The system requires three clocks, 36M clock as MCU clock source; 25M clock to drive Ethernet chip; 10M clock as the clock source of wireless transceiver module. The design process is as follows: 1. Op...
This is the program for the ds1337 clock chip. Is interruption used (does the RTC send an interrupt to 430 once every second??) How to initialize the time and how to use it? c file: #include "Main_Pro...
I mentioned the light control function when I submitted the proposal, but unfortunately I was too busy and omitted it. Today, when I was looking at the circuit diagram I drew before, I suddenly had an...

With the advent of the new economic era represented by the Internet, PCs have lost their former glory, and smart 3C products (Computer, Communication and Consumer) will set off a new wave. As one o...[Details]
In recent years, with the rapid economic growth, wireless communication has developed rapidly. Since spread spectrum signals have the characteristics of anti-interference, confidentiality, anti-det...[Details]
In the process of RF transceiver application, adjusting the processing gain (PG) of the direct sequence spread spectrum communication system (DSSS) can obtain excellent anti-noise performance, whic...[Details]
Portable products are generally powered by batteries. Due to cost and size considerations, there is a trend to reduce the number and size of batteries used in design. If the number of batteries is ...[Details]
1 Introduction
In many communication systems, the base station usually sends a training sequence for the terminal to synchronize with the system. The synchronization here includes time syn...[Details]
introduction
In simple single-chip microcomputer application systems, the foreground/background system is widely used. The application is an infinite loop, in which the corresponding funct...[Details]
