stm32f0_tim_pwmcapture_block

What can be configured?

Configuration item	Selectable option/ Value	Description
Timer	(Select time module for available list)	List of timers available depending on MCU part
Capture pin	(Select Pin for capture)	Note: available pin for selection depending on selected timer module.
Capture Pin Type (Pull-Up/Pull-Down)	None \| Pull Up \| Pull Down	Pin type for select capture pin
Capture Edge	Rising \| Falling
Capture data type	double \| single	Recommended use "single" for data type, to optimize math calculation code.
Sample time (sec)	(sampletime)	Specify block sample time

Capture Edge

Output port

1. READY

Return status of PWM capture operation, value is non-zero when data is ready.

2. +Width (sec)

Positive pulse width value, in unit of seconds.

3. +Duty (%)

Positive duty cycle value, in percentage.

4. Frequency (Hz)

PWM frequency, in unit of Hz.

When to use this block?

Use this block when input signal is PWM, to analyze its frequency and duty cycle. Maximum input frequency should lower than 10kHz, and minimum is 0.33Hz.

Note

1. Selected timer module must not conflicted with other timer function.

2. Selectable pin for capture the input signal (available pins depending of selected Timer module).

3. The block use input capture interrupt approach, it may effect to overall system timing if input frequency too High (Lower than 10kHz is recommended).
