Hi, I use a STM32 Nucleo-F412ZG and I have 4 motors with 4 quadrature encoders. It seems to working fine whatever the mode configured. This means that we are using an encoder with two channels (phases). STM32定时器编码器模式（Encoder Mode） CubeMX配置过程 Feb 17, 2020 · But, for Encoder Mode, the counter register is clocked by the encoder pulses. We will use a rotary encoder to demonstrate that how to read the encoder ticks using STM32Cube IDE and HAL libraries. Then, we will discuss how to configure the timer in encoder mode. 6. It didn't work for me. You switched accounts on another tab or window. g. The timer I used was a 16-bit timer, and I ended up with something like this: Nov 16, 2017 · Posted on November 16, 2017 at 15:37 Hi. To monitor motor position I want to use a General Purpose Timer (16bits) in Encoder Mode. For a given PWM switching frequency, this mode reduces the acoustic noise . May 7, 2024 · Single timer for encoder on Channel 1 & 2 and PWM generation on Channel 3? in STM32 MCUs Motor control 2024-10-07; How to set the quadratic encoder in 2x mode under MotorControl? in STM32 MCUs Motor control 2024-10-01; STM32G431 Encoder Mode Issue in STM32 MCUs Products 2024-09-10; STM32L431 TIM2 Rotary Encoder in STM32 MCUs Products 2024-08-27 Nov 20, 2022 · Source Code:https://www. I want the interrupt of TIM5 be triggered every time the period of timer overflows and goes to 0. And the CPU can access the counter register whenever needed. Between the pulses (call it the silent time), you also need a good prediction for speed. My TIM2 is in Encoder mode, and I give two external signals from my incremental encoder to TIM2_CH1 and TIM2_CH2. bjjtj jvovmj hbsw wwnh uzjx gfrzd qhkqq vgdvib djjqq wavysmz
