Hi everyone,

I have recently purchased a programmable LCD from omnima that comes with a Serial/USB API.

So far so good. Now I am trying to send commands to the LCD via minicom or hypertermainl, but I don't know how to send them. I believe that I have to send AT commands and then convert a command like "#(at-sign)Reboot" into ASCII code, however that did not work.

How do I use a Serial/USB API to send commands like
"#(at-sign)Reboot" (at-sign = actual at-sign and not AT)
"#(at-sign)Display Off"

to the LCD?

I hope that some of you who have experience with programmable devices could give me a starting point, because I am clearly lost here and it is not documented anywhere how to use it.

Thank you very much for you help. Any input appreciated.

Best,
Oliver

Happy Holidays
 

Hi,

I do not know anything about that device but just looking at the manual it seems you should simply key in those instructions to Hyperterminal , it does all the ascii conversion necessary.
Have you set up hyperterminal to the same default baud rate settings as the Omnima - if they are not equal you will not communicate.

While a nice looking device not sure if you will find much support for it here, did notice there is an Omnima forum online - they might be more able to help you get going.

Out of interest what have you bought it for - any particular application in mind ?
 

programmable LCD. which controller which base board. which OS does it have. Why do you need AT commands. AT commands are for modems like GSM, GPRS, Zigbee, etc
 

There is no AT commands #@ is Start of command ascii sequence
follow these steps
connect your LCD to PC
open Hyper terminal with correct buad setting and serial port/com port
after first command wait for atleast 30sec and 10sec gap between each command
#@Reboot

#@Display On

#@FloatWin Open 10 10 200 200
#@FloatWin Show
