Hi, I have been using STM-STUDIO-STM32 for moitoring the real time variable while motor running without disturbing the program. MCU used - Stm32F103c8t6 Debugger used - st-link v2 Software used - Stm-stdio - The stm-stdio is get stopped while deb...

Hello friends, i want to read ADC value for particular time. That is, to read the analog value during the middle time of every pwm signal. Triggering ADC via timer.I had generated pwm signal with 50% duty cycle in center align mode so that we could e...

Hi, i am trying to control bldc motor sinusoidally. I completed with 6 step commutation. I asked help in stm32 forum recent, but none helped. I have learned something in sinusoidal bldc control. FIrstly i implemented spwm using sine LUT (say 256 val...

Hi friends,I think my question will repetitive for you guys (in stm-forum) . Actually sorry for that. I have driven a bldc motor with square wave commutation. Which is basically a simple and easy technique. And i have controlled the bldc motor (in s...

I am developing bldc drives using stm32f103c8t6 MCU. And by using inverter circuit we drive the bldc motor using stm32. Block diagram of drive is shown belowUsing register language, we coded logically for 6 step commutation. And that works fine.But ...

I have tried that TDK but cant able to get the output at the middle of the pwm. Because by using External trigger the adc will measure at the beginning.

Yes TDK I had tried that also. Which work ok, But I want to trigger the adc using timer as well as in dma. That will the efficient right. Thank you for response. Could you help and give a solution.

THank you for your response . Ok piranha what you are saying is, running bldc motor under open loop sinusoidal configuration is accurate and will consume more current. Now i will try to synchronize the hall sensor data (RPM) with sin table. Can you g...

Guys i just ask a kind of help about sinusoidal control topology. At Least say YES or NO, so that i can go different solution.

Bud · 2019-12-17

No no.. Actually i want to enable and disable fastly without any time gap, but when i enable and disable frequency it doesn't works. So by giving some mill-sec delay, it works properly. Any how ok thank-you for your response friend.
