I have an OLED display that is 128x128 that I have interfaced to the DM355 SPI bus. And I would like to create a Frame buffer driver for it so that I can use Minigui, or something like it to display, Buttons, Text, Menus and Status items on the display. I already have a small library for it that I wrote for an MSP430 to do some of that but I was looking for something more sophisticated
So I have successfully created a kernel module for an SPI the DM355 SPI and used the module to initialize and display stuff on the OLED Display. I am currently looking around at framebuffer documentation but all I can seem to find is stuff about Vesa Video cards and monitors Nothing referencing such a small display. I know it won't display much, but all I want is some menus and other status items. One other potential I might want to have is to use the same minigui api's to display items on the DM355's output overlay buffer. Since there might be related data going to both the small oled screen and to the overlay. Can anyone point me in the right direction to info about the framebuffer and customizing it to allow for an SPI output interface? Tim PS. Many thanks to Joshua for your SPI Module code.
