Hi, I've searched the forum and the documentation for PB3 and the displays, but I'm still confused.

Page 171 of the PB3 manual shows pin 5 of the LCD module tied to ground and page 172 shows the pin tied high. Which is correct?

I tried a simple program to clear the display and show 'READY'. The program then goes on to repeatedly flash an LED. If I comment out the Lcdout lines, the LED flashes. With the Lcdout line in place, the program hangs and the LED doesn't flash.

Can someone suggest a place for further research?

Thanks.
