Three weeks I am trying to cope with a mysterious problem. I will begin from general description and then dive into details. The MCU is STM32F103RFT6, HAL and C++ Wrapper for FreeRTOS 10.2 are in use. So, I have only one task running (not counting I...
Hello, I am using NUCLEO-F429ZI and set usb as com vcp. I am able to connect board to PC without any problem, but ST doesn't provide specified pc driver for stm32 VCP. In my pc, I can see general vcp com port in PC, is it possible to read parameter ...
Hi everyone ! I have a problem . I started a triple mode ADC and I wanna send ADC data via usb (CDC) FS .But my problem is , when my input length of HAL_ADCEx_MultiModeStart_DMA() is more than 256 , my sent_bytes[] numbers won,t be correct . but for...
I am trying to send data to the console using the "echo" method.static int8_t CDC_Receive_FS(uint8_t* Buf, uint32_t *Len){ CDC_Transmit_FS(Buf,*Len); USBD_CDC_SetRxBuffer(&hUsbDeviceFS, &Buf[0]); USBD_CDC_ReceivePacket(&hUsbDeviceFS); return (USBD_OK...
I am using stm32f072rb discovery board. I am connecting memory card using SPI. I want to use USB MSC and want to see the SDCard data on PC. How can I do that? I used the USB_MSC_Standalone example but not working. I am attaching the code. The disk is...
Hello,I just started working with STM32f767zi board. I'm doing TCP Ethernet communication using lwip RAW API. I could be able to start the communication with the host. But the problem is, in my forever loop I put MX_LWIP_Process() function. If I put ...
i want to know which drivers require less space(small HEX FILE) and good optimization HAL or LL driver?
I am using stm32f072rb discovery board... I want to use SRAM as mass storage... I am attaching the project... I am getting the memory on windows but on the format it shows an error like "windows is unable to format".
I'm working on an application that requires Ethernet on an STM32F765 chip and there are two options to attach an Ethernet PHY to the MCU: RMII and MII. Deciding on which interface to use has led me to a post that mentioned RMII having issues on STM32...
my program is stuck below this pointso never received ethernet frame if(((heth->RxDesc->Status & ETH_DMARXDESC_OWN) == (uint32_t)RESET))in HAL_ETH_GetReceivedFrame function
