Hey all,I’m trying to squeeze the lowest possible STOP1 current out of an STM32U031F8P6 (TSSOP-20), no external crystals. The board itself looks fine: in the deepest mode (Shutdown/Standby) I see < 0.5 µA, so I don’t think it’s a hardware leak.Goal (...
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...
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...
Hi @Amel NASRI ,Does STM32H755xI support OTP (One Time Programmable) memory in it's flash like STM32BH7B3x?Muthukrishnan
Hi, On the STM32F303, the TIM1 timer is running in input capture, slave mode – reset, with the trigger source set to TI1FP1 (CH1 direct rising, CH2 indirect falling) to record the incoming stream. It operates with DMA in circular mode using two buffe...
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'm using STM32G0B1RCT6 use cubemx generate cdc project works okbut when I edit endpoint to 0x03 it Not working properly USB packet capture endpoint 0x03 returns stall ny Idea about this issue and how to fix it please?Thanks.
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 ...
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...
Hello,I want to use the TW9992 NTSC/PAL Video Decoder for STM32N6 to transfer an NTSC camera (720x480 resolution) to the MCU via MIPI-CSI and display it on the screen. I have attached the code below.static void MX_DCMIPP_Init(void) { /* USER CODE...
