4d systems OLED display w/4DGL microcode “interpreter”, 461 bytes of instructions to read serial data (tied to the ftdi -> usb chip) to see if the current display needs to be changed, hardcoded sector-reading code to read images from SD card, ramping contrast to fade between images, and a win32 client app that simply sends 1 byte per mode change and keeps state in the system tray.
