（5）测试代码

<pre>
<code class="language-cpp">void LcdTest(void)
{
LcdInit();//LCD初始化
LcdFill(0,0,LCD_W,LCD_H,BLACK);

LcdShow16x16Hz(32, 0, 0, YELLOW, BLACK);
LcdShow16x16Hz(48, 0, 1, YELLOW, BLACK);
LcdShow16x16Hz(64, 0, 2, YELLOW, BLACK);
LcdShow16x16Hz(80, 0, 3, YELLOW, BLACK);

LcdShowString(32,24,"GD32L233",BLUE, BLACK,16);
LcdShowImage (14,40, 100, 93, gImage_zan);//winxin_gImage_x
