Version 5.0. 4bit,3bit,1bit transfermode
Dependents: MIP8f_FRDM_TransferMode_sample MIP8f_FRDM_CountUpNumber_sample2
MIP8F_SPI_Ver5.0
Ver5.0 Addtional function is checking the refresh display speed between 4bit,3bit and 1bit transfer mode
- 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. x bit is Dummy. 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.
