Hi!
I have bought a very nice 7.8$ OLED SPI module (with embedded HV driver) on Ebay : 128X64 OLED LCD LED Display Module : UG-2864AMBAG01.
Although I have also found some code Pic OLED Code, I would like to know, if somebody tried to run it on MSP430...
Following the second link, you could download PIC18F4XK20 Demos and Lessons zipped file for schematics (see p.5.) of OLED power and code.
Controller for this OLED module is SH1101A.
