STM32 MCUs Products

Is it normal if MCU of NUCLEOH743 gets hot at 400/480Mhz and ~120mA current at IDD Jumper?

I am using latest CubeMx and CubeH7 versionsWith the increase in clock the MCU start getting hot especially at 400 or 480Mhz. So Is it a normal?I have also checked the current consumption at IDD jumper and it is ~120mA. Iis this normal value when no ...

How to test STM32F469AI of packaging type WLCSP168 if its receiving power?

Hi everyone,I have the STEVAL-IDP005V1 sensor board on which STM32F469AI MCU is present. I suspect that something is wrong with the D9 pin of MCU which is supposed to receive 3.3V from the power management unit on the board which I tested to be up an...

STM32F042 CAN POLLING WORKS - INTERRUPTS NOT HAPPENING

I have coded it both ways, so the hardware and software works except when switching to interrupt-driven receive. No interrupts happen, though I have checked and rechecked. The global NVIC can interrupt setting is there, and the enable. The CAN priori...

ADC single vs continuous mode. If the ADC is set in single conversion mode will a repetitive pin read initiate another conversion at each read or will the same data be read each time after the first read?

CAN Bit Stuff Error during CAN2 pins initialization

Hi,I am using STM32F103RFT6 64 pin package mcu. i am seeing can bit stuff error during CAN2 TX pin ( PB9) initialization. when mcu is in reset state this pin is in high state, the moment CANTX pin gets configure to Alternate function pushpul, Low s...

SDIO multiple block write

Hello,I'm working with SDIO to write data to a sd card and I'm using DMA. The basic process of my project is :1.Get 512 bytes data from an external ADC 2.Write it into a SD card3.RepeatI want to use the multiple block write mode, but everytime just s...

STM32F051 touch library bug

Hi,I Have two problem.first : using STM32F051R8Txcant use IO_TOUCHKEY2 at all !, have to assign IO2 to unused PIN and define new IO_TOUCHKEY.(if you need 3 touch you have to set 4 touch in CUBEMX case IO_TOUCHKEY2 doest respond!)second: why STM32F051...

Problems with SPI on STM32F429

I've got NUCLEO-F429ZI board and I'm trying to write simple communication via SPI. I've generated code from CubeMX for SPI1, compiled it under Atollic TrueStudio and run. Unfortunately I cannot get SPI working. I mean I have no clock signal on SCK P...

Hello I am trying to establish single-byte receive on stm32f091 controller by polling mode but unable to do it . Do i need to monitor any flag or clear any of the flag. Please suggest some solution.
