STM32H743 ADC sample x steps and each step sample y points,but the datas of first step are diffeternt from other steps

The ADC is trigggered by TIM,the sampling rate is 2M and TIM period is also 2M.I want to sample X steps, and each step samples Y points so that I could get wave figure with these data. However,I found the question that described as my question title...

Question about looping a DMA transfer to the internal DAC

I have a question with regards to DMA. When I do transfer, do I have to re-transfer once I finished transferring my data to the DAC? I am trying to just have go through the same points over and over again, so it could be a time saver if i could do th...

Why is my CubeMx created USART not running?

Hi Guys,I created a Keil5 project with CubeMX. In this project, i only created a USART (USART1) periphery application. So simple as that. BUT: My usart seams not to run. I enabled it by "HAL_USART_ENABLE_IT" in the setup and call the "HAL_USART_RECEI...

Can TIM one pulse mode support two channels?

Hi, I try to use STM32 timer with one pulse mode and two output compare channels. I use cubeMX initialize the code, but now I have question abut how to enable two channels OC?HAL library provide function HAL_TIM_OnePulse_Start(), which only have one...

Why examples, with final credentials, STM32CubeExpansion_SFOX_V1.1.0\Projects\B-L072Z-LRWAN1 does not work?

My problem:I bought the new demo board but it doesn’t work with sigfox credentials.STM32CubeExpansion_SFOX_V1.1.0\Projects\B-L072Z-LRWAN1I am using IAR system environment.I see the same problem using both ATcommands and pushButton examples.  // origi...

Capturing an Image from Camera Interface, saving it to Internal Memory and displaying it with a user defined button from Stemwin

Hello All,I am currently using STM32F746G-DISCO board for prototyping my smart home system application. I am using Stemwin for graphics. My application runs the camera on continuous mode on a rectangular window on top of a graphic window which has bu...

Hello, Can anybody tell me how to generate sine waveform using STM32F334R8T6 MCU? It has 3 channels (12 bits) DAC.

I am using STM32CubeMX to generate source code and Keil 5 for compiling the code.Please help.Thanks & Regards.Sagar.

Simple "Hello World" LED blinking example without HAL available?

Hello, guys! I have problem with STM32L0 ADC. I measure VrefInt voltage but the behaviour of the ADC is not stable - it reports corect values(4095) alongside with incorrect values (1950)?! Would you please help me.
