Code Problem - Strings/ LCD/ internal EEPROM

[jorge]

yep, as you say “part by part” it is easy , but when you need to have to scroll with 2 buttons ever the alphabet and send one by one the user selected character to eeprom , this isn’t as easy as it seems … this is where things get “dirty”.
As for the rest, for example:

Write:
DATA $00,"Switch01",0
Reading:
For CounterA = 0 to 16
Read CounterA,value
If CounterA=0 then goto Main
LCDOUT value
Next CounterA

Works ok , but as a whole …i´ve not been able and not seen anything working …
The code for strings by Darrel is absolutely brilliant but it misses one point … all the strings are predefined ….not a single one can be user “ personalized”/edit/create (when pics´s in runtime) …this is where I am searching an answer.

Anyway thanks a lot Mister_E :-)

y....

Write:
DATA $00,"Switch01",0
Reading:
For CounterA = 0 to 16
Read CounterA,value
If CounterA=0 then goto Main
LCDOUT value
Next CounterA

Works ok , but as a whole …i´ve not been able and not seen anything working …

How could that work? it would exit the loop the first time it starts running.
CounterA=0 and then it exits FOR loop when CounterA=1.

Any missing condition there? or was it supposed to be like If Value=0 then goto Main ?

you are right but this was only a "coderip" out off context.
the main problem was the one in the main post.

What is the problem ?

String in an array ?

Username var Byte(size_of_username)

Writing to LCD ?

LCDOUT STR Username\size_of_username

Writing to EEPROM ?

For I=0 to size_of_username:Write EEProm_Adress+I,Username[I]:Next I

???

First of all thanks for your valuable hints.
:-)
I will sure try your approach
Although, i was thinking about Darrel’s approach to strings and a way of manipulate , edit/create them...
See the Darrels great post:
http://www.pbpgroup.com/modules/wfse...p?articleid=10
but it lacks user defined messages to be stored in EEPROM...like cruising the alphabet and selecting/creating letter by letter the new text....or something like that.

Thanks jorge,

But, as you've already noticed. They are two different things entirely.

I think you should stick with BigWumpus' idea for getting things in and out of the EEPROM, but the editing of the text is going to be a bit harder.

And, like Melanie said in the post that mister_e pointed out. It's going to be easier with 3 buttons.

Sorry, not much help.

Thanks a lot for every post !
One more question:
can i increment letters as I do with numbers ( using ASCII & char vars...?)
for example if had to select number i could cycle between then like
if keypress = 1 then
number = number +1 ,
….
but with letters " letter = letter +1 " would it give me "D" char if it was in the "C" before pressing the button ? using the reference ASCII number?
Or is there another and more efficient way ?!?
