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...
Hey,I tried to follow all the steps of this thread as good as possible. Still I have a faulty SAI Perpheral. The Problem is that the generatet FSYNC and BCK are too low. They are both also dependent on the PLL Frequency. For example if i set IC7 so t...
I am sending and receiving MQTT messages. My problem is that after normally working it could be that one ACK is not been sent out to the broker which prevents him to send anymore messages to my board.I recognized that by watching the packets on the b...
I'm using an STM32U5A9J-DK and I've followed this guide step-by-step https://community.st.com/t5/stm32-mcus/how-to-redirect-the-printf-function-to-a-uart-for-debug-messages/ta-p/49865From the docs https://www.st.com/resource/en/user_manual/um2967-dis...
Hi everyone,I am currently running the DCMIPP_Continuous mode example from STM32N6Cube firmware v1.2.0. However, I am getting stuck at the function call:HAL_result = HAL_RCC_OscConfig(&RCC_OscInitStruct);RCC_OscInitStruct.OscillatorType = RCC_OSCILLA...
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,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...
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 everyone,I’m working on an STM32F103 microcontroller using CAN in polling mode (without FreeRTOS).From my testbench, I transmit 16 CAN messages cyclically every 100 ms.Each message has a unique CAN ID.My goal is to:Receive all 16 messages withi...
