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...
