Hi everyone.I tried adding USB_OTG_FS/Virtual Port Comm to STM32F407VET6 as a device only, but the problem is that when I try to connect the STM32 USB to my PC/laptop, it says “USB not recognized” on my PC/laptop, and I think it might be a problem wi...
Hello, everyone.So, I want to assign a serial number/device number to all my devices, and each device has a different serial number/device number. My question is, how can I change the serial number/device number with the same firmware without having ...
Hey all,I have been debugging a nasty issue that I have been having over the last couple of days. I am using the STM32n657I0 MCU. The issue that I observed were random crashes in my code. Luckily the problem was well reproducible. What I observed was...
Hi everyone,I’m working on an audio recording project using the STM32H747-DISCO board with its built-in PDM microphone. The recording works — I can clearly hear my voice — but there’s a constant background white noise in the recording. I’m trying to ...
Hello, I am reading 6.3.30 LCD-TFT controller (LTDC) section to interface with DS90C385A (LCD) or ADV7125 (VGA) Assume that LCD Clock (pixel clock) polarity is set to high. Ideally, we can expect rising edge of clock aligned to the middle of the data...
I am currently working with the STM32U5G9J-DK1 development kit interfacing with a Tianma-based display. I have successfully managed to update the display using adaptive command mode with DSI long and short write commands. However, I am encountering i...
Hello All,I'm trying to keep my MSC + CDC USBX connection alive on my STM32U575. When I connect the device via USB cable, Windows Explorer opens and displays the files on the W25Q NOR Flash. I can select a file and open it from the flash. I can al...
Hey all,I would like to confirm some current consumption figures present within the STM32N6570 datasheet.I am particularly curious about the current consumption numbers in the various sleep modes.Table 31 (Current consumption in Run mode) suggests ID...
Hello community,I am running in an issue with the VREFINT calibration value of the ADC.For calculation I use the __LL_ADC_CALC_VREFANALOG_VOLTAGE function from the stm32u0xx_ll_adc.h file and I'm getting wrong values.The Chip is powered with 3.3V and...
Hi, I'm trying to get a PWM output that changes duty cycle on each period with DMA in circular mode. I have seen other similar posts (ultimately I'd like to control a WS28 LED with 800kHz), but they are for other MCUs and everything is different in t...
