This video is for very beginners without code explanation. I have made another video about this topic with bit more details in video no - 70 in this channel kzfaq.info/get/bejne/ncVllZaT1r3IkmQ.html

It works very well. Thanks for this tutorial. I subscribed in case you make new videos, you stopped for 4 months, it's a shame. I hope you will be able to resume because I love your work. Best wishes !

You setting the prescaler and ARR but you don't even explain why you using those values

I'm looking for the library to PHOTO SENSOR VEML6040 RGBW 16-BITS I2C, I would like to know where I can find the libraries to use in CubeIDE. Could you please help me? thank you so much, yours videos are helping me a lot.

I am sorry I don’t have VEML6040 with me at the moment.

Thanks a lot. It is really simple. How can I make pwm with adjustable frequency and duty cycle?

@NizarMohideen 2 жыл бұрын

In this example I wanted to have 100Hz with 0-100% variable duty cycle. How I did is: Clock frequency = 8000000Hz I divided it by 128 (prescaler) and then divided it again 625 (Counter period) to get 100Hz Follow this to get different frequency as you wish. I am adjusting duty cycle on the fly using __HAL_TIM_SET_COMPARE in the for loop from 0 (0%) - 625 (100%)( Counter period) Note : prescaler is always one less 128 is 128-1 =127

@NizarMohideen 2 жыл бұрын

If you want to set the frequency on the fly you can use __HAL_TIM_SET_AUTORELOAD as I did in video kzfaq.info/get/bejne/sN1hoLSGrpjXg4E.html

@@NizarMohideen isn't it the other way around? The prescaler is the same but the counter period is -1 because it starts at 0?

@NizarMohideen 2 жыл бұрын

You can use other way round, it will generate pwm. But the counter period needs to be more than 1 (one) in order to have variable pulse width from 0-100%

Why i can't use this code with L293 motor shield? I've been trying to control the speed of DC motor 3V-6V. Please, help

@NizarMohideen 2 жыл бұрын

Hi Andrey, I don’t have L293 with me. I have done L298N motor control in video no 20 in this channel. I hope it gives you a stepping stone

What is doing __HAL_TIM_SET_COMPARE() Functions?

@NizarMohideen 2 жыл бұрын

Hi there, Since we set Configuration → Parameter Settings → Counter Period 625, we can change Pulse from 0 to 625. 0 being 0% and 625 being 100% pulse width. __HAL_TIM_SET_COMPARE() is a macro to set the pulse on the fly.
