Function Documentation

mios32_mf_config_t MIOS32_MF_ConfigGet ( u32  mf  ) 

returns the MF configuration

Parameters:
[in] mf motor number (0..MIOS32_MF_NUM-1)
Returns:
mf_config.deadband
mf_config.pwm_period
mf_config.pwm_duty_cycle_up
mf_config.pwm_duty_cycle_down
s32 MIOS32_MF_ConfigSet ( u32  mf,
mios32_mf_config_t  config 
)

This function configures various MF driver parameters.
see http://www.ucapps.de/mbhp_mf.html for detailed informations about these parameters.

Parameters:
[in] mf motor number (0..MIOS32_MF_NUM-1)
[in] config a structure with following members:

  • mf_config.deadband
  • mf_config.pwm_period
  • mf_config.pwm_duty_cycle_up
  • mf_config.pwm_duty_cycle_down
Returns:
-1 if motor doesn't exist
s32 MIOS32_MF_FaderDirectMove ( u32  mf,
mios32_mf_direction_t  direction 
)

direct control over the motorfader

Parameters:
[in] mf motor number (0..MIOS32_MF_NUM-1)
[in] direction is MF_Standby, MF_Up or MF_Down
Returns:
-1 if motor doesn't exist

Here is the call graph for this function:

s32 MIOS32_MF_FaderMove ( u32  mf,
u16  pos 
)

set target position and move fader

Parameters:
[in] mf motor number (0..MIOS32_MF_NUM-1)
[in] pos motorfader position (resolution depends on the used AIN resolution, usually 12bit)
Returns:
-1 if motor doesn't exist

Here is the call graph for this function:

s32 MIOS32_MF_Init ( u32  mode  ) 

Initializes motorfader driver

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

Here is the call graph for this function:

s32 MIOS32_MF_SuspendGet ( u32  mf  ) 

returns the suspend state of the motor

Parameters:
[in] mf motor number (0..MIOS32_MF_NUM-1)
Returns:
-1 if motor doesn't exist
1 if motor suspended
0 if motor not suspended
s32 MIOS32_MF_SuspendSet ( u32  mf,
u8  suspend 
)

activates/deactivates suspend mode of motor
(function used by touchsensor detection)

Parameters:
[in] mf motor number (0..MIOS32_MF_NUM-1)
[in] suspend 1 to enable, 0 to disable suspend
Returns:
-1 if motor doesn't exist
s32 MIOS32_MF_Tick ( u16 ain_values,
u16 ain_deltas 
)

Called from AIN DMA interrupt whenever new conversion results are available

Parameters:
[in] *ain_values pointer to current conversion results
[in] *ain_deltas pointer to differences between old and new results
Returns:
-1 on errors
>= 0: mask of 16 "changed" flags which should not cleared (if "changed" flag set, the AIN driver will propagate a new conversion value to the application hook)
Note:
shouldn't be called directly from application
s32 MIOS32_MF_TouchDetectionReset ( u32  mf  ) 

this function resets the software implemented touch detection, so that the fader is repositioned regardless if it is currently moved or not

Parameters:
[in] mf motor number (0..MIOS32_MF_NUM-1)
Returns:
-1 if motor doesn't exist
