
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
