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...
Posted on December 07, 2016 at 22:19Hi, I want to start off my STM32F745VET6 running on the PLL sourced from the 16MHZ HSI oscillator. I need to run some I2C code to initialize an external multi-output high accuracy clock generator chip where one of...
Posted on November 14, 2016 at 08:53Hello,On my currently developing device and I issued a problem. I'm using CubeMX 4.17, F0 package 1.6 and F4 package 1.13.1.I developed the code for F4 - SPI1 communicating with NRF24L01+ module using HAL library ...
Posted on December 08, 2016 at 23:47I'm attemping to read the data from a 8 bit SPI bus transfer. It seems the data is getting into the shift register, but not transferring into the DR register after clocking the data. I have confirmed the RXNE and ...
