I have come across a rather weird problem and would like to get some direction.I am using STM32F756 nucleo board. I set ADC1 to trigger by TIM1 (the complete project uses some other peripherals). TIM1 is set as PWM generation. All these are set using...

I am using NUCLEO-F756ZG. I intend to use two of the ADCs but in different conditions. ADC1 is configured for DMA and triggered by TIM1 to run at high speed (1 Msps), ADC2 is configured for interrupt mode and triggered by TIM8 to run at low speed (1~...

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...

If the receiving side is setting a 20ms delay for next reception, that might be the cause. Since the reception routine takes some time to process.

In my project, I need to sample some analog signal at different sampling rate and store the data in different memory location. The signal is in one channel only. So, I need to get one set of data; tweak timer frequency, change DMA buffer location and...

I have been disabling the DMA after calling HAL method. This is what has been setting the interrupt. This I just tested. So, it is not a bug, I just didn't know this information. Found it from the below discussion-https://community.st.com/t5/stm32-mc...

I think I have figured out what happened. Apparently, disabling DMA sets the TCIF flag and fires the interrupt. I did not know about it. Now, the problem is that in my project, I need to disable DMA to change the buffer pointer and data size and this...
