The SDRAM HAL module has DMA functions but there is no tab in CubeMX to set up a mem2mem DMA channel. This is with CubemX 4.27.0. Is the DMA a pre-requisite for LTDC operation or does it use it's own internal memory access.
Posted on August 11, 2017 at 05:02Hello, I am using an Olimex-E407 board to measure some signals (AC signals). After some reading on ADCs I learned that there are a few error that have to be taken into consideration when doing measurements and some ...
Hi,I've been playing around and refactoring a small test app for the STM32F769 DISCO board. The app runs fine and I retest after even the smallest code tweak.What I'm seeing is that physical position of the function SysTick_Handler within the source ...
I've been trying to adapt an example piece of code that utilizes a UART from the Visual GDB website. The adaptations are:Using an STM32F769 Discovery board.Communicate with an ESP8266 device plugged into the board's WiFi socket.I managed to work out ...

Hello,I am a student of electrical engineering and I'm now starting a project where I need to use the stm32 architecture.The idea is to use a NUCLEO-H743ZI board and to connect 8bits of the GPIO to a VGA Cable and display a 640x480 60Hz 256 colors i...
Hello,I have been working with the STM32H7 and I have been implementing the Protected Area for saving memory in the sector 1 (128KB) shared with my boot loader and the application.I have experienced two different issues with this H7 processor:When I ...
stm32l452, uart. CR1_TE is = 1, now I set CR1_TXEIE = 1. Is ISR-TXE = 1 (and INT generated) now too? Or really only if 'data is transferred to the shift register' ?
I think I've caused some problem in the way I'm coding this interrupt. For a second I thought it was a pipeline re-entry problem like Clive-Two-Zero described in a different thread, but adding a volatile variable and incrementing it, didn't seem to w...
Hello Everyone, So, I am trying to configure the SPI1 to work with DMA so I can fill in a buffer from my sensor for every occurring interrupt, so when the buffer is full and I can send it to my client server. I used CubeMX to configure SPI1 and DMA2 ...
