Hi AllI have been experimenting with setting flash sector write protection but found that when I did I could no longer program with the debugger. I managed to reset the options by writing the unlock sequence via the debugger (that can still connect) ...
Dear all,I'm using the STEVAL-PCC009V2 based on a STM32F103RBT6 microcontroller, set to work with an internal clock frequency equal to 72 MHz so CK_INT = 72 MHz (refer to figure 100 of RM0008 Rev. 19, pag. 367/1132).I need to obtain a 10 ms time base...
I have basic understanding about buses, but this term is new to me.What's bus turnaround phase - and measured from where to where?Google hasn't been my friend on this.
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...
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...
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...
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...
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...
