Detailed Description

LEON2 Board Support Package.

Macro Definition Documentation

◆ GRETH_MEM_LOAD

#define GRETH_MEM_LOAD ( addr )

Value:

leon_r32_no_cache((uintptr_t) addr)

Function Documentation

◆ bsp_idle_thread()

void * bsp_idle_thread ( uintptr_t ignored )

Optimized idle task.

This idle task sets the power mode to idle. This causes the processor clock to be stopped, while on-chip peripherals remain active. Any enabled interrupt from a peripheral or an external interrupt source will cause the processor to resume execution.

To enable the idle task use the following in the system configuration:

#include <bsp.h>
 
#define CONFIGURE_INIT
 
#define CONFIGURE_IDLE_TASK_BODY bsp_idle_thread
 
#include <confdefs.h>

◆ console_inbyte_nonblocking()

int console_inbyte_nonblocking ( int port )

This method polls the specified port for an input character. console port.

Parameters

[in] port is the input port

Returns: This method returns the character read of -1 if there is no data.
