Finally, someone who explains what they're doing. Thank you!

The best explanation of the normal and the circular modes of DMA.

after all day long trying to understand DMA finally i get it . Thank you. keep up the good work

Great help. You deliver the information in a easy to understand way. Thank you. I would love to see some more ADC stuff like multichannel DMA.

Keep on doing videos please. Great they are

Thanks!!! Great video!

Can you make one for simultaneous ADC reads with DMA?

It works well. another tutorial just didn't. thank you.

Hello Thanks for your easy and fast Learning. Please continue more by Dual ADC with DMA and also injected simultaneous + interleaved mode Best regards Ali

Hi.,., How to share the ADC data via uart so that i can see in some com port. Please help i am trying to sample and store an audio signal. Kanagachidambaresan G R

Good video, thanks...

Hello. First of all great video. Helped me a lot. Second, I would want to know hot to read de DMA buffer and store it into a variable. Could you help me?

Any thoughts or plans on an example using a TIMER to trigger an ADC scan with DMA ? For example, I've set TIMER4 CH4 to Update Event (Output Compare), and then set the ADC's External Trigger Conversion to : "Timer 4 Trigger Out Event". The ADC's DMA setting is set for Circular. In theory, HAL_ADC_Start_DMA and HAL_TIM_OC_Start , should cause new samples to be DMA'd into memory at the TIMER rate. However this doesn't seem to work.. in the clock configuration, there is an APB1 Timer Clock, APB2 Timer Clock, and ADC Clock.. I assume the APB clock connected to the desired Timer should be used for the timer prescaler settings.. but what should the ADC clock speed be? Also, if the Timer triggers the starts of a SCAN conversion, does that mean the first channel of the scan won't be sampled at the same time as the last channel? Even though all scan channels are being sampled at the rate set by the timer event? There's also another ADC option that might be the problem: "Conversion Data Management : DMA One shot, or DMA Circular" Since I've set the ADC dma settings to circular, not sure what this particular option is adding.

Great video thank you so much! In this video, you employ 1 ADC with DMA. it is possible to use DMA with 3 ADC simultaneously?

Great video thank you so much! I've been trying to make a guitar pedal, which requires the ADC to copy its value to the DAC. Could you make a video on what setting should one use to do so?

Nice Video Carry On.

thx from China

Hi, great channel! Here you have a new subscriber. I would like to know how to implement DMA to I2C?. I want to read acceleration from KX132 accelerometer but works only once time, only enter to transfer complete interrupt once time and it never enter again :(. Do you know something about this? I have a post in stackoverflow about this issue if you need more details. Thank you !!

What is diference with one ADC and multiple channels ?

what was that noise at 1:55 ?

Well, I did exactly the same and ended up not having that DAC_Channel_1. Fuckn bullshit.... Mine asks for variables that I've defined, and does not give me the option to pick DAC_Channel_1.... or any other channel.

Minute 5:40 ::: you are passing the 'value_adc' wrong to the HAL_ADC_Start_DMA function. It should be (uint32_t*)value_adc or (uint32_t*)&value_adc[0]
