Hi, I am using STM32F407 for my PMSM vector control project. And i need to determine the current position of motor for vector control. So I use TIM3 Encoder MODE (x4) and ı have 360 PPR (pulse per revolution) encoder. I set the ARR value 1439 (4*36...

I removed the transistor and tested the pins with diode measurment as you said. There is short circuit between base-emitter. I am going to change with proper one. Thank you for your help. I ll give info about the result soon.

Hi Peter, thank you for your reply firstly. I tried to draw circuit and share below. This is a flyback converter as you said. I tested all diodes and there is no short circuit. Fuse is also OK, there is connection. I also measured the DC link voltage...

I have tried to reduce filter. Nothing was changed. Then I observe the encoder signal from oscilloscope and count the pulses. I saw jitter on the A and B signals. The jitter bacuse of the IPMSM magnet. I removed the encoder from the motor. I tried to...

Searching equivalent part of this old ST component

How can ı use the FPU (Floating Point Unit) in STM32F407?

Encoder Mode Counter value is missing in every revolution?
