Raspberry Pi Pico USB-UART Bridge
This is a fork of https://github.com/Noltari/pico-uart-bridge and a pull request which takes too long time to include. Some fixes applied by myself for a successful build.
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 if you build it just with build.sh, but there are other buld scripts:
./build_w_flow_ctrl.sh
Line control (DTR/DSR):
./build_w_line_ctrl.sh
To enable both:
./build_w_line_flow_ctrl.sh
