Animation demo with MIP8F_SPI_Ver60
Dependencies: mbed MIP8F_SPI_Ver60 MIP8f_FRDM_LineBuffer_sample MIP8f_FRDM_TransferMode_sample
Introduction
Animation Demo. Some Goldfish swin in water, from left to right, from bottom to top. Color and monochrome version
Only for LPM027M128x (400x240) ,JDI DIsplay.
Other information , please refer to https://os.mbed.com/teams/JapanDisplayInc/code/MIP8f_FRDM_sample/
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/goldfish_400x240.bin
b) Insert micro SD-CARD to FRDM-K64F. c) Upload binary file to FRDM-K64F.and push Reset Button.
Other information
