Raspberry Pi Pico USB-UART Bridge
This program bridges the Raspberry Pi Pico HW UARTs to two independent USB CDC serial devices in order to behave like any other USB-to-UART Bridge controllers.

Raspberry Pi Pico Pinout
UART0:
| Raspberry Pi Pico GPIO | Function |
|---|---|
| GPIO0 (Pin 1) | TX |
| GPIO1 (Pin 2) | RX |
| GPIO2 (Pin 4) | CTS |
| GPIO3 (Pin 5) | RTS |
| GPIO4 (Pin 6) | DTR |
| GPIO5 (Pin 7) | DSR |
UART1:
| Raspberry Pi Pico GPIO | Function |
|---|---|
| GPIO8 (Pin 11) | TX |
| GPIO9 (Pin 12) | RX |
| GPIO10 (Pin 14) | CTS |
| GPIO11 (Pin 15) | RTS |
| GPIO12 (Pin 16) | DTR |
| GPIO13 (Pin 17) | DSR |
Optional Hardware Flow and Line control
Hardware Flow-control (RTS/CTS) is disabled by default, but can be compiled in by running:
cmake -DFLOW_CONTROL .
make
Line control (DTR/DSR) is disabled by default, but can be compiled in by running:
cmake -DLINE_CONTROL .
make
To enable both:
cmake -DLINE_CONTROL -DFLOW_CONTROL .
make
