After a little research with ChatGPT I found out that I can use a Raspberry Pi Pico to make a MIDI keyboard which can be used as a plug and play USB device and it worked!!</p> <p>I wrote the code with C and used the TinyUSB library to communicate via USB and it's a really amazing library to work with because it allows you to do wonders with a very high level abstraction. With TinyUSB and Pi Pico you can literally make any kind of USB devices including keyboards, game consoles and even USB flash drives. Pretty amazing right?</p> <p>However, the learning resources for TinyUSB are still really low specially when it comes to TinyUSB + Pi Pico. So I wrote an article series on medium about this project and they are first-page ranked on Google Search too.</p> <p>If you like to read the articles, please follow the links below.</p> <p><strong>(1) Setup, Build and Flash Your First Raspberry Pi Pico Program with C/C++</strong>: <a href="https://medium.com/cooking-with-raspberries/setup-build-and-flash-your-first-raspberry-pi-pico-program-with-c-c-730373c01eca" rel="noopener noreferrer">https://medium.com/cooking-with-raspberries/setup-build-and-flash-your-first-raspberry-pi-pico-program-with-c-c-730373c01eca</a></p> <p><strong>(2) Getting Started with Raspberry Pi Pico and TinyUSB.</strong><br> <a href="https://medium.com/cooking-with-raspberries/getting-started-with-raspberry-pi-pico-and-tinyusb-b45e0ab53783" rel="noopener noreferrer">https://medium.com/cooking-with-raspberries/getting-started-with-raspberry-pi-pico-and-tinyusb-b45e0ab53783</a></p> <p><strong>(3) Turn your old digital keyboard into a USB MIDI keyboard with RPI Pico and TinyUSB.</strong><br> <a href="https://medium.com/cooking-with-raspberries/turn-your-old-digital-keyboard-into-a-usb-midi-keyboard-with-rpi-pico-and-tinyusb-28d4bfbae39e" rel="noopener noreferrer">https://medium.com/cooking-with-raspberries/turn-your-old-digital-keyboard-into-a-usb-midi-keyboard-with-rpi-pico-and-tinyusb-28d4bfbae39e</a></p> <p>Also I made a simple video as a demo. As I am not very good at playing the keyboard it doesn't sound good but the keyboard works so well :) </p> <p> <iframe src="https://www.youtube.com/embed/txL9yLeklfU"> </iframe> </p> <p>This is my very first post in this amazing community and hope you guys will like my project. </p> <p>Thank you so much for reading.</p> <p>Happy Building.<br> Chamodh</p> raspberrypi usb
