STM32 Programming: Read PWM Input signal for Radio controller

[@orides5976]

Thank you for giving us your time and your work to teach us the joy of modern technology.

[@steppeschool3629]

It's my pleasure

LOVE YOUR WORKS ,KEEP WHAT YOU ARE DOING MAN

[@steppeschool3629]

Thanks, Much appreciated!

Hi Yerke ,can i suggest a tutorial video,so its nice to read pwm signal but its lots of cable when you want to read 10 channels,so can you make a tutorial for reading tis values with ppm encoder

[@steppeschool3629]

Thanks for the suggestion. I will definitely check it out.

@@steppeschool3629 hi i figured we dont need the encoder the receiver itself has a ppm pin,when we set the controller it produces ppm signal for each channel,please make a video please

I am an intermediate Industrial Automation engineer from Tashkent and Working one of the biggest pharmaceutical company in Tashkent, 4th year bachelor degree student. I started to do some projects like, I designed HMI for Suppository Machine .Now I am obsessed with HMI and PLC programming to Tablet making machine and soon finish it. What I want to say is, I really want to learn STM32 and Circuit design , and will watch all your videos, !!!is it possible to contact with you ? I need some advice , thank you very much

[@steppeschool3629]

Thanks for your interest👍. If you have questions, you can write to my email [e-mail]. For STM32 programming, I have an online course in STM32 Programming that you can find at this link: www.steppeschool.com/courses/stm32-programming-course Good luck with your projects!!

Hii can you use stm32f030 to read ppm and work with servo pwm?

[@farziverse4209]

I think HAL_TIM_IC_CaptureCallback is wrongly mentioned as a fn which calculates the pulse width. It just detects the rising and falling edges of the PWM signal. You need to change its CCER Register Value to make it detect the signal

wdym? isn’t that what he said in the video?

[@MạnhPhạmTiến-y8s]

hi, can you tutorial read muti-RC Channel?

[@steppeschool3629]

Hi, you can use multiple timers to read several RC-channels. It should be very similar to what I did in the video.

[@MạnhPhạmTiến-y8s]

@@steppeschool3629 yes, but other timers just 16 bit and timer overflow occurs. Do you know how to fix this?

[@offensivebias3965]

Hi can you make a video on Read PWM Input signal for Radio controller but wtih multiple channel, also if you have something like that already can you send me a link of it .

[@steppeschool3629]

Hi, you can configure other timers exactly as I did on the video, and you will end up with multiple channels. It is relatively easy to do. Tell me if you have problems with that

@@steppeschool3629 need help on that i have a FS 6 channel receiver so for that we need 6 timers??

Thanks for the comment. What exactly are you asking?

Hi i have copied your code and debug works fine no errors , but when i try to do live expressions it shows , failed to evaluate expression , btw im using mac m1 not sure if this cause the problem , any idea how to fix this ? , please help tnx in advance

[@steppeschool3629]

Hi, variables that you want to see in real time, are they global? LIve expressions can be used only for global variables.

[@offensivebias3965]

@@steppeschool3629 Hi tnx for the reply, turns out i made a mistake on this part mine is duty_cycle = 10000 * HAL_TIM_ReadCapturedValue(htim, TIM_CHANNEL_2) ; capture_value; should be duty_cycle = 10000 * HAL_TIM_ReadCapturedValue(htim, TIM_CHANNEL_2) / capture_value;

Hello dear Master, are you from Uzbekistan? if so , do you have a school in Tashkent
