TIM PWM Generation Block Description

This block enables PWM signal generation using timers in STM microcontrollers.

TIM PWM Generation block

Inputs

Input Name	Type	Description
*CH [%]**	uint8	The duty cycle percentage of the PWM signal for the given channel. The value must be within the range of 0 to 100, where 0 represents no signal output and 100 represents full PWM signal duty cycle.
Period [sec]	uint16	Conditional input The PWM signal period value in microseconds. The availability of this input port depends on the Enable input period parameter.

CH* [%] – PWM channel inputs, where * denotes the specific channel number (e.g., CH1 [%], CH2 [%], etc.).

This block has no outputs.

Parameter	Description
Timer	The timer number designated to generate hardware interrupts.
Timer clock (MHz)	The core operational frequency of the timer clock in MHz.
Prescaler	The hardware prescaler value for the timer.
Enable input period	Enables an input port that allows dynamically setting the PWM signal period.
PWM Period (sec)	Conditional Parameter The fixed period value for the timer counter. This parameter is only accessible when the Enable input period option is disabled.
Show timer counter	Conditional Parameter Displays comprehensive internal details of the timer counter registers. This parameter is only accessible when the Enable input period option is disabled.
Enable channel	Configures the operational mode for individual PWM channels: `Disable` – channel is turned off. `CH` – channel is enabled with standard/positive polarity. `CHN` – channel is enabled with complementary/negative polarity. `CH* CH*N` – channel is enabled with both standard and complementary outputs active.

TIM PWM parameters

No.	Name	Path	Setting	Description
1	Clock Source	Pinout & Configuration > TIM* > Mode > Clock Source	`Internal Clock`	Selects the active operational clock source for the timer.
2	Global interrupt / Update interrupt	Pinout & Configuration > TIM* > NVIC Settings > Global interrupt / Update interrupt	`Enabled`	Enables hardware interrupts for the timer. Depending on the timer type, a Global or Update interrupt channel is available; one of these options must be enabled.
3	Channel* Configuration	Pinout & Configuration > TIM* > Mode > Channel*	`CH` `CHN` `CH* CH*N`	Selects the generation method of the PWM signal for the specific channel. This setting must explicitly match the selection made in the Enable channel block parameter.

CH* – the PWM channel identifier where * denotes the channel index number (e.g., CH1, CH2, etc.).
