[GD32F450测试]6、采用ARMmbed[STM32F429工程]实验-TFTLCD驱显

zhjb1

实验5进行了采用STM32F429MBED工程开发GD32F450的尝试遇到不少问题，结果仔细分析用户手册和实际电路测量，基本上弄清楚了引脚的关系，pinNames.h的定义中的许多与实际不太符合，于是采样直接定义引脚的方式，实验从具有8位数据支持RGB565格式的并口2.2英寸TFTLCD做实验，简单介绍LCD的参数：2.2Inch TFT LCD，有200X176点分辨率，驱动芯片为S6D0128，8位数据线。为了程序简洁和易查看，单独写一个22lcd.h函数存放与LCD有关的定义和设置，代码如下，为了更好的说明，一段一段的写出：
首先定义并行总线，也可以定义为8位长：
BusOut busH(PA_7,PB_11,PB_12,PB_13,PA_2,PA_1,PC_1,PB_5);//LSB->MSB
定义控制引脚：
DigitalOut res(PC_13);
DigitalOut pdc(PA_12);
DigitalOut prd(PA_11);
DigitalOut pwr(PA_10);
DigitalOut pcs(PA_9);
定义外部变量：
extern int cor,colo;

至此，TFTLCD的控制就完成了。下边编写mainBusLcd.cpp：
连接函数：
#include "mbed.h"
#include "22lcd.h"
类变量定义：
DigitalOut led1(LED1);
int colo=0x003F,cor=0x0000;
//MAIN Programs
int main(){
float t0=1.0f;
ioInit();
lcdInit();
colo=0x0000;cor=0xFFFF-colo;
lcdClear();
while(true){
  led1=!led1;
  dispAll();
  wait(t0);
  colo +=0x037F;cor=0xFFFF-colo;
  lcdClear();
}
}
dispAll函数代码：
//Display All Code
void dispAll(void){
int i,j,k;i=0;j=0;k=0;
colo+=0x170F;
cont:
c2l(j,i*2,k%146);
if(j<21){j++;
}else{j=0;i++;colo+=0x0307;}
k++;
if(k<308) goto cont;
}
至此基于并口的TFTLCD的测试完成了。硬件连线见照片61，刷屏效果见照片62。
结果评测，清屏速度大约需要近3秒钟，填充满屏的时间差不多也是近3秒钟。这就是采用模拟并口方案的问题。因为还没有找到采用辅助功能AF的设置方法，利用芯片本身的LCD驱动方式可能是主要的原因。现在还在进行测试，主要是两个方向：加入触屏检测——尽管此屏有电阻触摸屏，但没有专用的触摸芯片，需要自己模拟触屏的AD信号来检测；第二是继续进行芯片AF功能的探索。
马上就到假期了，届时会有足够的时间进行测试。

可以尝试用DMA方式来直写显示存储区域，这样刷屏就快些。
快速刷屏是有技巧的。

谢谢！实际上看了手册，此款芯片内带TFTLCD驱动，只是还不会通过设置辅助功能AF13的模式来实现此功能。目前采用的是mbed的定义并口方式，应该不是最佳的方法，只鞥说是最简的方法。用这种方法在其他芯片上试过，需要较高的系统时钟才可以使刷新几乎看不出来。
