STM32 MCUs Products

Upgraded my project to a new MCU, going from 80MHz to 120MHz SysClock. Since then my USART1 and 2 do not work well. My debugging until now suggests a baud rate problem. Where (which file) can I modify the prescaler/divisor if needed?

STM32F429 bank swap for OTA update

HiFor a project I am using a STM32F429ZITx and need to implement OTA functionality. With single bank chips I have previously put the update into the free part of the flash, then copied it over and restarted.With 2 banks I came as far as erasing the u...

STM32H755ZI SPI / Proper way to receive data

Hi everyoneI'm currently working with the STM32H755ZI SPI1 peripheral. I'm using low level driver to read 2 bytes of data. I'm transmitting 2 dummy data bytes (0xFF) in order to get some response from the SPI slaves. Most of the time, the receive wor...

Hi i am using nucleo L073Rz board , how do we authenticate a user application bin file flashed in to a board from iap is the correct bin and move on to run.

The problem is crc used in iap for transferring the bin file is to only check for errors during the transfer process , however i dont want any random bin files to be flashed into the flash or executed from it, only certain signed bin files need...

Is it possible to read from multiple ADC channels on Nucleo L011K4 (or on L081KZ)

Hi! I'm pretty new to STM microcontrollers and I found myself in a strange situation:I want to create a prototype for a project on Nucleo-L011K4 (and later use L081KZ for the PCB version) and I need to run ADC on multiple sensors paralel. But all tut...

I would like to design IR thermometer non-contact. Please suggest me as MCU with 48(preferred) or 64 pins, ADC 16 bit, with Timer, SPI, I2C, UART, Program memory 16 to 128kB, Zero-Drift Amplification (optional)

__disable_irq() in ISR possible?

Hello,I have a global variable, wich is accessed by multiple ISRs. Can I safely disable and re-enable the interrupts within an ISR using __disable_irq() and __enable_irq()?Or is there a more elegant way of protecting the variable access?best regards,...
