Kenji Arai / ST7565_SPI_LCD

Extended library from C12832 Lib. by Peter Drescher, Chris Styles & Mihail Stoyanov. LCD in the market such as AQM1248A (Akizuki), AD-12864-SPI (antendo), NHD-C12832 (Newhaven), ST7565 (adafruit) and so on

Dependents:   CW_Decoder_using_FFT_on_F446 LPC1114_SPI_LCD_ST7565family_test

Fork of C12832 by Components

Original library is below link.

https://mbed.org/users/dreschpe/code/C12832_lcd/

I extended applicable LCD's not only 128 x 32 but also 128 x 48 and 128 x 64 type of SPI LCD using ST7565 controller.
I have checked AD-12864-SPI and AQM1248 LCD.
