Hi,I am using STM32H747. I have successfully write&read micro sd card over SDMMC2 peripheral while debugging. But after debugging, when I power cycle or reset the board, I am not able to use sd card. I see FatFS open file failing. The board is arduin...
I have the M7 core running and printing debug messages to the IAR Workbench terminal, and also have the M4 doing something similar. My probem is that I get a hard fault in the M4 core if the its printtf messages are included in the build. If I don...
I am trying a PWM output with jumper connectors.when mains fail(input supply)PWM is on indicated by a lamp and OFF when there is a supply .in between if the supply is OFF and Lamp is in ON there is a jumper connect to PA6 (input)of stm32c011f6p6.if t...
Hello. I am currently working with the STM32L031 Nucleo board:https://www.st.com/resource/en/user_manual/um1956-stm32-nucleo32-boards-mb1180-stmicroelectronics.pdf The board has integrated ST-LINK so it is quite easy and convenient to flash the devic...
Hi,I am using B-L475E-IOT01A. I am wondering that MSI can be changed on the fly when it used as system clock source.In `HAL_RCC_OscConfig` from STM32L4Cube drivers code, it looks like ok. But I didn't find any relative information from l47xxx manual....
firstly i am new to here, dont know much rules about posting. 1 minute ago i saw post about shorted power dont kills mcu but can it damage stm32?so i shorted my 3d printer board(stm32g0b1ret6 probably) via 3.3v and gnd(general probably). i checked by...
Hello all, I have designed a board for sensing purposes and I am using the following ST components: STM32U575ZIT6Q. I am supplying this component with 3V3, which I get form a 5V/3V3 LDO. Between the output of the LDO and the supplying rail to the STM...
I have a test project that sets up TIM3.3 to count microseconds between falling edges of the timer input. The timer is started with a call to HAL_TIM_IC_Start_IT(&htim3, TIM_CHANNEL_3); to start timing the input. Inside HAL_TIM_IC_CaptureCallback(*...
Hello everyone,I'm working on a project with a STM32L072CBT6.I'm using LPUART (PB10 / PB11) at 9600 bauds to communicate with an other board. For low power consumption, i'm using LSE for my LPUART.When i check my bauds rate on my oscilloscope, i get ...
Hello,Is there any specific guidance regarding how to improve wakeup time from the various STOP modes? The U5 Reference Manual mentions that configuring STOPWUCK = 0 will use the MSIS up to 24 MHz, which would be faster than HSI16. I've used that alr...
