在無字庫LCD12864上面寫字的時候，寫了八個字后，后面的不顯示了，然后一步一步調(diào)，發(fā)現(xiàn)超過8個就不顯示了。
顯示程序如下：
void lcd_display_chinese(uchar screen,uchar page,uchar col,uint mun)
{ //screen:選擇屏幕參數(shù)，page:選擇頁參數(shù)0-3，col:選擇列參數(shù)0-3，mun:顯示第幾個漢字的參數(shù)
int a;
mun=mun*32;
select_screen(screen); //選屏
W_CMD(0xb8+(page*2)); //頁：一頁8點(diǎn)行
W_CMD(0x40+(col*16)); //列：一列1點(diǎn)列
for (a=0;a<16;a++)
{
W_DATA(chinese[mun++]); //一個字16x16
}
W_CMD(0xb8+(page*2)+1); //兩頁一行
W_CMD(0x40+(col*16)); //行列指針自加1
for ( a=0;a<16;a++)
{
W_DATA(chinese[mun++]);
}
}
主函數(shù)如下：
void main()
{
initLCD(); //LCD初始化
clear_screen(0); //LCD清屏幕
lcd_display_chinese(1,0,1,0); //LCD顯示漢字///一
lcd_display_chinese(1,0,2,1); //LCD顯示漢字//
lcd_display_chinese(1,0,3,2); //LCD顯示漢字//
lcd_display_chinese(2,0,0,3); //LCD顯示漢字//
lcd_display_chinese(2,0,1,4); //LCD顯示漢字//
lcd_display_chinese(2,0,2,5); //LCD顯示漢字//六
lcd_display_chinese(2,0,3,6); //LCD顯示漢字//
lcd_display_chinese(1,1,0,7); //LCD顯示漢字//八
lcd_display_chinese(1,1,1,8); //LCD顯示漢字//
lcd_display_chinese(1,1,2,9); //LCD顯示漢字//
lcd_display_chinese(1,1,3,10); //LCD顯示漢字//
lcd_display_chinese(2,1,0,11); //LCD顯示漢字//
while(1)
{
delay(10);
}
字庫程序如下：
