320x240彩屏液晶繪圖程式

        本文為利用9325TP的彩色TFT LCD螢幕，進行撰寫擴充的不同圖形的繪圖程式，文中的原始碼只將有關的幾種繪圖程式寫出，其他的如ＵＡＲＴ，　ＴＩＭＥＲ等程式，就不在此說明了，請參考過去已經發表的文章，請見諒。

        使用的ＭＣＵ是ＳＴＣ１６Ｆ２Ｋ６０Ｓ２—２８Ｉ，設定的頻率是內部２７。０００Ｍｈｚ，彩色螢幕是　ILI Technology Corp.　a-Si TFT LCD Single Chip Driver　240RGBx320 Resolution and 262K color，

 

以下是程式的範例

        簡單說明，由亂數決定將繪圖的圖形，０＝矩形圖，１＝線條，２＝三角形，３＝圓形，而繪製圖形時的位置與顏色，也是由亂數產生，
