Hi, today I found an pretty unusual bug while doing some projects with the USB CDC, my code, out of the blue, showed hundreds of errors, after some diggins, me and a friend, found out that in the usbd_def.h, the TypeDef of "USBD_StatusTypeDef" was ch...
I encountered a problem when trying to send more than 5 bytes of data using the FMC. // impossible example -- #define SD_DATA (*(volatile unsigned char *)0x60000001) SD_DATA = 0x01; SD_DATA = 0x02; SD_DATA = 0x03; Using this method, data i...
Hi,part of the project I am working on, I have been asked to add an external device to a vending machine. It is an age-recognition system that would interface with the main controller via USB. But apparently uses HTTP protocol over USB if I understan...
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...
Hello STM community, I am currently working on a project that involves connecting a PS5 controller to an STM32 microcontroller. I would like to inquire about the feasibility and potential approaches for achieving this integration. Specifically, I am ...
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...
