Hello, I have some problems with my STM32F446RE (Nucleo-64 )and terminal program (as puTTY and so on).I connected it by its usb connector (CN1) and it was recognized as Virtual Port: Well!So I opened STM32Cube MX and set:-STM32F446 board.-USB_OTG_FS,...
I encountered a complex problem and I don't understand where should I start untangle it.What I want to do:I have a buffer (allocated in SRAM_1) that filling up with DMA. DMA pass TIM2_CCR1 value into buffer's cells.Flow:unsigned int dma_buffer[15360*...
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?
