1. Introduction Recently, I received the AI8H2K12U microcontroller sent by STC company. According to its datasheet, this microcontroller has built-in USB to serial port firmware, and it does not require USB driver installation. Furthermore, it can be paired with an external power control circuit and can work with STC’s ISP software to form the programming … Read more
01 Speaking of microcontrollers, we cannot avoid the 51 series. I remember the first microcontroller I encountered in college was the AT89C51. I believe many people started learning about microcontrollers from here, right? Of course, the AT89C51 is rarely used now. However, another brand of the 51 microcontroller is still very popular, which is the … Read more
In electronic technology, the microcontroller unit (MCU) is undoubtedly the core “brain” embedded in various smart devices, making it extremely important and highly sought after in the market. Driven by high demand, many people choose to become microcontroller engineers. So, how should a beginner in electronics choose a microcontroller after learning and becoming proficient? 1. … Read more
To start, why do I write IIC instead of I2C in my article? Because they are the same thing, and it’s easier for me to write as IIC Today, we will look at how to use IIC in the STC library functions. There are three sets of pins available for us to choose from, and … Read more
Hello everyone! Today I want to share a particularly interesting topic – FastCGI. Are you still worried that C language cannot develop web applications? With FastCGI, C language can easily handle web development! Let’s explore this powerful interface protocol together. What is FastCGI? FastCGI is an upgraded version of CGI (Common Gateway Interface), allowing C … Read more
