DM128064 monochrome 128x64 LCD Display

softgun simulates a DM128064 monochrome graphics Display. The simulated graphics controller Chip is a Solomon SSD1815 which is similar to the Sitronix ST7565r.

Features:

Contrast an gain settings are simulated by changing some strange gamma curves for pixel brightness.
The supply voltage from configfile has an effect on contrast.
Scan direction can be changed.
Response time simulation with a default of 125ms
Timing is not checked currently because the real chip works with 12 MHz even if only specified for 4 MHz.

The interface is a SPI slave simulation on logical signal level and consists of the following signals.

dm128064.cs1
dm128064.reset
dm128064.rs
dm128064.sclk
dm128064.sid
