HeyI work with the eval-board Nucleo h743ZI. I implemented sine wave playback using the DAC and DMA, and everything worked very well.After that, I designed my own board with the same microcontroller and added an external 25 MHz crystal.I couldn’t get...
Hello,I am using STM32H750VBT6 to perform microSD card write operations. After a number of writes, the CPU sometimes resets during a write operation. At the same time, the Vcore (1.13V) rail shows a voltage drop. The issue is random, but the higher t...
I am developping STM32F469 with TouchGFX to display with LTDC in RGB888. I can display an image in the internal SRAM. However, when trying with SDRAM, the screen truns black, and the debugger can only read 0s. But when I tried with the framebuffer re...
Hey everybody,I was wondering if someone could help me correct my firmware that I've written.I created a custom board using the STM32C011F4P6 MCU. I put an FTDI UART-to-USB converter on the board to be able to view outgoing messages from the custom b...
Hello we try to use the backup sram on 0x3880 0000 .We have build the software :#define BKPSRAM_BASE 0x38800000UL #define BKPSRAM_SIZE 0x1000UL typedef enum { BkpSram_Init = 0 , BkpSram_Wait = 1 , BkpSram_WriteStr = 2 , BkpSram_ReadStr = 3 ...
We are developing a product that needs the ability to run 3 separate CAN interfaces connected to 3 separate CAN buses. I have the NUCLEO-F413ZH and I can successfully initialize and start CAN1, CAN2, and CAN3 and transmit from each of them in a sing...
Hello STM Community,I am developing a custom board based on the MB997E reference design. In this design, the EMIF02-USB03F2 (USB ESD/EMI protection device) is used, but since this part is now obsolete, I am migrating to the USBDF01W5.I have updated ...
Hello, I am using the STM32F407VGT6 microcontroller for a project involving GPIO interrupts, but the interrupt is not triggering reliably. Despite configuring the interrupt settings, it occasionally works, but other times it misses the edge completel...
Hi,I'm working on a design containing a STM32U535. I need to connect it to a SDHC interface (µSDHC connector). The STM32U5 documentation talks about a SDMMC1_CKIN signal. It is not clear to me if this signal is always required or not. I think the doc...
I use keilMDK V5.42.0 and follow apnt-333 to make a FLM file, and successfully got a FLM, when I use in my app Project,my internal flash works well but external flash got an error shows ---------------------------CMSIS-DAP - Cortex-M Error--------...
