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...
Good morning, I need to connect two h7a3zi-q board via uart (only one way required), but by only connecting tx1->rx2 the programs run but I get empty strings, and by also connecting the grounds of the two boards the tx program gives HardFault. I'm su...
Hi everyone, I'm encountering an issue with the STM32H747 dual-core MCU during the transition from bootloader to application. Here's a summary of the setup and observed behavior: Setup: Bootloader (CM7 core): When the BCM4 option byte is enabled, the...
Hello everyone,For a while now, I have been writing my hardware jpeg driver for the STM3U5G9, I am near the end but a last (last?) major problem remains.With a grayscale 8-bit image (on the left), the output encoded image (on the right) is totally di...
Hi,I'm going to use four different OpAmps in the STM32G474, namely OPAMP3, OPAMP4, OPAMP5, and OPAMP6.At this moment I try to initialize all four OpAmps. The first three work perfectly well, the initialization of OPAMP6 results in a problem. The Stat...
I'm using the STM32H562. I'm trying to start an ADC conversion using output compare on a specified channel during the middle of an up-down count of a timer.Timer used: TIM8 running at 250 MHz, generating a 20 kHz periodChannel: 4Timing: At the peak o...
All, My team is looking at designing a PCB around the STM32U5G9-DK2 development board and are running into some issues. The development board uses a flash memory IC "MX66LM1G45GXDI00" but the BSP example driver for the board only contains "MX66UW1G45...
Hello, Using Modbus master and slave communication, where Modbus master working fine, I have issue with slave device communication. Using HAL_UARTEx_ReceiveToIdle_IT() for receiving modbus frame, and HAL_UART_Transmit_IT() to transmit response. Curre...
I have STM32N6570-DK board and need to use very small sized camera ~1x1mm 30 fps with USB UVC interface for object detection applications. As the camera does not have dcmi/csi-2 interface, I am exploring how to use USB HS Host driver and UVC class dr...
Hi everyone,We are using STM32H755ZIT6 with external QSPI Flash in memory-mapped mode.After long runtime, we see an issue where the RTOS event returns resource unavailable (-3) even though the UART buffer has received complete data. We suspect it mig...
Hello, I am trying to configure my STM32H723ZG to be able to read the value of a few current sensors. My main concern at the moment is the speed at which I need to read these. I'm hoping to be reading upwards of rate of 20kHz. My questions are about ...
