Hi, I am new to STM32. I have a STM32H723 nuncleo board where I want to sample 8 bit data from the on-board ADC at the maximum frequency of 3.6 MHz. Then I want to directly transfer the data to a SD card using DMA with SPI. Preferably I would want to...
In the STM32L562 reference manual (RM0438), v7.0, the section 11.6.13 "GPIO register map" is missing the registers MODER and PUPDR (which are documented in the preceding sections).
Hello,I'm planning to use the STM32G474 to read a pulse width. This width is a delay value in nanoseconds.I'm wondering if there is any possibility to use the High resolution timer (HRTIM) for that operation.I would use the events to trigger a rising...
Hello everyone,I'm working on a project where i use 2 STM32 MCU which communicate with each other with LPUART and DMA.My STM32 references : STM32L072CBT6 and STM32L010C6T6I have a problem with this communication with LPUART and DMA. I see that error ...
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...
