diasea 0:9adb08a2910c 10 * MARMEX_OB_oled OLED screen drawing library for mbed
diasea 0:9adb08a2910c 11 * This code has been written based on sample code and advises
diasea 0:9adb08a2910c 12 * from Ochiai-san (Marutsu-Elec). Thank you!
diasea 0:9adb08a2910c 13 *
diasea 0:9adb08a2910c 14 * SPI mode:
diasea 0:9adb08a2910c 15 * 9bit or 8bit SPI mode can be selected by disabling/enabling "#define MARMEX_OB_SPI_8BIT_MODE".
diasea 0:9adb08a2910c 16 * See source code in this (MARMEX_OB_oled.h) file.
