lcd12864 显示汉字图片 反白,是一个非常好的程序,可以和大家共享,-lcd12864 display Chinese characters picture anti-white, is a very good process, and everyone can share,

关于嵌入式PS2键盘的原理图，基于51单片机的工控键盘。很实用，包括程序，基于Keil的软件程序-On the embedded PS2 keyboard schematics, single-chip microcomputer-based industrial control keyboard 51. Very practical, including the procedures, the software program based on the Keil

该编码实现了简易智能小车循迹、记录金属个数、避障、寻光入库等功能-The coding realize the mini-mental vehicle tracking, recording the number of metal, obstacle avoidance, search features such as optical storage

pic单片机 DB4~DB7：在L CD中的作用，为数据线，DB0~DB2接地，DB3接高电平以完成对液晶的初始化。本Demo例子程序中，与单片机的RB2~RB5连接，用户使用其他的管腿时，只需修改#define部分。 RS为数据、指令控制线，与单片机的RB1连接，当RS为高电平时对LCD模块数据寄存器操作，当RS为低电平时对LCD模块指令寄存器操作； E为读写使能控制线，与单片机的RA5连接，每当E线向LCD模块发送一个正脉冲，LCD模块与单片机之间将进行一次数据交换； A、K分别是LCD模块背光的正负电源引脚，1-1所示，我们将用RC2控制背光，改变R29的值将改变背光亮度 R/W为读写选择线，在ICD2DEMO教学实验板中，R/W线接地，只做对LCD模块的写操作 -pic Singlechip DB4 ~ DB7: in the role of L CD for the data lines, DB0 ~ DB2 grounding, DB3 then high in order to complete the initialization of the LCD. Examples of this Demo program, with the single chip RB2 ~ RB5 connection, the user to use other s legs, simply amend the
