Posted on May 24, 2018 at 08:42 I am trying to set up a communication between my STM32F4 - Discovery with Open 407V-D development board and a peripheral using UART3 as a RS-485 bus. I have problem with my communication becouse Rx state of UART...
Posted on January 17, 2018 at 13:09A single STM32H7 SPI（SPI4） DMA master-slave full-duplex communication works very well, but when I add another SPI(SPI5) master-slave communication, the error rate will be high. What is the reason?
Posted on February 11, 2018 at 17:47 Hey everyone, Got a little issue that I'm a little confused on. I want to use a one pulse mode to output a pulse of length dependent on the input signal. So essentially, when the trigger goes off, I wan...
