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
