Serial LCD is Killing Me! Just garbage

Hello MSLaney,

MSLKaney>>pause 1000 ' wait for the LCD to startup

serout PortB.2,4,[$FE,$01] ' clear the screen<<

I notice you are using SEROUT, instead of LCDout.... I am assuming that you are using some kind of Serial LCD....

Many LCD's have to be initialized before they will work...

LCDout does this automatically for you....
SEROUT does NOT!!!


Thus, make up your mind... either use LCDout, and let PBP do all the work for you (but this also means you must use at least 4 pins for data, and a few others for Command/Data, Clock, etc.

Or using a serial backpack type LCD... you may need to initalize manually and do the overhead yourself.



Try sending a Dec 13 to your LCD to "Initialize" it ok??? Then try writing to it...

serout PortB.2,4,[13] ' Initialize LCD

or

serout PortB.2,4,[$0D] ' Initialize LCD
