Hello, I am working on developing board where STM32H7 will talk via SRAM interface to FPGA and i hit the problem.I use IAR ARM and H743I-EVAL SRAM example, and guess what, if i make simple loop with just single write to SRAM like this, I only get 50...

Hello,I have to use STM32F030C6 controller. it has only one SPI interface.in my project i want to connect external flash memory and TFT DISPLAY both on single SPI with controller.problem is TFT display is 3-wire SPI interface & flash memory is 4-wire...

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...
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...
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...
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...
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...
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...
