kanpapa 0:72fdbcde2fa0 10 * MARMEX_OB_oled OLED screen drawing library for mbed
kanpapa 0:72fdbcde2fa0 11 * This code has been written based on sample code and advises
kanpapa 0:72fdbcde2fa0 12 * from Ochiai-san (Marutsu-Elec). Thank you!
kanpapa 0:72fdbcde2fa0 13 *
kanpapa 0:72fdbcde2fa0 14 * SPI mode:
kanpapa 0:72fdbcde2fa0 15 * 9bit or 8bit SPI mode can be selected by disabling/enabling "#define MARMEX_OB_SPI_8BIT_MODE".
kanpapa 0:72fdbcde2fa0 16 * See source code in this (MARMEX_OB_oled.h) file.
