"Serout" Command help

jdolecki

My current program uses this line.

SEROUT 15,n9600, [noparse][[/noparse] "Pistol:" ] To display on my LCD.

I want to display a message stored in eeprom, with the "Data" command.


Like this.

msg1· DATA· "Pistol",0
msg2· DATA· "Assault",0
Msg3· DATA· "Sniper",0

So the SEROUT command would look to the eeprom to get the current message.

SEROUT· 15,n9600, [noparse][[/noparse] msg1]

I hope I explained it clearly.
Thanks

There is no way to directly display text from the EEPROM. You would need to read a byte from the EEPROM using a READ statement, then output it with a SEROUT and do this in a loop like this:

address var word
outByte var byte

address = msg1  ' This sets the variable to the EEPROM address of the first message
gosub displayIt

; some where else in the program is:

displayIt:
   read address,outByte  ' Get the byte from the string
   address = address + 1  ' Increment the address
   if outByte = 0 then return  ' Exit at the zero byte
   serout 15,n9600,[noparse][[/noparse]outByte]  ' Output the byte
   goto displayIt  ' Go back for another byte

Dr Evil,

This is duplicate thread as you already had one asking about displaying data on your LCD. You should follow up in your original thread in the future rather than starting a new one on the same topic.
