Created page with "= Action = Send constant or variable to LCD display. <..."

New page

== (**COPIED FROM ENGLISH PAGE**) === Action =

Send constant or variable to LCD display.

<div style="padding: 0px; margin: 0px 0px 0px 4px;">

Variable or constant to display.

More variables can be displayed separated by the ; -sign

 

LCD a ; b1 ; "constant"

 

The LCD statement behaves just like the [[PRINT]] statement. So [[SPC]]() can be used too.

The only difference with PRINT is that no CR+LF is added when you send data to the LCD.

'suited for demo : yes
'commercial addon needed : no
'-----------------------------------------------------------------------------------------

$regfile = "m8515.dat" ' specify the used micro
$crystal = 4000000 ' used crystal frequency
$baud = 19200 ' use baud rate

$sim
'REMOVE the above command for the real program !!
'$sim is used for faster simulation

'note : tested in PIN mode with 4-bit

'Config Lcdpin = Pin , Db4 = Portb.1 , Db5 = Portb.2 , Db6 = Portb.3 , Db7 = Portb.4 , E = Portb.5 , Rs = Portb.6
Config Lcdpin = Pin , Db4 = Porta.4 , Db5 = Porta.5 , Db6 = Porta.6 , Db7 = Porta.7 , E = Portc.7 , Rs = Portc.6
'These settings are for the STK200 in PIN mode
'Connect only DB4 to DB7 of the LCD to the LCD connector of the STK D4-D7
'Connect the E-line of the LCD to A15 (PORTC.7) and NOT to the E line of the LCD connector
'Connect the RS, V0, GND and =5V of the LCD to the STK LCD connector

Rem with the config lcdpin statement you can override the compiler settings

Dim A As Byte
Config Lcd = 16 * 2 'configure lcd screen

'other options are 16 * 4 and 20 * 4, 20 * 2 , 16 * 1a
'When you dont include this option 16 * 2 is assumed
'16 * 1a is intended for 16 character displays with split addresses over 2 lines

'$LCD = address will turn LCD into 8-bit databus mode
' use this with uP with external RAM and/or ROM
' because it aint need the port pins !

Cls 'clear the LCD display
Lcd "Hello world." 'display this at the top line

Wait 1
Lcd "Shift this." 'display this at the lower line
