  • I echo Doogie’s report. It happens that some of the settings supposed to be written to eeprom (baud rate, splash screen) are lost after several power cycles.
    The baud rate problem can be solved by writing at 9600, at startup, a “change baud rate” command to the target rate. At worst, the display is already at the target rate and will misinterpret the command and display garbage, at best, it will be set to the right baud rate.
    Splash screen is more problematic, since there’s no command to systematically enable/disable it - there’s only a “toggle” command, and no way of knowing if it is in the desired state or if it reset itself.
    A problem that appeared recently is the display losing its “line width” setting, and resulting in text strangely wrapped.

No public wish lists :(
