Another kind of switches could be used, so operation with different parts of the body is possible. So Rpi Pico is the best candidate for a DIY pedal.Īnother additional advantage over commercial USB pedals, the pedal itself can be replaced for a more robust one, without touching the circuit. Programming could be “on the fly” without compiling-and-download during the debug phase. 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. 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. Usually this app is only for Windows and came poorly translated (if translated at all). USB Pedal circuit installed in a robust enclosureĪ lot of USB programmable pedals on the market need to install an application for configuration. Works with almost any operating system, even with android devices using an OTG USB adapter. There’s no need for special application to download initial firmware nor for keys setup (only a simple text editor needed). Handy to use with video edition software to pause/play without moving the hands away from the keyboard or mouse, it can also be used by videoconferencing software to mute quickly.
