Hi guys, I'm having problems with sparkfun serLCD. Sometimes (I don't now why) when I power the Arduino and the LCD I get strange symbols on the screen like "xx||xx". This happens only sometimes but it's very annoying. If i turn on and off the power a few times finally the screen shows the correct text.
At the beginning i used the pin 0 RX and I thought that was the problem so changed to the pin 3. It worked for a few days but the problems started again.
I'm using the serLCD library and everything is properly connected. It seems that there is a problem of synchronization between Arduino and the LCD but i don't know how to solve it.
