Function Documentation

TM_PWM_Result_t TM_PWM_InitChannel	(	TM_PWM_TIM_t *	TIM_Data,
		TM_PWM_Channel_t	Channel,
		TM_PWM_PinsPack_t	PinsPack
	)

Initializes channel used for specific timer.

Parameters

*TIM_Data	Pointer to struct with already initialized timer for PWM
Channel	Select channel you will use on specific timer. This parameter can be a value of TM_PWM_Channel_t
PinsPack	Select which pinspack you will use for pin. This parameter can be a value of TM_PWM_PinsPack_t

Return values

TM_PWM_Result_t TM_PWM_InitTimer	(	TIM_TypeDef *	TIMx,
		TM_PWM_TIM_t *	TIM_Data,
		double	PWMFrequency
	)

Initializes specific timer for PWM capability.

Parameters

*TIMx	Pointer to selected timer, you want to use for PWM
*TIM_Data	Pointer to blank TM_PWM_TIM_t structure. Here will init function save all data for specific timer
PWMFrequency	Select custom frequency for PWM

TM_PWM_Result_t TM_PWM_SetChannel	(	TM_PWM_TIM_t *	TIM_Data,
		TM_PWM_Channel_t	Channel,
		uint32_t	Pulse
	)

Sets PWM value for specific timer and channel.

Parameters

*TIM_Data	Pointer to struct with already initialized timer for PWM
Channel	Select channel you will use on specific timer. This parameter can be a value of TM_PWM_Channel_t
Pulse	Pulse, to be set for compare match

Return values

TM_PWM_Result_t TM_PWM_SetChannelMicros	(	TM_PWM_TIM_t *	TIM_Data,
		TM_PWM_Channel_t	Channel,
		uint32_t	micros
	)

Sets PWM value for specific timer and channel with pulse high time feature.

Note: You have to specify amount of micro seconds pulse will be high for specific timer and channel. This method is not so good on PWM large than 100k, because you cannot set nice and correct settings, with microseconds accuracy. It is perfect, and was designed for low frequencies, eg. use with servos, where you have exact amount of time for servo's rotation.

Parameters

*TIM_Data	Pointer to struct with already initialized timer for PWM
Channel	Select channel you will use on specific timer. This parameter can be a value of TM_PWM_Channel_t
micros	Microseconds for pulse high on PWM. Cannot be large than timer period in micros. PWM 1kHz = Timer period = 1000000 / 1000 = 1000us. This parameter can not be greater than 1000us in this case.

TM_PWM_Result_t TM_PWM_SetChannelPercent	(	TM_PWM_TIM_t *	TIM_Data,
		TM_PWM_Channel_t	Channel,
		float	percent
	)

Sets PWM value for specific timer and channel with percentage feature.

Parameters

*TIM_Data	Pointer to struct with already initialized timer for PWM
Channel	Select channel you will use on specific timer. This parameter can be a value of TM_PWM_Channel_t
percent	Percentage from 0 to 100, to set PWM duty cycle
