Hello. I'm using a custom board with STM32F105RBT6. I used the MX_USB_HOST_Init() funtion to configure the host usb in mode usb_otg_fs. The problem is that some USB keys don't work (the USBH_Process() function can't go further the HOST_ENUMERATION st...

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...
Hey all, I'm attempting to implement the EEPROM emulation library into a pre-existing project with little success. I've added the eeprom.c file to the project as well as the header include to the main.c but even prior to implementing the code, attemp...
Hi!Using STM32F105 microcontroller.I've created a clear USB CDC project with STM32CubeMX (5.0.1).It works well when connected to Windows 7 host machine, Virtual com port is appearing on Device Manager.But when i connect to macbook I've got "HS01@1410...
Default USB settings for command packet size is 8U (CDC_CMD_PACKET_SIZE), meanwhile, if we want to change "hardware flow control" flags, we need to send 10 bytes command packet. (for 32F103)If CDC_CMD_PACKET_SIZE is redefined in cubeMX package, I rec...
i use STM32F107+LWIP(2.0.3)+freeRTOSI wrote the program with the help of the following document :https://www.st.com/resource/en/user_manual/um1713-developing-applications-on-stm32cube-with-lwip-tcpip-stack-stmicroelectronics.pdfAfter connecting the c...
In stm32f1xx_ll_gpio.h, LL_GPIO_AF_EnableRemap_SWJ(), LL_GPIO_AF_Remap_SWJ_NONJTRST, LL_GPIO_AF_Remap_SWJ_NOJTAG(), LL_GPIO_AF_DisableRemap_SWJ() all use SET_BIT(AFIO->MAPR, AFIO_MAPR_SWJ_CFG_xxxxx);which is incorrect, as SET_BIT is #define SET_BIT(R...
Posted on October 22, 2017 at 16:13I want to use ' HAL_UART_Transmit_DMA(); ' to send data in DMA mode like this : char str_Hello[]='Hello\n'; HAL_UART_Transmit_DMA(&huart1,(unsigned char *)str_Hello,strlen(str_Hello)); HAL_Delay(500);But ...
I have STM32F103C8T6 development board (like this: https://www.rogerclark.net/wp-content/uploads/2014/11/STM32Mini.jpg) which can be programmed by USB interface. I programmed it several time before, but now I can't do this. When I connect it to the P...
