Detailed Description

Function Documentation

BSP_PWM11_16_Config_Interrupt()

void BSP_PWM11_16_Config_Interrupt ( bool  enable, PWMResetCallback  callback, int  priority  )

extern

Parameters

enable	If enable interrupt set this parameter to true
callback	Specifies the function to be called when the PWM is reset
priority	Interrupt priority. Range (0-15). Here 0 is the highest priority

BSP_PWM11_16_ConfigChannels()

DutyCycleUpdateFnc BSP_PWM11_16_ConfigChannels ( uint32_t  pwmNo, pwm_config_t *  config, int  chCount  )

extern

Parameters

pwmNo	Channel no of the first PWM Channel in the pair (Valid Values 11-16)
*config	Pointer to a pwm_config_t structure that contains the configuration parameters for the PWM channels
chCount	No of channels to be configured with the setting. Max supported value is 3. The value should be counted while skipping even channels. e.g. if pwmNo = 11 and chCount = 2 the PWMs 11 and 13 will be configured with the specified setting while PWM12 will be the inverted version of PWM11

Returns

DutyCycleUpdateFnc Returns the function pointer of the type DutyCycleUpdateFnc which needs to be called whenever the duty cycles of the pair need to be updated

BSP_PWM11_16_ConfigInvertedPairs()

DutyCycleUpdateFnc BSP_PWM11_16_ConfigInvertedPairs ( uint32_t  pwmNo, pwm_config_t *  config, int  pairCount  )

extern

Parameters

pwmNo	Channel no of reference channel is the PWM pair (Valid Values 11-16). Pairs are classified as : CH1 = Reference channel available at pin pwmNo CH2 = Inverted Channel from reference available at pin pwmNo + 1 if pwmNo is odd else pwmNo - 1
*config	Pointer to a pwm_config_t structure that contains the configuration parameters for the PWM pair
pairCount	No of PWM pairs to be configured

Returns

DutyCycleUpdateFnc Returns the function pointer of the type DutyCycleUpdateFnc which needs to be called whenever the duty cycles of the pair need to be updated

BSP_PWM11_16_UpdateChannelDuty()

float BSP_PWM11_16_UpdateChannelDuty ( uint32_t  pwmNo, float  duty, pwm_config_t *  config  )

extern

Parameters

pwmNo	PWM channel to be configured (Valid Values 11-16)
duty	duty cycle to be applied to the channel (Range 0-1 or given in the config parameter)
*config	Pointer to a pwm_config_t structure that contains the configuration parameters for the PWM channel

Returns

float Duty cycle applied in this cycle. May differ from the duty variable if outside permitted limits

BSP_PWM11_16_UpdatePairDuty()

float BSP_PWM11_16_UpdatePairDuty ( uint32_t  pwmNo, float  duty, pwm_config_t *  config  )

extern

Parameters

pwmNo	Channel no of reference channel is the PWM pair (Valid Values 11-16). Pairs are classified as : CH1 = Reference channel available at pin pwmNo CH2 = Inverted Channel from reference available at pin pwmNo + 1 if pwmNo is odd else pwmNo - 1
duty	duty cycle to be applied to the pair (Range 0-1 or given in the config parameter)
*config	Pointer to a pwm_config_t structure that contains the configuration parameters for the PWM pair

Returns

float Duty cycle applied in this cycle. May differ from the duty variable if outside permitted limits
