Function Documentation

void KEYBOARD_AIN_NotifyChange	(	u32	pin,
		u32	pin_value
	)

This function should be called from AIN_NotifyChange in app.c

In addition it should be called periodically from a task to handle the reduced bandwidth function.
See also apps/controllers/midibox_kb_v1/src/app.c

     // update AINs with current value
     // the keyboard driver will only send events on value changes
     {
       int pin;
 
       for(pin=0; pin<8; ++pin) {
        KEYBOARD_AIN_NotifyChange(pin, MIOS32_AIN_PinGet(pin));
       }
     }

Here is the call graph for this function:

u8 KEYBOARD_ConnectedNumGet

(

void

)

Returns number of connected keyboards

s32 KEYBOARD_ConnectedNumSet

(

u8

num

)

Sets number of connected keyboards

s32 KEYBOARD_Init

(

u32

mode

)

Initialize the keyboard handler

Parameters:

	mode	== 0: init configuration + runtime variables
	mode	> 0: init only runtime variables

void KEYBOARD_Periodic_1mS

(

void

)

This function should be called periodically (each mS) to check for pin changes

Here is the call graph for this function:

void KEYBOARD_SRIO_ServiceFinish

(

void

)

This hook is called after the shift register chain has been scanned

Here is the call graph for this function:

void KEYBOARD_SRIO_ServicePrepare

(

void

)

This hook is called before the shift register chain is scanned

Here is the call graph for this function:

s32 KEYBOARD_TerminalHelp

(

void *

_output_function

)

Returns help page for implemented terminal commands of this module

Here is the call graph for this function:

s32 KEYBOARD_TerminalParseLine	(	char *	input,
		void *	_output_function
	)

Parser for a complete line

Returns:

> 0 if command line matches with UIP terminal commands

Here is the call graph for this function:

s32 KEYBOARD_TerminalPrintConfig	(	int	kb,
		void *	_output_function
	)

Keyboard Configuration (can also be called from external)

s32 KEYBOARD_TerminalPrintDelays	(	int	kb,
		void *	_output_function
	)

Keyboard Configuration (can also be called from external)
