dogm ST7565 display modules

I wrote previously that I would review a graphic LCD made by dogm, which was provided by the company so I could update my ST7565 library. These can be bought from Mouser for reasonable prices. There are a variety of different screens and various coloured stick on LED backlights, including an RGB one. Below you can see the sample GLCD on a breadboard. It is much smaller than the other ST7565 modules I have, the whole module is 55mm by 45mm and the display area is approximately 50mm by 30mm.

Updated ST7565 library

I have made a few changes to my ST7565 library, available from GitHub. Firstly the configuration is now broken out into a new file, so that st7565.h and st7565.c can be overwritten when the library updates without interfering with port settings. A quick fix is included for the dogm displays which appear to reverse the screen in a different way to the previous screen I tested. I will do a full review of the rather nice dogm module at a later date.
