Do you use the prescribed software init sequence ? If not, then you need
it. Also make sure that you do not send data too fast. I have had garble
happen when I sent data too fast in an application where the ready bit was
not read back. The fast data combined to change the mode of the LCD
somehow.

So when I have this problem, first I slow the data down considerably, and
if that does not help, then I start troubleshooting elsewhere.

hope this helps,

Peter
