Greetings,I am currently using for the STM32F469ZI the build-in USB-DFU-Bootloader. So far the bootloader is working well. The bootloader always register itself in Windows 7 as "STM Device in DFU Mode". Is there a possibility that this name can be ch...
Dear Sir,Now I am using HAL library ( STM32Cube_FW_L1_V1.8.0)after setup USART 3, and after running, in some case, I need to disable the transmit interrupt by using__HAL_UART_DISABLE_IT(&UartHandle, UART_IT_TXE);But then if I need to re-transmit som...
I'm using NUCLEO-446ZE Host to access USB KeyboardMy cubeMx version STM32Cube FW_F4 V1.21.0I configured all clock and 48Mhz for USB via PLLSAIPMain core run on 180MhzWhile connecting Keyboard I'm able to detectWhile accessing k_pinfo = USBH_HID_GetKe...
How I can speed up USB VCP transmission? I have already set CDC_DATA_FS_MAX_PACKET_SIZE to 256.
Hi .I use CDC to transmit data to computer .I want to transmit big array to the computer using CDC_Transmit_FSwhat is the maximum buffer length that support this function ?this is my code:CDC_Transmit_FS((uint8_t *)buffer,(uint16_t)73728);but some am...
There was a change in the HAL_PCDEx_BCD_Callback() function defined in usb_device.c that, by default, results in the code not handling the PCD_BCD_DISCOVERY_COMPLETED notification.The switch statement for processing the state changes in the new user ...
Im trying to send udp packets back and forth using a Nucleo F429zi board. As I debug the program, I get 0 for all the other errors, but for udp_sendto() I get a -4. I found that this error code corresponds to ERR_RTE, operation in progress error, but...
I implement a SPI slave protocol on a STM32F0 board.After the master as transferred a command to the slave, it polls in regular intervals by reading one byte off the slave until the slave sends a start byte of value 0xFF.in the attached screenshot, t...
I can't find an svd file for the STM32F415 https://www.st.com/resource/en/svd/stm32f4_svd.zip does not contain a svd file for the STM32F415 series is one of the contained ones 100% compatible? STM32F401.svd* STM32F405.svd* STM32F407.svd* STM32F41...
I am currently using a STM32F105 MCU configured to USB Device_Only mode by STM32CubeMX, including middlewares for communication device class (VCP).Since I had to use the PA9 pin as an alternate function (USART1_TX), I've planed to use another GPIO fo...
