Detailed Description

Support for stdin/stdout using UART.

Linking this library or calling pico_enable_stdio_uart(TARGET ENABLED) in the CMake (which achieves the same thing) will add UART to the drivers used for standard input/output

Function Documentation

◆ stdin_uart_init()

void stdin_uart_init ( void )

Explicitly initialize stdin only (no stdout) over UART and add it to the current set of stdin drivers.

This method sets up PICO_DEFAULT_UART_RX_PIN for UART input (if defined) , and configures the baud rate as PICO_DEFAULT_UART_BAUD_RATE

◆ stdio_uart_init()

void stdio_uart_init ( void )

Explicitly initialize stdin/stdout over UART and add it to the current set of stdin/stdout drivers.

This method sets up PICO_DEFAULT_UART_TX_PIN for UART output (if defined), PICO_DEFAULT_UART_RX_PIN for input (if defined) and configures the baud rate as PICO_DEFAULT_UART_BAUD_RATE.

Note: this method is automatically called by stdio_init_all() if pico_stdio_uart is included in the build

◆ stdio_uart_init_full()

void stdio_uart_init_full	(	uart_inst_t *	uart,
		uint	baud_rate,
		int	tx_pin,
		int	rx_pin
	)

Perform custom initialization initialize stdin/stdout over UART and add it to the current set of stdin/stdout drivers.

Parameters

uart	the uart instance to use, uart0 or uart1
baud_rate	the baud rate in Hz
tx_pin	the UART pin to use for stdout (or -1 for no stdout)
rx_pin	the UART pin to use for stdin (or -1 for no stdin)

◆ stdout_uart_init()

void stdout_uart_init ( void )

Explicitly initialize stdout only (no stdin) over UART and add it to the current set of stdout drivers.
