I am trying to get my STM32F446RE (using STM32CubeIde) into USB DFU mode via firmware rather than using the RST and BOOT0 inputs which are going to switches on the board. I know this is doable but for some reason it is not working for mewhenever I go...
Hi,I'm using an STM32C051K6T6 to read an audio file from FLASH (a book on tape, basically) and output the data over I2S to a codec/amplifier. I would like to understand the drawbacks, if any, of using the internally generated PLLI2SCLK instead of an ...
Hi ST-Members,I need to interface a 10.3-inch LVDS display with a resolution of 1920x720 to an STM32F769-disc0. I also have an H743 Nucleo board. Could you please advise on the method I should use to make the display work? Additionally, I plan to ini...
I am trying to drive a lc resonator from a h bridge. Frequency of the resonator changes when inductor is loaded. TIM15 creates the complimentary PWM for the H bridge. I need TIM2 to read the new frequency of the resonator so i can adjust the PWM freq...
SPI communication using DMA on the STM32H743.We have created a program for SPI communication using DMA, The first send/receive with HAL_SPI_TransmitReceive_DMA is successful.However, when the exact same process is executed afterwards, all received va...
Hello,I have a H7 design with multiple UART/USART used to communicate via RS485 drivers (XR3072).I have programmed kind of loopback test by connecting the A/B signals of two RS485 busses.For this I use 2 DMA channels for each UART, one for RX and one...
I am using an STM32G4 microcontroller with UCPD and the USBPD middleware. I was following this tutorial (same as AN5418 https://www.st.com/resource/en/application_note/dm00663511-how-to-build-a-simple-usbpd-sink-application-with-stm32cubemx-stmicroel...
I’m working with an STM32-based system where the RTC is running on the internal LSI. My goal is to maintain reasonable time accuracy (within a few seconds) while periodically receiving the correct world time over an external communication interface.T...
Hello dear community,I’m a beginner with STM32 and I’m trying to interface an APS6404L PSRAM to my STM32H7S3L8H6H using the XSPI1 peripheral. Despite configuring XSPI in CubeMX and generating the initialization code, I see no activity on any of the X...
Hi,Our company need to make a I3C demo, so i'm studing I3C protocol with NUCLEO-H503RB and a generic IIC device.We know, I3C bus is compatible with IIC device. I meet a problem.when I2C master read 4 byte data from IIC device’ reg 0x10, IIC master p...
