- 通過(guò)瑞佑的液晶控制芯片可以很容易實(shí)現(xiàn)半透明效果、淡入淡出效果，具備該功能的型號(hào)有RA8889,RA8876,RA8876M,RA8877,RA8871M,RA8873M等等，僅需要單片機(jī)控制,代碼簡(jiǎn)單易用.
代碼舉例:BTE_Alpha_Blending(0,2736,500,300,0,2736,1024,0,0,2736,1100,400,200,200,16);

函數(shù)使用說(shuō)明:void BTE_Alpha_Blending
(unsigned long S0_Addr //Start address of Source 0,unsigned short S0_W //image width of Source 0 (recommend = canvas image width),unsigned short XS0 //coordinate X of Source 0,unsigned short YS0 //coordinate Y of Source 0,unsigned long S1_Addr //Start address of Source 1,unsigned short S1_W //image width of Source 1 (recommend = canvas image width),unsigned short XS1 //coordinate X of Source 1,unsigned short YS1 //coordinate Y of Source 1,unsigned long Des_Addr //start address of Destination,unsigned short Des_W //image width of Destination (recommend = canvas image width),unsigned short XDes //coordinate Y of Destination,unsigned short YDes //coordinate Y of Destination,unsigned short X_W //Width BTE Window,unsigned short Y_H //Length BTE Window,unsigned char alpha//alpha : Alpha Blending effect 0 ~ 32, Destination data = (Source 0 * (1- alpha)) + (Source 1 * alpha))
