Keil will have a line after compiling: program size:code=xxx ro-data=xxx rw-data=xxx zi-data=xxx
Code represents the execution of the codes, and all functions in the program are located here.
Ro-data represents read-only data, and the global
Generally, the serial port sends data by character, which is simple to send data. You can directly use the "Serial Port debugging assistant" to receive data and facilitate debugging.If binary data is used to send data, the sent content is greatly

PS/2 Overview
PS/2 is divided into master and slave devices. The master device uses female sockets and male plug from the device. currently, the widely used PS/2 keyboard and mouse work in the device mode. PS/2 interface clockIt is an open-collector
First, I declare that I only implement some of the functions, and none of the functions that are not mentioned are implemented by default.

Comparison of main ZigBee chip vendor's ZigBee solution competitivenessAt present, there are major ZigBee chip vendors (2.4 GHz), including Ti/chipcon, Ember (ST), jennic (), Freescale, and microchip.Currently, ZigBee technology provides three methods:1) ZigBee RF + MCU, such as Ti CC2420 + MSP430, freesclae mc13xx + GT60, microchip mj2
task, and it's a good idea to browse the ENC28J60 manual before you start. In addition, we need to read the TCP IP related knowledge carefully, recommend a book "Embedded Internet TCP/IP foundation, implementation and application."
