My processor board uses STM32H743V. The Ethernet chip is KSZ8081, MII mode. I also use AZURE RTOS and NetX. I tried using CubeMX to generate an application, but it always gives me some error when I compile the program. I tried different combinations,...
Hello everyone.Recently I started to use LL library & STM32CubeIDE to do my project.I'm trying to use DMA to transfer data which converted from ADC multiple channel from peripheral to memory.the DMA data is total wrong, converted data is almost the s...
Hello there,I am currently working on STM32L452RET6 microcontroller in which I am trying to flash hex file using software STMFlashloader Demonstrator via UART protocol.When I shift BOOT0 pin to high (3.3v), program goes into bootloader mode, and nBO...
I'm trying to use FATFS on NUCLEO-F401RE to write a file into the SD Card.I generated the project into cube MX and added thi code before the while(1) loop: /* USER CODE BEGIN 2 */ temp = f_mount(&StrutturaCtrFS,"",1); if(FR_OK != temp){ while(...
Dear Customer SupportI'm using the USB CDC class (Virtual COM Port) on STM32H7.When I unplug and plug the USB cable during comport communication, occasionally, the device manager display shows "Unknown USB device (device descriptor request failed)".I...
Hi,I want to use my own custom usb device class base on usb core provided by ST. Inspecting the code, I found that "DataIn" and "DataOut" callback functions provided by the class to usb core are called at the END of the data in or out stage... Callin...
My program has the option of sleeping for a period using the RTC to wake or sleeping until the wakeup pin is set high. Both these functions work perfectly if I talk to the outside world using a uart.However, I configure CDC as a serial port SLEEP doe...
Hi,I am trying to understand the interrupt vectors for the USB interrupts for the STM32G4. In the reference manual (RM0440) it shows that there is a USB_HP and USB_LP interrupt. However, I cannot find any mention in the USB interface description that...
Hello everyone here, I have a STM32L43x µC and I wish to read the Memory size when I am in Bootloader mode. I tried using the function Read Memory command to read the register at address (Base address: 0x1FFF 75E0) which contains the Memory size. Unf...
Hello community,I'm currently having issues or perhaps not fully understanding the procedure of writing data to the MCU bank 2 and then switching to this bank to run the program from bank 2.My setup for now is using a custom protocol for sending the ...
