Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
In an inherited code I see LL_GPIO_Init() being called with pin definitions (LL_GPIO_PIN_xx) OR-ed together, presumably to define multiple pins of the same port to the same settings, in one call of the function.The documentation (doxygen header) to L...
Hi! I read from many posts that it's possible to use FAFTS with this board, but I can't get the project to compile without errors. The weird thing is that errors appear between the files of the libraries themselves (attached photo). Variables that ar...
Hello Community,I'm working on a storage module using SDcard for my project.The chip I'm using is STM32H743XIH6.At present, the SD card has been successfully read and written in the polling (ordinary) mode. However, I have never succeeded in reading ...
I wonder why I have data in the buffer when my sample rate is 30KHz and 0 when the sample rate is 50KHz. My code:/* USER CODE BEGIN Header */ /** ****************************************************************************** * @file ...
I configured dual DAC synchronous sampling，DMA is in normal mode for data transfer.When the timer frequency of the ADC is 10KHz, the main cycle can print serial port information, but when the timer frequency is 50KHz, the main cycle does not print AD...
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...
