BS2 Link for a Matrix LCD0821

Gerry Shand

Hi All:

Has anyone had any luck with this combination? I am probably missing something simple here but the comm link I am using is 9600, 8, N, 1 using something like:

SEROUT 4, 16468, [noparse][[/noparse]$FE, "X"]
SEROUT 4, 16468, [noparse][[/noparse]$FE, "G", $01, $01]

No luck. I do get a bunch of junk on the screen though so I know the system is communicating but the above string was meant to clear the screen and put the cursor at the top left hand corner.

Any advice?

Thanks in advance.

Gerry

P.S. This is a neat little display of 2 lines x 8 characters. Works like a charm and pretty small. If I can get the thing to talk to the BS-2.

Hi Gerry , did you set the jumpers J0 through J3 for 9600 and did you solder jumper J6 for TTL , double check the schematics and compare with your wiring , try the following modification to your code

SEROUT 4, 84, [noparse][[/noparse]$FE, "X"]
SEROUT 4, 84, [noparse][[/noparse]$FE, "G", $01, $01]

I am trying to use the LCD0821 rev 2.0 and I'm having a hard time figuring it out. I am using the three pin connector and TTL but I'm getting a garbled mess on the screen. Has anyone tried this thing yet? Any help would be great. Thanks!
