Check refresh speed by transfermode 4bit,3bit,1bit with MIP8F_SPI_Ver50

Dependencies:   MIP8F_SPI_Ver50 MIP8f_FRDM_LineBuffer_sample mbed

Dependents:   MIP8f_FRDM_Animation_sample

Introduction

this sample 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.

Usage

Copy Setting File and Image to micro SD-CARD. you can NOT use same sample color images of OTHER VERSION SAMPLE.

a) Download the following file corresponding to the target panel, and rename file identifier (.bin -> .zip), and unzip the file on micro SD Card's root directory.

LPM027M128x (400x240) :/media/uploads/JDI_Mbed_Team/400x240_ver30.bin

b) Insert micro SD-CARD to FRDM-K64F. c) Upload binary file to FRDM-K64F.and push Reset Button.
