634 v2.0 needs a delay of approx. 5 seconds after opening in order to
work properly. can you find the position where to insert the delay?

maybe a "Delay" parameter should be a config-option then ...

no idea ... it gets overcrowded?

the crystalfontz has a total of (if I remember correctly) 8 characters which
can be defined freely. if the graphic you are trying to display is so
"complicated", that it cannot be built with this limited amount of configure-
able characters, you get the error-message "failed to allocate a custom
character".
