I2C LCD

[Heckler]

midali,

Now I need again a your help. How i can display a variable ? (for example, x from my code )

that should be EASY!!

in your example above just replace the "hello" with X (no quotes this time)
you might need to choose how you want X to display... in the manual you should find where you can use modifiers like DEC for a decimal value or HEX for the hex value, etc.

I2CWRITE SDA, SCL,com,$40,"hello"

looks like incorrect syntax , should be like this

I2CWRITE SDA, SCL,com,[$40,"hello"]

to display x (assume pbp3)

buff var byte[16]

ARRAYWRITE buff,[dec3 x]
I2CWRITE SDA, SCL,com,[$40,str buff"]

[/CODE]

Now that I think about it you probably will need to include a "Modifer" before your variable.

Otherwise your LCD display may think the number is some sort of control character or it may be a non displayable character.


from the PBP manual...

An assortment of string-formatting modifiers is available for use within the item list
of this command. These modifiers can be used to format string output that includes
numeric values converted from variables:
Output Modifiers for Formatting Strings
Modifier Operation
{I}{S}DEC{1..10} Send decimal digits
{I}{S}BIN{1..32} Send binary digits
{I}{S}HEX{1..8} Send hexadecimal digits
REP char\count Send character c repeated n
times
STR ArrayVar{\count} Send string of n characters
See section 2.11 for details on string-formatting modifiers.

Nothing on LCD: I2CWRITE SDA, SCL,com,$40, x
In ST7036 manual I not found how I can display a decimal number.
