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...
I have been trying to get values from an HCSR-04 sensor, but I only get garbage values. I debugged it and saw that my code doesn't clear the UIF flag of the TIM2 SR register. Could this be the cause of the garbage values? I tried the sensor with an A...
Hi,I have started my hand-on experiments of FreeRTOS using stm32u575 uc with stm32u575zi-q nucleo board as non secure.I have created 2 task and their handler. With the help of seial viewer, printed some messages.While executing the code,it does nothi...
Hellois it possible for the microcontroller with USB OTG to download the program memory from the USB stick itself?In other words, change the firmware simply by connecting a USB stick with a .bin file and perhaps by resetting the component.So far I ha...
Hi STM Team,I need to access test.wav audio file from External SPI Flash memory.Is there is any file system library to mount spi flash memory as file system?I am using Nucleo - G070RB.Is there is any microcontrollers with library that support externa...
Hi,I am a beginner in STM32. I am doing a POC to read the coordinates of the touch sensor tsc2004 with ili9488 LCD driver. My custom board uses STM32F429i disc board. But I am using an external LCD driver rather than ili9341 (built-in). Based on the ...
Hello,When I try to read USART status register (RXNE bit), the execution stucks upon while loop which means no data have been readen: char uart2_read(void) { while(!(USART2->ISR & USART_ISR_RXNE)){} return USART2->RDR; } I think I initialized eve...
Hi there,I am seeking some guidance regarding the connection of the STUSB1602 to the STM32L031G6U6 microcontroller for a low-power application with a small footprint.Currently, I have already connected the STUSB1602 to the microcontroller using the I...
Hello, I'm trying to determine the source of the wakeup flag, whether it's the power being turned on or the trigger of wakeup pin 2.So this is my shutdown function:After i changed my shutdown function : when I try to determine the reason for the w...
Hello ST Community,I am currently working on a project using the Nucleo-H753ZI without an RTOS, and I have followed a tutorial by Controllers Tech to set up TCP/Ethernet. I am using Static IP assignment.I can Transmit and Receive data though Hercules...
Hi,I would like to create a gamepad that is recognized by the computer (windows), and have the Virtual Com Port (CDC) to send en receive data with the computer. For that, I want to create an USB Composite with HID+CDC. I found an exemple on this webs...
