A tft addin for pbp3

[richard]

On which the port and pin I connects serial communication between PC and PIC

I have used rx2/tx2 (the code could be altered to use tx1/rx1)

What is the maximum number of buttons possible to make the TFT screen.

this is the limiting factor
button_flg VAR BYTE ;1 BIT PER BUTTON make it a word to have up to 16 buttons

I tried to make a four keys and the fourth button is not working. The first three are working.

button state is not defined when buttons are created easiest solution is to insert a clear command

        INCLUDE "TFT_SPI.pbpmod"        ;glcdc
        include "tft-ILI9431.bas" 
        'INCLUDE "flash_spi.pbpmod"

        include "TOUCH_TFT.PBPMOD"      ;uncomment  to use TOUCH_TFT
        INCLUDE "font7x8.bas"
    latb=255   ;  make sure tft etc are not selected ie all cs high
    TRISA=111111
    TRISB=000011    
    TRISC=010011
    TRISD=000000
    PORTD=0000000

    OSCCON = 110000         'Internal 8 Mhz Osc 
    OSCTUNE=000000        'PLL ON

   clear

    cont=500               ;half brightness
    DEFINE OSC 32
    buff var byte[32]
    t2con=5
    PR2 = 255; 
    CCPR1L = cont>>2;             ;set pwm
    ccp1con=12|((cont&3)<<4);
    SSPCON1=$20  ;$20-21-22 works 20 IS FASTEST

how I can change color of screen wallpaper from black to yellow

the screen colour has two properties fg (foreground) bg (background)
set them as you like

use fg=bg and fillrect to clear an area

how I can changes color of buttons from red to green and how to change color of outline on buttons

button_scheme var word[4] ; [background,text,border,animated (background or border) ]

defaults
button_scheme[0]= $1f
button_scheme[1]= $0
button_scheme[2]= $7ff
button_scheme[3]= $ffff

buttons can have different animations too
button_action.0[1]=1 ;flash text for this button1
button_action.0[2]=0 ;flash outline for this button2 ; default action

Why I can not write lovercase letters only capital letters work?When I write lovercase letter I got only a bad piksel on screen.
Buttons now work excellent.

[richard]

are you using the font that has lowercase chars in it ?

the first font has chr 32 to 90 post#54
the second has chr 32 to 127 post#67

Yes,wrong include I use,now it is work.

I create a counter,and when I touch the button counter increase e his value for 1.Each press increase counter for 1.

COUNTER=COUNTER+1
Is it possible to make that when i press a button and hold pressed the counter increase his value throughout the whole period when it pressed

yes good idea , I have added an auto repeat property to buttons

  button_rpt.0[3]=1             ;button3 auto rpt

Hi Richard,

I am having some issues compiling your TFT_Demo program and hope you can steer me in the right direction.
I am using Microcode Studio 5.0.0 5 and PBPX 3.0.7.4

When I first compile I get a "Syntax Error (195)". The line of code is "fillcircle 60 , 60 , 20"
I have looked through the include files and cannot find a USERCOMMAND for "fillcircle". What am I missing?

Attempting to move on, I commented out the offending fillcircle line of code and tried to compile again.
Now I get four ASM ERROR message "Address label duplication or different in second pass".
(Z001D9) (Z001DA) (Z001DB) (Z001DC)

I am very keen to get my new TFT Touchscreen operational so any advice on how to correct the above issues would be greatly appreciated.

I have attached all relevant files (main program, includes etc.) for your reference.

Cheers

hi barry


the address dup messages come from having coff file generation turned on when using dt_ints , don't know why ,wish it wouldn't
see the attached screen shot to remedy that

the syntax error i think comes from not using the latest tft-spi.pbpmod file

I have uploaded the latest just incase I stuffed up
