Application Example:
Let’s assume that you want to write a program to periodically display
some random text on the screen and save it so that if power goes off, the
unit will show the last text that you displayed.
You need to first make sure the text is properly formatted (i.e. if the
length of the text is longer than one line, you need to insert CR as
required).
Then count the # of bytes in your string and set it as string #1 length.
String #2 through 10 lengths is 0. Use a wait time of 0 for "Wait till next
string" and use the above program to send out the data. Your String will
show on the screen and will reappear after power up.
Note:
Make sure the CC mode is off (both LED’s off) to make this work.
Since after completion of playback, the unit will recall the CC mode and
if CC1 or Alt were on, the OSD will disappear before you even see it!
