charlesfhda 0:761e771590e5 2 Demonstrate 0.96 in. OLED module (128x64/SPI). Revised for use with ST Nucleo L152RE
charlesfhda 0:761e771590e5 3
charlesfhda 0:761e771590e5 4 Note: On 16 pin OLED module from Taobao, MOSI connects to module D1
charlesfhda 0:761e771590e5 5 and CLK (also called SCK) connects to module D0. Module RW and RD lines
charlesfhda 0:761e771590e5 6 are connected to GND.
