Hello,So in an earlier question, I asked about how I can suspend/restart multimode ADCs of the STM32F429 configured in the triple interleaved mode.To find an answer, I set up a blank project in which I periodically start/stopped the ADCs after differ...

Hello,I have a button with a pause icon on it in TouchGFX, and I want to know how I can change the pause icon into a play icon after it is pressed. TouchGFX only gives me an option to change the icon while the icon is being pressed.

Hello,This is a follow-up to my earlier question, to make a 7.2Msps digital oscilloscope using the STM32F429 Discovery board. In the last post, I was able to capture a buffer from the triple interleaved ADCs of the MCU and display the captured wavefo...

Hello,I'm planning to use the STM32F429 with its triple interleaved ADCs to make a 7.2Msps digital oscilloscope.So the thing about digital oscilloscopes is that they also record samples before the trigger events.To do so, they have a circular buffer ...

Hi, I've configured the triple ADCs in Interleaved mode with DMA writing the ADC data in circular mode 2 on my Stm32f429 Discovery board. What I'm trying to implement is:Initialize DMA and ADCsWait for an external interruptPause the DMA transferShow ...

I do not quite remember the issue at this moment, But at the time I was working on this project:https://github.com/mmahdim/stm32f4scopeIt is now working and only needs a bit of code cleanup.

Sorry if I keep posting beginner-level posts  But I think I just found a solution for what I'm trying to do.I realized that the TouchGFX is not only relying on the FreeRTOS to execute, but also LTDC interrupts (in the osWrappers). So instead of susp...

Thank you for your answer,There's one thing that I don't understand here.Here I have created two tasks:The first one is the TouchGFX task, with Normal priorityAnd the second one is a task that runs every 500ms and starts/stops ADCs (ADCmanager), with...

Just a quick update,I disabled the TouchGFX task, and made a new task with the same code that I was using for testing the ADCs, and realized that when the TouchGFX is disabled, the ADC doesn't stop.So the problem begins when the TouchGFX task execute...

Interestingly enough, the FIFO does not help by any means. No matter what combination of burst size and threshold I choose, each time the suspension occurs at precisely the same time (7.04ms).Increasing the DMA transfer size (NDTR) also does not have...
