External clock for STWIN data adquisition

Hello friends of STM. I am new to STM32 MCUs, and I am working on a project using the STWIN. I have another Data Adquisition Card that is programmed to output a clock signal when I send a command or press a button. I would like to datalog the signals...

Hi, I cannot seem to be able to join the meeting, any advice?

About Tamper Protection.

Hi all,I'm reading about Tamper Protection on STM32 MCUs.Is this to protect, for example, a device from someone triyng to open the external case?Can you detail some more applications of this feature?

Clock configuration when executing program from boot.

I have a question about clock config.Is this a right way to execute program from boot and set clock config like HSE and PLL, then execute program from user app and set clock config again? Actually, there is an error when executing user app.It seems ...

I am working on a project to read AC power. To do this accurately, I need the Voltage and Amperage to be read at the same time. I see the STM32F303 does this with simultaneous mode. which stm32 cores support ADC dual simultaneous mode?

STM32F429 USART baudrate max rate

Hi allI used STM32F429 connected with LTE module by USART3，but I can only set the baudrate 230600. If I set 460800 or 921600，MCU can't transmit or receive data from LTE.How can I set the baudrate over 230600??void uart_init() { UART3_Handler.Instanc...

Trying to setup DMA for I2C on STM32L4R

Hi,I'm trying to set up DMA transfers for I2C sensors on STM32L4R9 MCU.I've followed the documentation and analyzed the HAL implementation, but the DMA channel IRQ handler is never triggered.Here's the specific sequence of steps that I'm performing:F...

WWDG interrupt(EWI) is not getting while writing Flash

Hi ,I am in STM32L071CZ and using window WDG EWI to refresh the WDG counter to avoid RESET.window = 127Counter = 127Prescaler 8Enabling the EWI and reloading the wdg counter in the ISR to avoid the RESET by WWDG.But while writing Flash it seems the W...
