Please give me some advice: My goal now is to output a high level signal from the microcontroller, so that 9013 is turned on, relay K works, and the AC motor runs. This function has been realized, but...
I downloaded a software, and when I tried to install it for the second time, it told me that I had already installed it once and wouldn't let me install it again. I thought maybe the software read the...
[i=s] This post was last edited by azhiking on 2014-11-18 21:52 [/i] Since the evaluation board has an IO port expansion, you can only choose between hardware SPI and I2C. Since the speed of I2C is re...
UART, I2C and SPI are the three most commonly used communication protocols in microcontroller systems. We have already learned the UART and I2C communication protocols. In this class, we will learn th...
