Artery PWM

Generation of a PWM signal at the output of the microcontroller timer.

blockType: CFunction

artery pwm

Path in the library:

/Interfaces/Targets/Artery/Artery PWM

Description

To work with the block, install/update the support package. equipment.

Block Artery PWM It is used to generate a PWM signal on a given timer channel. In the first step, the timer starts in PWM mode. The value at the input of the block determines the filling factor (borehole).

Configuring the AT32 Workbench

  1. In AT32 Workbench, select the desired timer (TMR1–TMR14, TMR20).

  2. Select the timer channel and set it to PWM mode A:

  3. Configure the PWM parameters in Counter Settings:

    • Divider value (PSC) — divider;

    • Period Value (ARR) — PWM period (determines the resolution of the borehole).
