I am working through a workshop tutorial on how to configure and use GPDMA transfers via the linked list functionality provided in STM32CUBEMX. When setting the linked list runtime configuration a Source Address, Destination Address and Data size are...

Hi, I am Driving an AMOLED display (GRAM) with QSPI.In blocking mode everythings works fine, but now I trying to "update" it using GPDMA, nothing works. Any advices ?So in blocking mode I used the typical : OSPI_RegularCmdTypeDef sCommand = {0}; sC...
hi various SOCs in STM32 family e.g. stm32f407ve, and many in the F7, H7 series features a "USB 2.0 high-speed/full-speed device/host/OTG controller with dedicated DMA, on-chip full-speed PHY and ULPI"But your STULPI01 is a μTFBGA36 package. https://...
For some reason I need to rewrite I2C functions from HAL to LL. As I aim to achieve good power consumption results, I decided to use DMA and IT in order to save as much resources as I can. There is all ok with writing data (HAL1 and LL1 pictures) but...
Hello community,I configured the uart dma in my project based on the project example USART_TxRx_DMA_Init, and stuck in frame errors, one of the errors is the end of the string seems to be swapped.Sometimes there is no problem the end of the string is...
The problem is that the convert/chip-select pin needs to be asserted for about 700ns for the conversion to complete.The NSS signal of the stm32f4 only is asserted a very short time, so that would not do.Maybe use a timer to generate the convert pulse...
Posted on April 11, 2018 at 12:31Hi, I wan to use the dma to send data to MFT1 or MFT2 of BlueNRG-1. but i can't find the MFT registers to set to use dma update the MFT data.so how can I set that?Best regardsconnor.zhang#mft #dma #bluenrg-1
