STM32 drives EC11 encoder

Using the Tim encode mode of STM32F446RE to accept EC11 encoder data can distinguish between forward and reverse? How can this be achieved using the LL library?

You can configured the TIM1 in encoder mode interface, counting on TI1 and TI2.

The counting direction corresponds to the rotation direction of the connected

sensor. So you can distinguish between forward and Backward.

The LL TIM_Encoder example is not available in STM32CubeF4 package with STM32F446 MCU, but you can get inspired from HAL TIM_Encoder example.

It seems that CubeIDE can use the LL library to generate TIMers in Encode mode?

Hi @YLi.13​ ,

Yes, you can use the STM32cubeIDE to generate Tim_Encoder project with the LL library.

After configuring your project with STM32cubeIDE, you can click at project manager/advanced settings and choose to use LL drivers in driver selector as shown in the below figure.

And I found in the STM32F4 series LL library manual that it can drive the Encode mode of TIMer, so may I know how to understand "The LL TIM_Encoder example is not available in STM32CubeF4 package with STM32F446 MCU, but you can get inspired from HAL TIM_Encoder example."?

So I use the function LL_ TIM_ The Counter value obtained by GetCounter will not only increase but also decrease based on the output of encoder channel A and channel B, right?
