nikos,

with some changes to your code you can still save sereral hundred words of codespace.
(Less than 1200 words should be possible)

Store the "static" strings in EEPROM

Do a search for "STRINGS EEPROM" and you'll find many examples.

Reduce the number of I2CWRITE statements by writing a subroutine "I2COUT"
Stet the required parameters and call that sub.

Raiph,

Thanks.I make a subroutine which save my some more code.But I have a problem.
Have a look:



DISPLAYADDRESSBYTE = $05
;GR Γ = RAM15 MAX6953
I2CWRITE SDA0, SCL0, DISPLAYCONTROLBYTE1, DISPLAYADDRESSBYTE, [$CB,%01111111,%00000001,%00000001,%00000001,%00000 001]
I2CWRITE SDA0, SCL0, DISPLAYCONTROLBYTE2, DISPLAYADDRESSBYTE, [$CB,%01111111,%00000001,%00000001,%00000001,%00000 001]
;GR Δ = RAM16
I2CWRITE SDA0, SCL0, DISPLAYCONTROLBYTE1, DISPLAYADDRESSBYTE, [$D0,%01111100,%01000010,%01000001,%01000010,%01111 100]
I2CWRITE SDA0, SCL0, DISPLAYCONTROLBYTE2, DISPLAYADDRESSBYTE, [$D0,%01111100,%01000010,%01000001,%01000010,%01111 100]
;GR Θ = RAM17
I2CWRITE SDA0, SCL0, DISPLAYCONTROLBYTE1, DISPLAYADDRESSBYTE, [$D5,%00111110,%01001001,%01001001,%01001001,%00111 110]
I2CWRITE SDA0, SCL0, DISPLAYCONTROLBYTE2, DISPLAYADDRESSBYTE, [$D5,%00111110,%01001001,%01001001,%01001001,%00111 110]


I would like to make a subroutine like that:


DISPLAYADDRESSBYTE = $05
X = $CB,%01111111,%00000001,%00000001,%00000001,%00000 001
GOSUB I2COUT
X = $D0,%01111100,%01000010,%01000001,%01000010,%01111 100
GOSUB I2COUT
X = $D5,%00111110,%01001001,%01001001,%01001001,%00111 110
GOSUB I2COUT
....
I2COUT:
I2CWRITE SDA0, SCL0, DISPLAYCONTROLBYTE1, DISPLAYADDRESSBYTE, [X]
I2CWRITE SDA0, SCL0, DISPLAYCONTROLBYTE2, DISPLAYADDRESSBYTE, [X]
RETURN
....

Now what variable is X?Word?
That is my problem.

nikos,

the attached example is based on your inital code with IOANNIS's modifications.

All I have done was some "cut & paste" and some modding.

It is supposed to work, but not tested.
(compiles to 1246 words)

There is still plenty of room for improvement,
the example is just ment to give you an idea.
