STM32 Guide #3: PWM + Timers

День тому

This video covers the basics of PWM, and how to implement it with STM32.
STM32 gives you a bit more control than Arduino, but all these extra parameters might be a bit overwhelming at first. This video describes Duty Cycle, Resolution, Frequency, and other things that will help you get started with PWM.
Part 2 will be released eventually.

This is one of the best instructions I have ever had, and I’m a 65 years old EE :-) I can imagine the amounts of time you have spent making these videos. I have played with Arduino for many years, but you are the first to teach me what REALLY goes on behind the IDE. Because of you I’ll start working with STM, and you’ve already given me a flying start. But please don’t stop now ... Again, thanks a lot !

@@MitchDavis2 hi mate how about like this??? Code: htim1.Init.Period = ((PWM_PERIOD_CYCLES) / 2); Code: sConfigOC.Pulse = (uint32_t)(((PWM_PERIOD_CYCLES) / 2) * 0.6); It will working?? So no need set pwmc setphasavoltage, because global pwm duty (pulse) already set max 60%?? Or this will set all tim for 60% sir?? Any idea?? Thank u

This series video is a great help to those who just started using STM32, as well as those who are somewhat familiar with it without being proficient; I am the latter. All tricks learnt in operating the STM32 IDE environment are so valuable that they will save you a lot of time and energy and most importantly, frustration. These tricks and insights are bridging the gap between where I am and where I want to be. I appreciated your generous sharing of knowledge which you at one point had to put in efforts to learn yourself!

@GundamTricks 4 місяці тому

The best beginner-friendly explanation about PWM timers. For some viewers, there might be a bit of misunderstanding. At 9:25, you're using 72 MHz as example (281 kHZ fix typo), and at 19:10, you're using 8 MHz, as shown by the 31 kHz reading on the oscilloscope."

@manfred4283 3 роки тому

Thanks for the video series about STM32. Your explanations are really great. There is a typo in the calculation of the PWM frequency. It is actually 281250 Hz instead of 218250 Hz. Later on the scope shows the right duty cycle but at another frequency. Might be related to the clock configuration. This is a little confusing for beginners like me. But the video still helped me to get the PWM configured.

@peterbraganza3258 2 роки тому

Hey I had a similar confusion with the frequency at the end being about 31kHz. What I think is he used the internal HSI(High speed clock) RC oscillator which gives you a frequency of 8MHz . So when you calculate the frequency of PWM you get 8Mhz/256 = 31kHz. hope this helps! (Note: You can get 72Mhz clock speed from the external crystal oscillator but you have to configure that in the CubeMX clock configuration)
