[ESP32]UART串口使用ESP32里面有3个串口,uart0默认作为log和console输出,我们可以使用uart1和uart2。 它们默认的管脚如下:UARTGPIOUARTGPIOU0_RXDGPIO3U0_CTSGPIO19U0_TXDGPIO1U0_RTSGPIO22U1_RXDGPIO9U1_CTSGPIO6U1_TXDGPIO10U1_RTSGPIO11U2_RXDGPIO16 ...

Got things working? USART0 is different from USART1-4. Be sure to enable clocks: Chip_Clock_EnablePeriphClock(SYSCTL_CLOCK_IOCON); Chip_GPIO_Init(LPC_GPIO);Then: Chip_IOCON_PinMuxSet(LPC_IOCON, Port, Pin, (IOCON_FUNC1 | IOCON_MODE_INACT | IOCON_DIGMODE_EN)); Chip_IOCON_Pin...
