632 - Atmel micro interface ?

[Merlin]

Okay, like I'd mentioned earlier my LCD is only displaying partial characters (say 2/3 of the entire character). so i just want to make sure my connections are okay.

i'm interfacing a 632 to an Atmel micro (163, now the Atmel 16). i'm using the UART without an RS-232 chip so i've soldered the connections that set the LCD up for inverted 0-5V signal. Anything else required for this?

i think the connections are fine, because the boot screen is also screwed up. but just wanted to run it past everyone. Thanks

If you can see "most" of the data then the connection is probably OK. Support will contact you about replacing the display that only shows partial characters.

Did you check a few jumpers?

Make sure you have setup the jumpers on the 632 properly, you want the 0-5 volt logic selection and you want to invert the data because your not using a level shifter which would do that.

Good luck

i got a new lcd and it set it up and it worked just fine. so somehow, my first 632 went bad.
