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

单键遥控码学习控制器，很好用的一个小程序，绝对原创，对了解单片机通讯的用户是一个很好的参考程序-single-button remote control codes learning controller, a very good use of small programs, absolute originality to understand SCM communications users is a good reference procedures

l298调 速 程 序 常规的接法是这样的，EnableA接PWM信号，Input1输入正反控制信号， Input2是Input1经过反相以后的信号。L298的电平是与TTL电路相兼容的，一般是超过2.5V就为高电平。假如Input1为高电平时电机正转，那么低电平时就是反转，PWM信号控制电机的转速。 _________________ -l298 procedures conventional speed connection that is the case, EnableA then PWM signal, Input1 input positive and negative control signals, Input2 is Input1 through after RP signal. L298 level is compatible with TTL circuits, and is generally more than 2.5V for the high. If Input1 is high when the motor is transferred, then that is when low-level inversion, PWM signal to control motor speed. _________________
