- 通过瑞佑的液晶控制芯片可以很容易实现半透明效果、淡入淡出效果，具备该功能的型号有RA8889,RA8876,RA8876M,RA8877,RA8871M,RA8873M等等，仅需要单片机控制,代码简单易用.
代码举例:BTE_Alpha_Blending(0,2736,500,300,0,2736,1024,0,0,2736,1100,400,200,200,16);
实现效果参考视频:

通过上位机操作说明视频:

函数使用说明: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))
