Function Documentation

s32 AINSER_DeadbandGet ( u8  module  ) 
Returns:
the deadband which is used to notify changes
< 0 on error
s32 AINSER_DeadbandSet ( u8  module,
u8  deadband 
)

Sets the difference between last and current pot value which has to be achieved to trigger the callback function passed to AINSER_Handler()

Returns:
< 0 on error
s32 AINSER_EnabledGet ( u8  module  ) 
Returns:
the enable mask for modules which should be scanned
s32 AINSER_EnabledSet ( u8  module,
u8  enabled 
)

Sets the enable mask for modules which should be scanned

s32 AINSER_Handler ( void(*)(u32 module, u32 pin, u32 value)  _callback  ) 

This function should be periodically called to scan AIN pin changes.

A scan of a single multiplexer selection takes ca. 50 uS on a LPC1769 with MIOS32_SPI_PRESCALER_8

Whenever a pin has changed, the given callback function will be called.
Example:

   void AINSER_NotifyChanged(u32 pin, u16 value);
Parameters:
[in] _callback pointer to callback function
Returns:
< 0 on errors

Here is the call graph for this function:

s32 AINSER_Init ( u32  mode  ) 

Initializes AINSER driver Should be called from Init() during startup

Parameters:
[in] mode currently only mode 0 supported
Returns:
< 0 if initialisation failed

Here is the call graph for this function:

s32 AINSER_MuxedGet ( u8  module  ) 
Return values:
0 if 1-to-8 multiplexers disabled for the given module
1 if 1-to-8 multiplexers enabled for the given module (default)
s32 AINSER_MuxedSet ( u8  module,
u8  muxed 
)

Enables/disables the 1-to-8 multiplexer handling.
Use muxed=0 for AINSER8 module, and muxed=1 for AINSER64 module (default)

s32 AINSER_NumModulesGet ( void   ) 
Returns:
the number of modules which are scanned
s32 AINSER_NumModulesSet ( u8  num_modules  ) 

Sets the number of modules which should be scanned

Returns:
< 0 on error (e.g. unsupported number of modules)
s32 AINSER_NumPinsGet ( u8  module  ) 
Returns:
the number of AIN pins per module which are scanned
s32 AINSER_NumPinsSet ( u8  module,
u8  num_pins 
)

Sets the number of AIN pins per module which should be scanned

Returns:
< 0 on error (e.g. unsupported number of pins)
s32 AINSER_PinGet ( u8  module,
u8  pin 
)
Returns:
the AIN pin value of the given module and pin
< 0 if wrong module or pin selected!
s32 AINSER_PreviousPinValueGet ( void   ) 
Returns:
the previous value of the pin which has triggered the NotifyChanged hook.
Only valid when function is called from this hook!
