Pico-PIO-USB

USB host/device implementation using PIO of raspberry pi pico (RP2040).

You can add additional USB port to RP2040.

Demo

host_hid_to_device_cdc.c which print mouse/keyboard report from host port to device port's cdc. TinyUSB is used to manage both device (native usb) and host (pio usb) stack.
usb_device.c is a HID USB FS device sample which moves mouse cursor every 0.5s. External 1.5kohm pull-up register is necessary to D+ pin (Default is gp0).
