Resolved! STM32L1 SPI DMA Receive half duplex (no HAL, only LL)
Hi All, My environment: STM32L151CB, SPI2 Master, DMA1 Chan4(RX) and Chan5(TX)I moved from HAL to LL (to save memory) and faced with the following issue:When I configure SPI to receive data by DMA and setup only RX DMA channel SPI transaction doesn't...
Write several files "simultaneously" on SD card with freeRTOS fails.
Hello,I built a test app that writes data in files on SD cards in a freeRTOS enviromnent in order to testCube (and cubeMx) librairies 'integration.I wrote a task that write data on one file, then another and so on, the file prefix is the (data) of th...
Feasibility of design concept using extern adc + stm32 gpio + dma
Hi,I am working on custom design using stm32h743zi with ad9269 16bit 20MSPS ADC. Since I am a newbie for this kind of design and I needed to consider all the analog & digital part at the early stage of design, I just simply connected the adc outputs...
Connect STM32L4xx with S2868A1
Hi, everyone.I want to connect a STM32L475RG board with an extended board, more exactlyS2868A1, which comunicated on SPI protocol. More that, i want to connect these 2 components with another Stm32L4 and S2868a1, and comunicate with them via S2-LP mo...
STM32H7 Ultra slow RAM access time of 500kHz
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...

3-Wire and 4-Wire SPI interface
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...

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...
