Define Documentation

#define NPL_BASE   0xFF00

CPLD register base address.

On Ethernut 3 the CPLD is selected via NCS2 (GPIO 27), which is configured to 0x21000000 - 0x210FFFFF in the CRT initialization startup file.


Function Documentation

int NplIrqDisable ( IRQ_HANDLER *  irq  ) 

Disable a specified NPL interrupt.

Parameters:
irq Interrupt to disable.
Returns:
0 on success, -1 otherwise.

int NplIrqEnable ( IRQ_HANDLER *  irq  ) 

Enable a specified NPL interrupt.

Parameters:
irq Interrupt to enable.
Returns:
0 on success, -1 otherwise.

int NplRegisterIrqHandler ( IRQ_HANDLER *  irq,
void(*)(void *)  handler,
void *  arg 
)

Register an NPL interrupt handler.

This function is typically called by device drivers, but applications may also implement their local interrupt handlers.

Parameters:
irq Interrupt to be associated with this handler.
handler This routine will be called by Nut/OS, when the specified interrupt occurs.
arg Argument to be passed to the interrupt handler.
Returns:
0 on success, -1 otherwise.

__BEGIN_DECLS void NplUledCntl ( int  status  ) 

Low Level User LED (Green) Access.User LED control routine.

Parameters:
status ULED_ON of ULED_OFF

Activate negated chip select.

Deactivate negated chip select.

int NplUledStatus ( void   ) 

User LED status routine.

Returns:
The ULED Status (ULED_ON or ULED_OFF).
