我寫了一个EP2C8Q208C8 推ILI9327 3.2 " 400x240 TFT LCD 的程序 ,100MHz cpu clk, 想出全屏克色 , 可是全屏克色不成功 ,RUN AS HARDWARE "Hello from Nios II" 出到 ,  硬體檢查沒有問題 !!!  請各位看看程序有沒有問題 !!! #include "sys/alt_stdio.h" #include "system.h" #include "altera_avalon_pio_regs.h" void LCD_Writ_Bus(char VH,char VL); void Lcd_Write_Com(char VH,char VL); void Lcd_Write_Data(char VH,char VL); void Address_set( unsigned short x1, unsigned short y1, unsigned short x2, unsigned short y2); void Pant1(char VH,char VL); void delay_ms(unsigned short i); void LCD_Writ_Bus(char VH,char VL)   {     IOWR_ALTERA_AVALON_PIO_DATA(PIO_DATAH_BASE,VH);        IOWR_ALTERA_AVALON_PIO_DATA(PIO_DATAL_BASE,VL);           IOWR_ALTERA_AVALON_PIO_DATA(PIO_WR_BASE ,0); //write     IOWR_ALTERA_AVALON_PIO_DATA(PIO_WR_BASE ,1);//write } void Lcd_Write_Com(char VH,char VL) {        IOWR_ALTERA_AVALON_PIO_DATA(PIO_RS_BASE ,0);// rs     LCD_Writ_Bus(VH,VL); } void Lcd_Write_Data(char VH,char VL)    {     IOWR_ALTERA_AVALON_PIO_DATA(PIO_RS_BASE ,1);//rs     LCD_Writ_Bus(VH,VL); } void Address_set( unsigned short x1, unsigned short y1, unsigned short x2, unsigned short y2) {     Lcd_Write_Com(0x00,0x2a);     Lcd_Write_Data(0x00,x1>>8);          Lcd_Write_Data(0x00,x1);             Lcd_Write_Data(0x00,x2>>8);        Lcd_Write_Data(0x00,x2);             Lcd_Write_Com(0x00,0x2b);     Lcd_Write_Data(0x00,y1>>8);       Lcd_Write_Data(0x00,y1);           Lcd_Write_Data(0x00,y2>>8);        Lcd_Write_Data(0x00,y2);             Lcd_Write_Com(0x00,0x2c); } void Lcd_Init(void) {     IOWR_ALTERA_AVALON_PIO_DATA(PIO_LCD_RESET_BASE ,1); //output_high(pin_a5);     delay_ms(100);        IOWR_ALTERA_AVALON_PIO_DATA(PIO_LCD_RESET_BASE ,0); //output_low(pin_a5);     delay_ms(100);     IOWR_ALTERA_AVALON_PIO_DATA(PIO_LCD_RESET_BASE ,1);     IOWR_ALTERA_AVALON_PIO_DATA(PIO_CS_BASE ,1); //chip select     IOWR_ALTERA_AVALON_PIO_DATA(PIO_RD_BASE ,1); //read     IOWR_ALTERA_AVALON_PIO_DATA(PIO_WR_BASE ,1); //write     //output_high(pin_a1);     delay_ms(100);     IOWR_ALTERA_AVALON_PIO_DATA(PIO_CS_BASE ,0);     //output_low(pin_a3);    Lcd_Write_Com(0x00,0xE9);     Lcd_Write_Data(0x00,0x20);     Lcd_Write_Com(0x00,0x11); //Exit Sleep     delay_ms(100);     Lcd_Write_Com(0x00,0xD1);     Lcd_Write_Data(0x00,0x00);     Lcd_Write_Data(0x00,0x71);     Lcd_Write_Data(0x00,0x19);     Lcd_Write_Com(0x00,0xD0);     Lcd_Write_Data(0x00,0x07);     Lcd_Write_Data(0x00,0x01);     Lcd_Write_Data(0x00,0x08);     Lcd_Write_Com(0x00,0x36);     Lcd_Write_Data(0x00,0x68);     Lcd_Write_Com(0x00,0x3A);     Lcd_Write_Data(0x00,0x05);     Lcd_Write_Com(0x00,0xC1);     Lcd_Write_Data(0x00,0x10);     Lcd_Write_Data(0x00,0x10);     Lcd_Write_Data(0x00,0x02);     Lcd_Write_Data(0x00,0x02);     Lcd_Write_Com(0x00,0xC0); //Set Default Gamma     Lcd_Write_Data(0x00,0x00);     Lcd_Write_Data(0x00,0x35);     Lcd_Write_Data(0x00,0x00);     Lcd_Write_Data(0x00,0x00);     Lcd_Write_Data(0x00,0x01);     Lcd_Write_Data(0x00,0x02);     Lcd_Write_Com(0x00,0xC5); //Set frame rate     Lcd_Write_Data(0x00,0x04);     Lcd_Write_Com(0x00,0xD2); //power setting     Lcd_Write_Data(0x00,0x01);     Lcd_Write_Data(0x00,0x44);     Lcd_Write_Com(0x00,0xC8); //Set Gamma     Lcd_Write_Data(0x00,0x04);     Lcd_Write_Data(0x00,0x67);     Lcd_Write_Data(0x00,0x35);     Lcd_Write_Data(0x00,0x04);     Lcd_Write_Data(0x00,0x08);     Lcd_Write_Data(0x00,0x06);     Lcd_Write_Data(0x00,0x24);     Lcd_Write_Data(0x00,0x01);     Lcd_Write_Data(0x00,0x37);     Lcd_Write_Data(0x00,0x40);     Lcd_Write_Data(0x00,0x03);     Lcd_Write_Data(0x00,0x10);     Lcd_Write_Data(0x00,0x08);     Lcd_Write_Data(0x00,0x80);     Lcd_Write_Data(0x00,0x00);     Lcd_Write_Com(0x00,0x2A);     Lcd_Write_Data(0x00,0x00);     Lcd_Write_Data(0x00,0x00);     Lcd_Write_Data(0x00,0x00);     Lcd_Write_Data(0x00,0xc7);     Lcd_Write_Com(0x00,0x2B);     Lcd_Write_Data(0x00,0x00);     Lcd_Write_Data(0x00,0x00);     Lcd_Write_Data(0x00,0x00);     Lcd_Write_Data(0x00,0xeF);     Lcd_Write_Com(0x00,0x29); //display on           Lcd_Write_Com(0x00,0x2C); //display on     IOWR_ALTERA_AVALON_PIO_DATA(PIO_CS_BASE ,1);   } void Pant1(char VH,char VL) {     unsigned short i,j;     IOWR_ALTERA_AVALON_PIO_DATA(PIO_CS_BASE ,0);     Address_set(0,0,399,239);     for(i=0;i<240;i++)      {       for (j=0;j<400;j++)         {              Lcd_Write_Data(VH,VL);         }       }        IOWR_ALTERA_AVALON_PIO_DATA(PIO_CS_BASE,1); } void delay_ms(unsigned short i) {   unsigned short j,k;   for(j=0;j<i;j++)   {    for(k=0;k<1000;k++);   } } int main() {   alt_putstr("Hello from Nios II!\n");   /* Event loop never exits. */         Lcd_Init();   Pant1(0,0);   while (1);   return 0; }
