[LPC54110开发板测试] 五、连接128x64黑白显示器
将四中的mainAdcPwm.c复制一个改名为mainAdcPwmLcd.c，打开这个文件进行编辑。
首先创建1个新文件夹，命名为incs，创建1个新文件，保存为128x64.h在这个文件夹中。在选项中默认此文件夹。在项目中将此文件夹加入，将此文件也加入。再在mainAdcPwmLcd.c文件的头部将此文件Include：
#include "128x64.h"
首先设定用GPIO1的8~11IO口作为串口LCD的控制口，打开board.h文档，增加以下语句：
#define lcdGpio 1
#define        sdat        8//PIO1_8
#define        sclk        9//PIO1_9
#define        sreg        10//PIO1_10
#define        sres        11//PIO0_11
打开mainAdcPwmLcd.c，在ioInit函数中增加以下语句：
//Define LCD CTRL Pins
Chip_GPIO_SetPinDIR(LPC_GPIO,  lcdGpio,sdat,true);
Chip_GPIO_SetPinState(LPC_GPIO,lcdGpio,sdat,true);
Chip_GPIO_SetPinDIR(LPC_GPIO,  lcdGpio,sclk,true);
Chip_GPIO_SetPinState(LPC_GPIO,lcdGpio,sclk,true);
Chip_GPIO_SetPinDIR(LPC_GPIO,  lcdGpio,sreg,true);
Chip_GPIO_SetPinState(LPC_GPIO,lcdGpio,sreg,true);
Chip_GPIO_SetPinDIR(LPC_GPIO,  lcdGpio,sres,true);
Chip_GPIO_SetPinState(LPC_GPIO,lcdGpio,sres,false);
而后打开创建的128x64.h文档，将下边的代码考入：
#include "board.h"
//128x64 LCD ASCII Codes
const unsigned char asc2[][8]={//8x6 Dots 32 to 127 + caratteri alfa_omega a seguire

打开mainAdcPwmLcd.c，在头上加入：
#include "128x64.h"
在后边加入：
void dispBase(void);
void dispMes(void);
Systick_Handler函数中将PWM周期语句改为[上节中的代码有误]：
if(duty0<98){ddut0++;}else{ddut0=1;duty0=0;}duty0+=ddut0;
if(duty1<98){ddut1++;}else{ddut1=2;duty1=0;}duty1+=ddut1;

Chip_SCTPWM_SetDutyCycle(LPC_SCT,4,Chip_SCTPWM_PercentageToTicks(LPC_SCT,duty1));
在main主函数循环语句前加入LCD初始化等函数：
lcdInit();
lcdClear();
dispBase();
在循环语句while中加入：
  dispMes();
在程序的最后加入：
//Display Based 12864

编译下载后从串口得到的数据见图51，图52，图53的LCD显示ADC和PWM周期值，左上的LED红和绿的亮暗反映了PWM1，PWM2的高低。

谢谢提醒，以后注意
