Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Can someone please write me a few lines to enable my code to receive an interrupt as a byte is coming?For the life of me I cannot find any code examples. All I can find is application notes that go on and on about the capabilities of the STMicro SPI....
Posted on March 21, 2018 at 13:27Hello there,I am using the STM32L4 family MCU. In my hardware design, only after the USB cable is connected the voltage is applied to the VDD_USB pin of the MCU. At no USB connection this voltage is not present.As a ...
Posted on January 26, 2017 at 14:16Hi,I am struggling to make a vendor device, that sends request on control pipe endpoint 0 out (EP0_OUT), I can receive the request correctly, but I can't send an ACK back (zero length packet). I have tried USBD_Ctl...
Posted on February 21, 2016 at 03:02Hello,We are working on a migration from the TI Stellaris products to the STM32F42xx. The one thing I haven't been able to find yet is a way to duplicate how we allow firmware upgrades. We use the USB-device por...
Is it possibile to obtain the equivalent of HAL_I2C_Mem_Write(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint16_t MemAddress, uint16_t MemAddSize, uint8_t *pData, uint16_t Size, uint32_t Timeout) in Low Level like function?
I am not sure if this is STM32 related question but I noticed one strange behaviour while using STM32 devices with USB composite device and composite device only.So my device is composite device with three different interfaces (HID). I am transfering...
We have a new STM32F411E-DISCO kit and are trying to run the Audio playback and record application.I have imported the SW4STM32 project but I keep getting errors with missing files - usually the following:stm32f411e_discovery_accelerometer.c..\Common...
Hi,do you prefer the low layer (LL) APIs or direct register access by means of the CMSIS? Why do you prefer your choice?
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...
