| UART bridge |
| |
| Bridges data from two serial devices, for example a USB CDC-ACM serial port |
| and an hardware UART. |
| |
| The device node must have exactly two child nodes for the two devices to be |
| bridged together. Example configuration: |
| |
| uart-bridge { |
| compatible = "zephyr,uart-bridge"; |
| usb { |
| device = <&cdc_acm_uart_ec>; |
| transfer-size = <64>; |
| }; |
| uart { |
| device = <&uart4>; |
| transfer-size = <1>; |
| }; |
| }; |
| |
| compatible: "zephyr,uart-bridge" |
