三、使用PIC公司的触摸库做触摸处理
C与汇编混合编程
--------------------------------------------------------------------------------------------------------------
看到PIC单片机就感到亲切，今天开始对PIC16lf1936编程仿真，仿真器PICKIT3。
--------------------------------------------------------------------------------------------------------------
Mplab IDE的使用
一、接入PICkit3出现Target Device ID (00000000) does not match expected Device ID (00002460)
这是仿真头与线路板连接不正确。
二、首次使用pickit3出现PK3Err0040
PK3Err0040: The target device is not ready for debugging.Please check your configuration bit settings and program the device before proceeding.
解决办法：在这里勾 选：Debugger>Settings>Program Memory>Automatically 的 “Program after successful build”项即可在每次成功后自动下载代码到Flash并进入调试就绪模式。
三、接入PICkit3烧录时要设置电源
PK3Err0045: You must connect to a target device to use PICkit3.
Programmer>Settings>Power中设置
四、maplab的输出窗口看不见
1、在设置这个功能的时候，准备把output窗口移到下边缘，没想到移动过头，移动到电脑桌面的最下方（移到下发看不到的位置去了），然后output窗口就不见了，调不出来，在view里面勾选了output或者取消，编译文件，甚至重新启动电脑，output窗口都不出现了！
右击任务栏－>解除锁定任务栏－>拖动任务栏到右边就可以看到被隐藏的窗口了
2、隐藏在整个窗口的下方
右侧是有进度条的。
将output移上去，右侧就没有进度条了。

Mplab X IDE的使用
图1 驱动切换与安装
图2 批量烧录
一、接入PICkit3提示找不到工具，为驱动没有安装
打开如图1 MPLAB drive，如下图设置，点"Apply Changes"即可。
二、microchip官网下载XC8编译器
--------------------------------------------------------------------------------------------------------------
实践
一、端口控制
完成三件事：１、仿真部分全部正常；２、配置字设置无误；３、内部晶振正常，端口操作正常
#include "pic.h"
void delay_long(unsigned int uiDelayLong);
void main()
{
OSCCON = 0xeb;//禁止4X PLL，内部4MHz时钟源
TRISBbits.TRISB3 = 0;//设置RB5端口为输出
TRISCbits.TRISC4 = 0;

}
}
