Another possibility is to use SPI as serial interface - this is much faster transfer.

Dont forget a 470nF capacitor beetween Vout and GND!

Look at Nokia3310.bas

6.3.2.$GLCD

Description:

Tells the compiler details about Graphic LCD connections.

Syntax:

$GLCD PCD8544, SDIN=PORTx.n, SCLK=PORTx.n, DC=PORTy.n, SCE=PORTy.n

Remarks:

PCD8544 or NOKIA3310 is the graphic controller chip used

SDIN, SCLK, DC, SCE Nokia display signals names.

SDIN and SCLK MUST be on the same PORT!

DC and SCE MUST be on the same PORT!

Control signals can be declared in any order!

You may also assign any valid AvrPort pin that is available for RESET Graphic module or use an appropriate RC setup for the LCD module reset like 10k PullUp resistor with 100nF capacitor to GND.

Example:

$GLCD NOKIA3310, SDIN=PORTA.0, SCLK=PORTA.1, DC=PORTA.2, SCE=PORTA.3

6.3.3.Contrast

Description:

Sets Nokia LCD module contrast.

Syntax:

Contrast=numeric expression

Remarks:

numeric expression Value from 0 to 127 to set contrast (defailt is 72).

Example:

For n=50 To 120

Contrast=n ' finding best contrast

6.3.4.FontSet

Description:

Selects soft Font.

Syntax:

FontSet NameOfFontTable

Remarks:

NameOfFontTable Table in Flash that contains individual letter definitions.

NameOfFontTable must be declared first and added into source ($Included)!

Fonts can be edited with the FastLCD utility and saved in bas format ready to include in source! Selected Font is active until another Font is selected with FontSet.

Example:

Dim F0HD As Flash Byte

Dim F1HD As Flash Byte

Dim n As Byte

Dim s As String*20

6.3.5.Glcd

Description:

Writes text on graphic LCD using previously specified soft Font.

Syntax:

GLcd(varX, varP), var

Remarks:

varX Starting X coordinate, normally between 0 and 83 varP Line to write in, between 0 and 5

var num, string, string constant or hex to write

Y coordinates are in Lines not in Pixels!

Font MUST be set (FontSet)prior to using Glcd!

If You wish to show just a few words, maybe ImgSet is better (shorter) solution (word is made as an Immage)!

If $LeadChar is defined then result will be right justified with Leading Chars as defined. Also, if Format() is defined then optional decimal point will be inserted!

6.3.6.Gwrite

Description:

Writes a byte at selected X and Line.

Syntax:

GWrite(varX, varL), var

Remarks:

varX X coordinate, normally between 0 and 83 varL Line, between 0 and 5

var to be written to desired position.

This is the graphic controllers native Write function.

Y coordinates are in Lines not in Pixels!

Example:

GWrite(17, 2), 15 ' Four pixels will be written to x=17 on the Line 2.

6.3.7.ImgSet

Description:

Displays an Image or a part of ImageArray on the graphic LCD at selected X and Line.

Syntax:

ImgSet(varX, varP), NameOfImgTable

Or, if You wat to display just a part of an ImageArray:

(Image must be saved as ImageArray, when edited using FastLCD utility!)

ImgSet(varX, varP, var), NameOfImgTable

Remarks:

varX X coordinate, normally between 0 and 83 varL Line, between 0 and 5

var which part of Image, (index in ImageArray) NameOfImgTable Table in Flash that contains the bit image.

Y coordinates are in Lines not in Pixels!

NameOfImgTable must be declared first and added into source ($Included)! Images can be edited with FastLCD image editor which can save Images in bas format. The saved image is then ready to be included in the source program!

Example:

Dim Img0 As Flash Byte

Dim Img1 As Flash Byte

$Included "C:\FastAVR\Img0.bas" ' Img0 bit image definition $Included "C:\FastAVR\Img1.bas" ' Img1 bit image definition

Second syntax:

Using ImageArray, a large letters, Icons or Sprites can be displayed, all saved in a single Image! Any part of this Image is accessable by its index, yeaa - this means animations!

Example:

Dim Sclk1616HD As Flash Byte

ImgSet(15, 2, 1), Sclk1616HD ' SandClock with index 1, second sub-Image will be displayed

$Included "C:\FastAVR\Sclk1616HD.bas" ' SandClock definition

6.3.8.Inverse

Description:

Sets NORMAL or INVERSE screen.

Syntax:

Inverse(var)

Remarks:

var 0 - normal, 1 - inverse

Only whole display can be Inversed!

6.3.9.Gcls

Description:

Clears the Graphic LCD

Syntax:

GCls

6.4.T6963C Graphic LCD support

6.4.1.$GLCD, $GCtl

Description:

Tells the compiler details about Graphic LCD connections.

Syntax:

$GLCD T6963C, Data=AVRPort, Ctrl=AVRPort, NumOfXpix, NumOfYpix, i

$GCtrl WR=4, RD=3, CE=2, CD=1, FS=1

Remarks:

T6963C is the graphic controller chip used

Data AVRPort where data bus is connected.

Ctrl AVRPort where control lines are connected.

AVRPort any valid AVRPort. Any bidirectional port can be used!

NumOfXpix how many Pixels LCD has on X

71

FastAVR Basic compiler Manual

NumOfYpix how many Pixels LCD has on Y

i 1 for single, 2 for double scan graphic LCD display module (low pix modules has single scan, larges double scan. Look datasheets for details)

WR, RD, CE, CD valid Control line names for T6963C

FS 1 for 6x8 and 0 for 8x8 fonts - tells how Bytes will be using (6 or 8 bits)

Note: Because of differences in Graphic Lcds, no provision is made for a hardware reset.

You may, however, assign any valid AvrPort pin that is available or use an appropriate RC setup for the LCD module reset. Please refer to the datasheet or manual for the specific graphic LCD module being used.

FontSelect (FS) MUST be fixed to 1 for 6x8 internal Font and 6 pix wide column or fixed to 1 for 8x8 internal Font and 8 pix wide column.

Control lines can be declared in any order!

Example:

$GLCD T6963C, Data=PORTB, Ctrl=PORTD, 128, 64, 1

$Gctrl WR=4, RD=3, CE=2, CD=1, FS=1

'WR is connected to PORTD.4, RD to PORTD.3...
