Check FlashErased or Readout InternalFlash ECC on STM32H7

I'm working on the STM32H7 series, and in my scenario the data to be written might be the erased-state byte (0xFF) all over the flashword. In this case I'm unsure whether or not the ECC may change.What is the idiomatic way of checking if the bytes ha...

Hello, I am using stm32f103 in my project. Software as GPIO_PinRemapConfig (GPIO_Remap_SWJ_JTAGDisable, ENABLE); I disabled it with the command. But now I can activate it back, I don't know how.

HelloI'm following the instruction of https://www.st.com/resource/en/data_brief/stpm4raspi.pdf to setup the tpm driver on my embedded linux using ST33TPHF2ESPI tpm module. But unable get /dev/tpm0 and /dev/tpmrm0 present due to driver read spi failed...

Implement PWM dithering 1 bit

Hi I am working on stm32f070. The STM32F0 system clock = 48MHz,I need to set the PWM frequency on 23437Hz.Therefore, PWM resolution = 48MHz / 23437Hz = 2048 (11bit)​How to use PWM dithering technique to reach 12-bit resolution on PWM frequency 23.4KH...

Hello everyone,I have designed a board with STM32F750N8, 22 Bit Parallel Nor Flash, 13 Bit SDRAM, QSPI Nor Flash.Now i am trying to read, write data, read device id from fmc nor flash (other memories not enabled). But when i try to read device id, ge...

want to zip and unzip assets in stm32f4 MCU

Hi All,I am using STM32F429ZIT6 MCU. And we were planning to zip the assets and unzip them inside MCU. Please can anyone suggest the best starting point for good libraries which can do this.Thanks,krishna

ADC Error to HIGH.

Hey Everyone;I`m working with the STM32L031K6T6 in a project that I require 2 ADC channels. The ADC look to be working with a huge measurement error:Project description:Signal Type: Sinusoidal ( 1Vpp) with offset of 1.492 ( Offset provide by independ...

STM32L496VGT6 - Does anyone know for a fact that receive works on USART3? Please no "assumptions" -- I already did that.

Transmit works to PC via FTDI cable.Receive works from PC to PC (TXRX looped) So FTDI transmit working.Receive generates no interrupt.Receive sets no status.Receive data register remains zero.As GPIO, receive pin sees signal.It is as if the alternat...
