STM32L476G Discovery Board VBUS Voltage on PC11
Hello,I have an question concerning the VBUS Pin which is connected to the STM32L476G Discovery (PIN PC11) directly. Why isn't 5V an problem for the PC11 pin? I thougt 5V would cause overvoltage?

STM32L4+ issues when using UART with interrupts
Dear community,I am using the Nucleo-L4R5ZI board with STM32L4R5ZI chip embedded to experiment UART.Unfortunately, I am facing an issue when using interrupts.I looked up through the BSP (STM32Cube_FW_L4_V1.15.1) provided by ST if examples were using ...
STM32L412 USART transmit using DMA drops characters, must use HALFWORD alignment
I set up DMA for a USART transmit operation with an ST32L412. Settings are 115200 baud, 8 data bits, no parity. I thought everything was working until I noticed the third character in all my outbound data not showing up. It turns out the default BY...
STM32F030 debug problem
Hi,i designed myself a PCB with a STM32F030 with breakout pin (SWDIO, SWCLK, NRST, GND, UART1_TX, UART1_RX). When I try to debug it with VS Code, it doesn't work. I tried it with stutil, openocd (on st-link v2) as well as bmp (on BMP Bumpy). Nothing ...
Resolved! UART DMA sends sometimes random data when using ADC
Hi everyone,I'm relatively new to STM, i'm making my diploma thesis with it. It's going to be a mini, portable oscilloscope, but at this point I'm totally stuck. I started using ADC with DMA, but soon I realised this might be not the perfect option, ...
How does the disabling of VREFINT influences BOR?
we have a STM32L07CBT6 and we want to disable the VREFINT with following HAL functionsHAL_PWREx_EnableUltraLowPower()HAL_PWREx_EnableFastWakeUp()but still want to use the BOR. Therefore I checked the section of VREFINT (6.2.4) and BOR (6.2.2) in the ...
Resolved! How to get PWM from lidar sensor?
Hi everyone, i'm quite new with the stm. Currently im using the stm32f411 discoveryboard and trying to get the pulse width in order to measure range, i did try to search for solution and find out about input capture method but the code is on sw4stm32...
reason H745 not booting
Hi,I have a custom board with an STM32H745 which doesn't boot / I can't connect to.I've noticed that three of the gnd pins are not connected K15, L15, M15, would this cause the problem?The design is using an external 1.2V supply which is fine. 3.3V i...
Simultaneous use of two FDCANs of STM32H743
I am developing a device that simultaneously logs two CAN lines using the STM32H743.I saw "Wrong data may be read from Message RAM by the CPU when using two FDCANs" in STM32H743 Errata document.I need a detailed explanation of the above Errata.I am t...
