Hi all,I'm having trouble getting reliable SPI communication using the STM32N6570-DK board. I'm using SPI5 with DMA, but the data I receive is only correct about 50% of the time.I'm expecting to receive the value 1025, but often get corrupted values ...
I am beginner in using STM32 boards I am working with stm32f411re board with that I will use sim900a gsm module for internet connectivity and then mqtt protocol to send data to AWS cloud. So, when I am using paho mqtt library paho.mqtt.embedded-c/MQT...
USB HID Endpoint Size Challenge - My Experience Issue Description I'm experiencing an issue with USB HID endpoint sizes in my firmware running on an STM32U5 microcontroller with ThreadX RTOS and USBX middleware. Specifically: My host is sendin...
I'm working on some code that has a boot loader and an application. At the moment I am using one linker script for each, which means I have to make sure I keep them in sync. Is it possible to configure the build for (e.g.) the boot loader so that .bo...
I have set up a DMA on an I2S device with an STM32H503CBU6. The idea is, that the DMA runs continuously on a single bufferaddress (one word, containing the left and right channels for the external I2S-DAC). When the DMA transfer of that 1 word is com...
Hi all! What event is generated if the MCU receives a data packet equal to the buffer value passed to the HAL_UARTEx_ReceiveToIdle_IT (or HAL_UARTEx_ReceiveToIdle_DMA) function? There will essentially be two events: HAL_UART_RXEVENT_TC and HAL_UART_R...
The STM32 HAL is good and simple. It's highly appreciated that I am not forced to use a certain build system. But there is one thing that drives me crazy: The STM32 HAL has lots of weakly defined symbols. That forces me to put any strong symbol overr...
Hello ST Community, I noticed that STM32L5 series (e.g., STM32L552) does not currently have official FDCAN support in Zephyr. The stm32l5.dtsi does not define an fdcan node, and there are no corresponding bindings or support in the driver layer for t...
Hello dear supporters,I had some issues setting up my STM32G0B1CET6N as USB Communication Device Class (Virtual Port COM). Clock Source for the USB is the internal "HSI48 RC" oscillator, designed for USB application. What happened? I used the defaul...
Hi. I am currently using the stm32u545ret6q mcu. Looking at the RCC of reference documentation(RM0456) it says that it has MSIS hardware autocalibration, but the example code(AN5676) only shows how to adjust the trimming value. Do you have...
