We start by importing libraries, including the CircuitPython USB HID library to allow our Pico to emulate a USB device. Then we import elements from the Adafruit HID library that we just installed in our “lib” folder. We need both the keyboard and keycode elements, and we are defining our...

Native USB supported by every OS - can be used in Arduino or CircuitPython as USB serial console, Keyboard/Mouse HID, even a little disk drive for storing Python scripts. (ATtiny85 does not have native USB) Can be used with Arduino IDE or CircuitPython Built in green ON LED Built in red...
These examples will use the TSL2591 lux sensor breakout. The first thing you'll want to do is get the sensor connected so your board has I2C to talk to. Wire It Up You'll need a couple of things to connect the TSL2591 to your board. The TSL2591 comes with STEMMA QT / QWIIC conne...
assembles a report and then passes it back to the host computer. You can see examples of HID devices driversin the adafruit_hidlibrary. And the following pages in this guide will give you several examples of custom HID devices and drivers which you can just copy, or adapt for your own ...
Notice that to enable VENDOR on ESP32-S2, we had to give up HID. There may be platforms that can have both, or even all three. Implementation Notes CircuitPython uses the tinyusb library. The tinyusb library already has support for WebUSB serial. The tinyusb examples already include a "...
Boards that do not support the USB Workflow should be clearly marked. If you choose not to meet these requirements, then we ask you call your version of CircuitPython something else (for example, SuperDuperPython) and not use the Blinka logo. You can say it is "CircuitPython-compatible" if...
Some CircuitPython devices like ESP32-S2 based ones, do not have enough USB endpoints to enable all USB functions, so USB MIDI is disabled by default. To enable it, the easiest is to disable USB HID (keyboard/mouse) support. This must be done in boot.py and the board power cycled.# ...
