I am using NUCLEO-F756ZG board. Previously, I tried using ADC with timer trigger and it worked perfectly. Now, I tried to log the timer's pulse with another timer's input capture. It works but the captured timestamps seemed unusually slow. So, I disa...

Hello,I am using NUCLEO-F756ZG. My application is ADC related. I am measuring an analog signal at high sampling rate. Recently, I had a discussion with my team and had an interesting proposal. Our target signal is pretty much guranteed to be within 0...

Hello. I am new to using STM32 MCUs and this forum has helped me a lot in getting familiar fast. I am using using NUCLEO-F756ZG board. I have tried ADC with DMA and timer trigger and it all works fine. Now, I am trying to switch timer period dynamica...

Hello.I am very new in using STM32. I am using STM32H747I-DISCO board. For my project, I only need one ADC in differential mode. Previously, I tried to use DMA with ADC but it never worked, even the "ADC dual mode interleaved" example provided by st ...

I recently bought a brand new STM32H747I-DISCO board from mouser. Read up user manual and tried to use it for the first time. When I connect it to PC with USB cable, LD10 lights up red. Then LD8 lights up green and LD10 starts blinking red. STM32Cube...

Hello Sarra.S,Thank you for replying. I checked the thread you linked and I had considered the possibility. But in my case, the problem seems different. And the issue seems to be related ADC triggering rather than sampling time or timer output. I don...

@TDK, Thanks for clearing that up. From what I gathered from scouring internet it seems that most SRA ADC measures from 0 to VREF+, custom VREF- seems rare. Furthermore, these ADCs doesn't seem to work with very small swings like 50mV. What I wanted ...

Actually, setting the DMA to circular mode worked. Just moved the adc disable and dma disable calls to the interrupt callback. So, the code is like this now,void Restart_DMA(uint32_t ARR_val, uint32_t* new_address, uint32_t new_len) { //Clear DMA fl...

@Bob SThanks a lot. That is something I did not consider.@TDKI think I've figured out the problem. It was the overrun behavior. CubeMX defaults it to preserved and I didn't change it. Then in debug mode, saw that the first few conversions happen in 2...

ADC triggered by timer running at half of expected speed

External VREF+ and VREF- for ADC

What is a good way to restarting ADC-DMA with different buffer?

Confusion about ADC sampling speed and sampled value
