Lcd

Hello everyone, I have another question.

I have this neat little serial 2x8 lcd screen. Its got this rs-232 port with a gnd, 5v, and rx pin. I think I have this lcd connected accordingly. gnd on gnd pin, 5v on 5vpin, and rx on I/O pin. I then send a " sendserial(d15, 9600, "hi") " and i get all kinds of weird symbols. Ive tried sending hexidecimal commands like " sendserial(d15, 9600, 0xFE, 0x46) " to try n turn it off according to its manual and the same symbols pop out..looks like nothing realy. So I'm sure im doing something wrong, I just dont know what yet.

theres also a serial port with gnd, 5v, rx, tx, should i be using those instead n use d16's I/o pin for the tx?

Any help would be appreciated. :)

Hello Rich, how are you?

Well, I have a feeling the LCD is now toast. I've soldered them with wires, I have even salvaged some 0 ohm resistors and soldered those on. Allthough the result are now definitly consistent, it only produces fully blacked out blocks on the display regardless of what i send to it so long as it is with 4800 or 9600 baud rate.

But it's okay. I've put this lcd thing asside sometime ago and I have no problem leaving it there. :P

Anyway, thanks for your replies.
