Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Dear ST's experts,I want to send/receive data through UART between STM32 and PC. The data must be sent to PC every 500ms and then STM32 receive data from PC. I have configured UART2 with DMA in circular mode. I am using the function HAL_UART_TxCpltCa...
Hello,I am working with the STM32U5G9ZJT6Q MCU to implement a USB UVC application. Here are the key details of my setup:MCU: STM32U5G9ZJT6QSystem Clock: 160 MHzUSB PHY External Clock: 32 MHzData Source: DCMI captures data at 640x480 resolution in 8-b...
I'm looking for some guidance on using DMA with SPI. I have the M4 core on an STM32H755 set up as a master in full duplex mode, and as long as I invoke the SPI transfer using interrupts, the program runs fine. When I try to migrate to DMA, however, I...
Hi,I'm working on a STM32h747 dual core and I'm trying to put the CM4 to sleep so that it wakes up only on a CM7 event.I used _WFE on CM4 and _SEV on CM7 but the CM4 is never wake up. I release a HSEM directly after WFE in CM4 to notify the CM7 that ...
Hii Team, I'm using STM32G070RBT6 MCU to communicate with ADS124S06. I've configured the SPI on the MCU for Mode1 and GPIOs CS, RST, START pins as output (NO pull up/ pull down) and DRDY as input (NO pull up/ pull down). GPIO Configuration:SPI Config...
Hello everyone,I'm using AZURERTOS on my STM32F407 microcontroller. My goal is to use the FPU to perform some mathematical operations (FFT, etc.). Could you help me figure out how to activate the FPU and how to tell when it's active, taking into acco...
STM32H523HEYX Flash Write Issue1.I’m currently working on a project using the STM32H523HEYX.I'm using STM32CubeIDE, and the firmware libraries are up to date.I’m also using STM32 X-CUBE-FREERTOS.I’m trying to write data to Flash memory using the foll...
Hi everyone,I’m setting up LVGL on a custom PCB using an STM32H747BIT MCU. The display is connected via LVDS, and I’m using DMA2D for transferring the framebuffer to the screen.The issue I’m facing is that the DMA2D transfer complete callback is neve...
Hello.I've been struggling for several weeks to fix an issue when sending data over MQTT using LwIP on an STM32F407 microcontroller.For periodic message publishing, I'm using the following code:void MqttPublishTask(void const * argument) { err_t err...
