PICAXE CONTROL OF SERIAL LCD - PAUSE COMMAND
Hello. I purchased a 4 X 20 Parallax LCD serial display for a project. I have no problem sending a serout command to place some text onto the LCD. But if I place a pause command any longer than 2 seconds between additional serout commands, the LCD seems to freeze up. I've tried sending another "high" command to the LCD but to no effect.
Example: HIGH C.3
SEROUT C.3, T9600_8, ("SENSORS ON LINE")
SEROUT C.3, T9600_8, (12,22)
SEROUT C.3, T9600_8, ("HELLO DAVE")
I'm sending a "high" command on pin c.3 to get this going and it works fine. But if I increase the pause command to 3000 (3 seconds), all I get is the first line (SENSORS ON LINE) followed with a backslash (\). The screen then freezes up.
I should add that I'm sending this data over a 150' line using MAX485 chips. If I hook up the LCD directly to the Picaxe, it works fine.
Any help would be appreciated. Thanks.
