Posted on November 25, 2016 at 10:03 Generating USB CDC example in STM32CubeMX for STM32F103 it creates the following code inside USBD_LL_Init(): HAL_PCDEx_PMAConfig((PCD_HandleTypeDef*)pdev->pData , 0x00 , PCD_SNG_BUF, 0x18); HAL_...
Posted on December 09, 2016 at 12:57Hi all,I am new to microcontroller programming, and i recently started working on STM32F429ZIT6 MCU.I could able to program the Discovery board with sample programs(Blinking LEDs) with Kiel IDE, though i am facing...
Posted on November 29, 2016 at 03:44I have a working bit-banged implementation of swd, now I want to use the spi device. The protocol is a bit odd in requiring some short input sequences. Essentially, I'm using the spi device for everything that's...
Posted on October 07, 2016 at 13:13Hello, I am using STM32F070 microcontroller and current implementing USB CDC, I was searching a basic example of USB CDC on STM32F0, but not able to find any appropriate one, any help in this regard would be highl...
Posted on December 10, 2016 at 13:32Hello, I'm trying to use the usb peripheral embedded in stm32f407vgt6 as device. I connected D+(from host) to D+(of my MC) through 22Ohm resistor and D-(from host) to D-(of my MC) through 22Ohm resistor also Vbus(...
Posted on December 08, 2016 at 22:32Hi,I am trying to build something and currently doing some evaluation and development with 32L476GDISCOVERY Discovery Kit with STM32L476VG microcontroller.What I am trying to achieve at the moment is output of int...
Posted on November 09, 2016 at 18:55HelloAs i inspected through assembly instructions, it is possible to read 16 bits gpio port with 2 cpu cycles and write with 4 cpu cycles, beside of electrical considerations, is it possible to achieve reading and...
Posted on November 11, 2016 at 14:20Hello,I have one question. I have two CPUs (STM32F407 + STM32F103) and I need to ''share'' (or better say ''synchronize'') 64 bytes between these CPUs every 100us. So every 100us the CPU must send 64 bytes to anot...
Posted on November 11, 2016 at 18:08Hello. I have got stm32f746 and I make project with cubeMX. I want to use SPI4, SPI5, SPI6 as fullduplex master with 50Mb/s baudrate. Then I try to HAL_SPI_Transmit(&hspi4, pData, 1, 30000); in while(1) cycle. ...
Posted on November 29, 2016 at 05:51 Hello! I am currently trying to send a sine wave through the DAC. I've tried both using the std peripheral libraries and stm32cube, but to no avail. The frequencies and amplitude of the measured sine w...
