Getting wierd characters instead of normal digits


New member
Hello. I have the 634 LCD running crystalcontrol software. Instead of getting words and numbers, I get all these wierd sybmols and stuff. This worked fine awhile back, then I just decided to install it again yesterday and it won't work for me anymore. I am running windows xp. I didn't see any drivers the LCD that I have

BTW the Crystalfontz info appears during boot up normal.
Looking for additional LCD resources? Check out our LCD blog for the latest developments in LCD technology.

Sounds like it's communicating at the wrong baud rate. If you're using XP, go in and change the speed set from the OS for the serial port. Also make sure that both the DIP switches on the back of the display are in the "ON" position, which will set the baud rate on the module to 19.2k
