Hello everyone,I'm current creating my first STM32 design using STM32F411 and have a need for the USB function on the MCU. The datasheet states that it requires a 48 MHz clock generated by a PLL connected to the HSE oscillator.And I've currently chos...
Dear,Recently, when working with STM32U575 and using WWDG, I've encountered an unclear behavior when I set the controller to STOP mode by using HSE or HSI clock source.By using HSI and LSE clock source (See below code), when enter STOP mode, WWDG is ...
Hi there I'm working on a project where I need to create 4 different pulse trains on 4 different GPIO pinsI've created and formatted a uint32_t array to be able to directly write to the GPIO BSRR registerI want to use DMA memory to peripheral in circ...
Hi everyone,I'm working with an STWINBX1 board and using ST-LINK V3MINI for debugging and serial communication. However, I can't see any output on PuTTY (COM3 @ 115200 baud), even though everything seems correctly configured.Setup Details:Board: STWI...
Hi all,I'm designing a product that will have a USB boot-loader.I would like to choose a micro-controller that supports secure-boot as well as an ability to completely lock down the micro-controller such that no flash can be read from it. I understan...
Hi am relatively new to stm32 development.I would like to understand the difference between HAL_GPIO_EXTI_CLEAR_IT and HAL_GPIO_EXTI_CLEAR_FLAG Thank you!
Hello,I'm desperate. Just want to concvert some data with the ADC3 with DMA on a H755.No chance! DMA doesn't work, and even a cyclic sample only produces the right values for the first turn. After that, only max. resolution is returned. 12 bit => 0x8...
I am using a STM32F103 and having issues to make an USB application.I generated the project using CubeMX and I am not being able to transmitt a message.Here is the configuration:Main is like this (It is C++ in case it matters): int main(void) { H...
Board: STM32F407G-DISC1IDE : StmCubeIDEHello, I am trying to drive ADXL345 accelerometer sensor via SPI. I succeed in receiving the device address (0xE5).However, afterwards, when I tried to read two registers' value consecutively. I always read...
Dear ST Community Member, I hope you are all doing well. We are currently acquiring audio using the STM32G4 and 2 PDM microphones in stereo mode. I would like to know how to split the left and right channel data. Could you please provide me with the ...
