Posted on June 05, 2015 at 23:41I'm using SPI3 on an STM32F4, chip select toggled in software. I have a function that sets the chip select low, sends data and than pulls up chip select pin.Now I've noticed that when this send function is being calle...
Posted on June 07, 2015 at 03:36Hello,My STM32F103 is working as motor driver and work with pwm as an input runs at about 500hz or 2 ms duty. An incremental encoder is connected as a speed reference of the motor output.Pin connection is as follows.E...
Posted on June 07, 2015 at 19:47hi everyone i m going to interface encoder with motor the encoder is working perfectly and counting up to 0xFFFF in clock wise direction but when i rotate in counter clockwise direction it,s counting from 0 but from ...

Posted on June 03, 2015 at 09:42 Hello dear members of forum, I would like to use a FM24C256 ram of RAMTRON ( http://www.kosmodrom.com.ua/data/memory/FM24C256ds_r3.1.pdf). I have tryed to write program for it but It do not work. When I...
Posted on June 06, 2015 at 12:39I am working on Data aquisition system using stm32f401 , I have configured ADC . but in configuration of USB interface as VCP , there are linking errors , please help me out in this regard ..
Posted on June 04, 2015 at 11:53Hi, I am using the STM32F407 SPI TXE and RXNE interrupts. The ISR checks if there is data to transmit or if any data is received. The data to be transmitted is filled outside the ISR and the TXE interrupt and CS is en...
Posted on June 05, 2015 at 00:09I've used CubeMX to init SPI. There is a struct called hspi3 created by the init code which holds settings for SPI. I would like to use SPI library in a C file I've written (DAC driver) but I can't because HAL_SPI_Tra...
Posted on June 05, 2015 at 09:41HelloIf i want to connect output of an ADC(analog to digital converter) to two different ports, e.g. GPIOA and GPIOB, and to modify this selection by means of software code(no hardware modification needed), how is it ...
Posted on June 05, 2015 at 18:28I am looking at implementing a 3 phase BLDC using hall sensor inputs and motor commutation on timers on the discovery 407 board. I have reference of http://www.mikrocontroller.net/articles/STM32_BLDC_Control_with_HAL...
