OLED display driver technique based on NiosⅡ

In order to display characters and graphs by using organic light-emitting diode (OLED) display, a display driver technique based on NiosⅡ was designed. Verilog HDL was written in FPGA development environment to design the interface to support OLED displayer, C program was written in NiosⅡIDE to control the generation and transmission of characters and graphs and coordinate the data transmission between FPGA and NiosⅡ processor. Finally, the designed driver was tested. It is shown that OLED display can operate properly.
