Masato YAMANISHI / Mbed 2 deprecated Test_SSD1306

OLED module (128x64/SPI) [aitendo VGM12864SPI-W] with Aidafruit SSD1306 library

Dependencies:   SSD1306 mbed

Dependents:   tof_main

aitendo の OLED module (128x64/SPI) [ VGM12864SPI-W] を Adafruit の SSD1306 用ライブラリで動かしてみた。グラフィックとテキスト表示が可能である。mbed 標準のGraphicDisplay/TextDisplay クラスは継承していない独自のもの。STM32 Nucleo L152RE の他、LPC1768 mbed で動作確認。
