  • After referring to this list and using the SummoningDark’s firmware version for a while which was good I found a few issues with the bitblt operation which led me to look in more detail at the driver for the screen which was essentially a wait timer. I have now found some time to re-write the firmware to the Samsung specification sheet which improves performance. I have made this firmware available here which supports both the 128x64 and 160x128 backpack in the single firmware version and solves the problems that I had.

    There are some instructions on updating the backpack and using software flow control, in addition to a Arduino library and some test programs. Maybe somebody will find it useful and save you some time.

No public wish lists :(
