-* Addtional function is Monochome display by 1bit mode of SPI transfer.
+* Ver3.0 Addtional function is font display. this demo code is tha degit is counted up like a meter panel
+* ver2.0 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.
