Today I got the LCD and an external FRAM working. I usually don't care much about aesthetics, but big part of this project is the Nokia 3310 styiling, so I'm taking extra care to emulate the phone as much as possible!
I had some FRAM samples, so i opted for the FM25V10. With 1Mbit of memory, it can store 260 full screen images for the 84*48 LCD. Without huge optimizations, I can load and display an image in about 7ms.
