STM32 ADC MULTI CHANNEL without DMA || HAL || Poll 

First of all, thank you. There are a lot of STM32 related RU-vid broadcasts, but it was hard to see normal movements. So I think this RU-vid broadcast is the best.

I was also having problems using dma and doing things in my while loop. DMA will just take over. I could not even end the dma or the adc or the adc in my while loop. So, yes, it was not even getting to the while loop. For polling with multiple channels I start the conversion once and the software converts the 3 channels in a sequence. I only have to poll the EOC bit then save the data for each of the 3 conversions.. I only do the setup of the channels once. I am using a nucleo32 board with STM32L412KB chip. It is the size of an arduino nano footprint but runs at 80MHz and has 40Kbytes of ram, and I think 128Kbytes of ROM, crazy specs compared to AVR 328p. Thank you for your videos. I think this is the best channel on the stm32 on youtube.

Yeah! It's alive, thanks brother!

Note that the maximum ADC clock is 36 MHz, refer to the datasheet of your microcontroller.

thank you, greetings from Indonesia

3:30 why to remove the automatic configuration that STM32 does in the being of the program execution? That kind gets undone as soon as I regenerate the code.

Thank you. 👍

gracias exactamente lo que buscaba!

Thank u for every videos

I am using stm32f030k6t6, the adc configuration mode is different, whatever i done to read a joystick module to control 2 servos it ends with failure, I hope you make a video to explain how to configure it 😢

On Texas instrument is way easier.. i mean, you just set the adc steps and then it does what you want.. instead of relying on dma that adds additional overhead time..

Hey, which Nucleo board is the best among, F446, L476, L496 And, which is the best cortex m7 board under a budget of $50. Can you also suggest some discovery board

Thank you

hi, thanks for the video. I got it working on my blackpill but getting big fluctuations in the live expressions. I am trying to run three voltage meters on a single adc channel w a touch gfx display and the progress bars keep flikering. how to keep the input steady?

Hi! I'm new to STM32. Can you do a tutorial on how to use IR sensor on STM32F1 without any ST-LINK etc? Thank you very much!

Thank you :)

why have you set the different Sampling Time for each channel, could I possible choose the same sampling time

Eres el mejor, I love u

Thank you so much for this! I have a question, how can you call the HAL functions in drop down menu like in @6:13 when you're halfway through typing the name? Would be a great help!

Thank you very much for sharing knowledge with us. code worked nicely...

Make video on ADC oversampling

Hi, I try your concept with stm32 bluepill fir adc continuous conversion without dma it run well but i am not getting the stability for adc as i am using pot for pins but it showning a variation and that is very wide i.e 3204 to 4095 so suggest what could be done here

how to trigger multiple channels by using timer without DMA

Thanks for your tutorial. I managed to get it working in my application, but... Why do you modify the MX generated code so drastically (requiring to reedit the MX_ADC1_Init() function everytime you run another MX session. Does the generated MX code not work? Why can't one rely on letting the ADC1 do the sequencing by itself properly?

need MULTI CHANNEL without DMA but with interrupt from timer 3 event!

Is it possible to do this with interrupts?

Hi I'm using stm32h743vit6 MCU. I selected ADC CH 3 and CH 7 but there is only disable option in scan conversion mode. Kindly guide me how to use ADC multi channel in stm32h743vit6 MCU

use LM35 ?

What should I do if i have 1 ADC but I need to sample 1 channel at very high speed using DMA and i only need to poll the other channels at fixed intervals I'm stuck

Good morning.

ABİMMM ÖZ ABİMM...

Hello hi I am working on adc multiple channels and what if am using freertos and let's say I have 2 tasks in task 1 I hav 2 channels set that is ch1 ,ch2 and in task 2 ch3,ch4 so for this can I configure each time one channel and get the value ?? Here task switching happens so can I set each time a different channel with out sequence like ch3 then ch4 and then ch2 and ch1.

Hey can i change the wait time from millisecond to microsecond in HAL_ADC_P....

hey actually i am facing the issue the my function of channel is not running initially adc_channel3(); // like this is the function which you made to run the different channel HAL_ADC_Start(&hadc); HAL_ADC_PollForConversion(&hadc ,1); adc_result_DMA[0] = HAL_ADC_GetValue(&hadc); // rawvoltage = (float)read_value*3.3/4096; // current = (rawvoltage-2.5)/0.1; HAL_ADC_Stop(&hadc); delay_us(1);

I love you
