The waveform is not displayed when using the STM32F4xx Encoder block

Hello everyone,

I’m currently working on a project to control the speed of a DC motor by embedding code from MATLAB into an STM32F4xx. However, when I started using the Encoder block, it didn’t display any waveform or value during execution — it only shows a constant level of 0.

I’ve already checked the wiring connections and verified that the timer configured for the encoder function is working properly.

I would really appreciate any help or suggestions to solve this issue.

Thank you!

Kindly contact the Technical Support and share the relevant files pertaining to the project like simplified/reduced Simulink model and the IOC file. It will be helpful in reproducing the issue faced by you.
