#define	bsp_getChar()
	Map standard character input to the physical UART.

Functions
void	bsp_init ()
	Initialize Board Support Package Peripherals.

Macro Definition Documentation

bsp_getChar

#define bsp_getChar

(

)

#include <bsp.h>

Value:

uart_read(&uart0)

Map standard character input to the physical UART.

Note

If hardware UART is present, these macros will use the uart_read functions to perform I/O through the physical UART. If hardware UART is not present, these macros will be defined as safe dummy macros that do nothing return 0 (for getChar).

It is recommended to use standard scanf for better functionality and compatibility with the C library, which are also mapped to the physical UART if it exists.

bsp_putChar

#define bsp_putChar

(

c

)

#include <bsp.h>

Value:

uart_write(&uart0, c)

Map standard character output to the physical UART.

Note

If hardware UART is present, these macros will use the uart_write functions to perform I/O through the physical UART. If hardware UART is not present, these macros will be defined as safe dummy macros that do nothing (for putChar).

It is recommended to use standard printf for better functionality and compatibility with the C library, which are also mapped to the physical UART if it exists.
