How to get temperature (degC) from the STM32G491x internal temperature sensor?I have my ADC working and producing raw count values. Eg: 303.So assuming a working voltage of 3V3 and maximum count value of 4095 then I assume that I must multiply the ra...
I am unable to make working ThreadX USBX Host example for STM32U5 adopted for Nucleo-U575ZI-Q.All, but the last setup step described in Introduction to USBX section 3.3 complete properly, but when finally HAL_HCD_Start() is called, ThreadX crashes. W...
Hi! I have working on the watch Dog implementation in STM32F446RET6.The board which I have used is NUCLEO-F446RET6.I have followed the below mentioned steps, 1. Enabled the IWDG in system core using CubeMX of STM32CubeIDE. (which takes the LS...
Hey all,I’ve recently encountered an issue with setting up the CAN module on my STM32F4 and hope that someone is able to help me:After buying the SN65HVD230 CAN Board, I tried to set up the MCU so it can communicate with the CAN Bus. For that I solde...
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...
