+* @file main.cpp
+* @brief Sample source code for MIP8 diplay. 
+* @details  
+*
+* Addtional function is Monochome display by 1bit mode of SPI transfer.
+*
+* spi-transfer to Display has 3 mode. 
+* 4bit mode is color display, this bit arrange is  R,G,B,x.   R,G,B = R,G,B subpixel bit.  a x bit is Dummy.
+* No ues(3bit mode is color display, this bit arrange is  R,G,B.   R,G,B = R,G,B subpixel bit.  No bit is Dummy.)
+* 1bit mode is monocrome display,high speed refresh mode. a only Green subpixel of bitmap data is transfered.
