MARMEX-VB : "Mary Camera module" library

Dependents:   MARMEX_VB_test MARMEX_VB_Hello

MARMEX-VB (MARY-VB) camera module library for mbed. (This module may be available in Japan only.)

Kown problem / 既知の問題

The read data may have contouring. In this case, it may require reset or changing order of data reading. The order change API is available as "read_order_change()" function.
カメラから読み出したデータに擬似輪郭が発生することがあります．この問題にはシステム全体のリセットを行うか，または読み出し順の変更を行うことで対処して下さい．読み出し順の変更はAPIの"read_order_change()"関数を使うことができます．
