Microcontroller based Graphical lcd game

[bitfogav]

Thanks for posting that Jay, I forgot my version on Proton Basic comes with a demo version of Proteus

Looks like captalex has somewhere to start now for his GLCD project

Hi,

It works fine in the test code using your Bitmap instead of the truck

There isn't anything in the code you posted there to draw the bitmap

Jay

i've included the whole array into the source file because the compiler wouldnt let me use the #include<eva.c> header.
here is a sample of my code, with the eva.c header added to my c source files.

Code: Select all

unsigned short j,k;
const unsigned short eva_bmp[1024]
 void main()
 {



 ADCON1 = 0x0F;            // Set AN pins to Digital I/O
 Glcd_Init(&PORTB, 0, 1, 2, 3, 5, 4, &PORTD);//Glcd_Init_EP4,see Autocomplete//(CONTROL PORT,cs1,cs2,(d/i)/rs),r/w,rst,en,DATAPORT)


     do {

    // Draw circles
    Glcd_Fill(0);  // Clear screen
    Glcd_Write_Text("ALEXISTHEKING",3,20,2);
    j = 4;
      delay_ms(300);
      Glcd_Fill(0);
    while (j < 25) {
      Glcd_Circle(63,25,j,2);
      j += 3;
    }
    delay_ms(40);
                  //draw an image
            Glcd_image(eva_bmp);
            delay_ms(300);


    // Draw Lines
    Glcd_Fill(0);  // Clear screen
    Glcd_Write_Text("HEISBACKRUNCOWRUN",2,10,2);                             //(text,page(0-7),x coordinate,color,0ff,on,invert)

    delay_ms(400);

  } while (1);

}

finally man!!, bitfogav this is what i have been looking for /trying to do using the mikro C glcd libraries , but i didnt know how. i hope you could help me with porting your code to mikro C using a pic18f4550 and a wg12864b ks0108 based lcd display. and also adding an additional paddle and scoring! hence(pong).

Hi captalex, Im not familiar with mikroC, but looking at your test code, aren't you missing the GLCD librarys Or Headers? and dont you have to include the header file for which microchip you are using?, also I cant test your schematics as I dont have proteus

And as for your display backlight not working, all Ive done on mine is connect it up as this, im using a 10k potentiometer going to my 5volt supply and then the other two connections connect directly to the GLCD pin 3 and 18, this is to control the contrast of the display, you also need to connect pins 19 to 5+ and pin 20 to ground to operate the backlight.

hey bitfogav, how's the pong game coming. i was hoping that i could get a sneak at your code for movibg the paddles and generating the ball . thanks.

hey bitfogav, how's the pong game coming. i was hoping that i could get a sneak at your code for moving the paddles and generating the ball . thanks.

Hey Alex, sure. ive done it using Swordfish Basic, so it might help if you download the Swordfish SE version which you can get from here http://www.sfcompiler.co.uk/swordfish/d ... index.html your probably need the modules that come with Swordfish to understand my code better?. I haven't had much time the last week to do much more with it yet.

thanks bitfogav, you used a similar approach to what i tried to do in allegro, here's my very scary code. i have yet to setup interrupts, initialize buttons(PORTA) and so on...
i'm also using this link
http://www.ritrivi.1free.ws/index.php?o ... icle&id=69

i'll use your code gracefully!

[brad]

Thanks for sharing the code bitfogav!

[captalex]

hey bitfogav,

i ported your code to mikro c
but for the ball prototype your created in swordfish with the GLCD.square function takes only 3 parameters, x1,y1 and size of the square, in mikro C the square function takes 4 parameters so i just added the x and y parameters again since it's a square.
the problem is that when i compile the code in mikro c, it gives an error on the Glcd_Init(&PORTB,0,1,2,3,5,4,&PORTD); routine, which is a first, as the other times i have used it in other programs it worked just fine.

this is the ported code by the way

Im not sure if that ported code will work or not with mikroC? the GLCD functions in swordfish are more than likely different to that in the GLCD functions in miKroC. When I call the GLCD.Square function in swordfish I know that inside the swordfish square function it also calls the Rectangle function and thats how it draws a Square on the GLCD using swordfish:

this is the function(subroutine) for drawing a square using the swordfish module (or Class known in C language)

Public Sub Square(pX, pY, pSize As TXY)
#if GLCD_ASPECT_RATIO <> 100
Rectangle(pX, pY, pX + pSize, pY + pSize * AspectRatio / 100)
#else
Rectangle(pX, pY, pX + pSize, pY + pSize)
#endif
End Sub

You say when compiling the code in mikroC you get an error? What if you compile the code with changing the GLCD_Init after you have declared your PORT settings? not sure if that will make any difference but worth a try?!.

Code: Select all

ADCON1 = 0x0F;                // set MCU pins as digital and Set AN pins to Digital I/O
TRISA = 0xFF;                  // set PORTA bits 1-5 Inputs (buttons) ,TRISA = 0xFF; // RA0 input
TRISC = 0;                     // PORTC outputs, for led indicator to show game is on
PORTC.F2 = 0;                 // Turn OFF LED indicator  on port RC2

Glcd_Init(&PORTB,0,1,2,3,5,4,&PORTD);  // (CONTROL PORT,cs1,cs2,[(d/i)/rs],r/w,rst,en,DATAPORT)
Glcd_Fill(0);                  // clear display before we start main prog

As for using Int instead of Bytes and Words then that should be ok, When I programme I try to use the smallest data type as possible to reduce programme memory.

I didnt know that mikroC doesn't support BOOL, (booleans). the way you've done it looks like it should work.

yes bitfogav, i tried moving the code, but i still get this error
" ';' expected = found"

hey bitfogav could you compilie the original code in swordfish for me using a pic18f4550 device and portA(0,2) for the button inputs.i also used a 4mhz external clock. i have also attached a screenshot of my screen.
thanks again.

[bitfogav]

Sure, ive changed what youve asked

Heres the Hex file of my compiled Pong with the changes:

Has for your error message - I can't see where the error can be sorry.

[bitfogav]

Ive had another look over your code but still can't see why your getting that error?

TRISA Identifier redefined message means that the same identifier already exists in some unit
in your project? but I cant find it in any other unit and also you've got the ; colons in the correct places.

One thing though, you need to take out these two lines from your main loop though, and put them out above your main loop so your program reads them before everything starts, I call these before the main loop to setup the variables and set the border for the display, you dont need to call these again. (well not here anyway).

init_variables(); // setup game variables
init_border(); // setup display border

thanks bitfogav,
ive learnt alot from you man ,
ive taken the init funCtions out of the loop now,

but when i burn the hex to my pic the lcd does nothing, i think the pin assignments you used for your lcd are different from mine
well this are mine pin assignments.
portD- DATA PORT(D0-D7)
PORTB.F0- cs1
PORTB.F1- cs2
PORTB.F2- RS //REGISTER SELECT(DATA/INSTRUCTION)
PORTB.F3- R/W
PORTB.F4- EN
PORTB.F5-RST

i hope this is the cause of the problem

[bitfogav]

Yes I didnt change the GLCD pins, so thats probably why.

Im off to work now so I will have another look at it later, maybe build a 18f4550 with my pong code to test it and change the pins of the GLCD.

[bitfogav]

Hi Captalex,

Ive made up a breadboard with a GLCD using a 18f4550, I have a 4mhz Ext crystal and two buttons connected up to the microchip, Ive connected up the GLCD and the rest of the circuit as you have in your project, changed my code to suit (datalines, etc) and the code runs fine Can I just point out that the 18F4550 has an Internal Oscillator 8 MHz.

Heres a picture of it working:

hey bitfogav, "may more bytes be added to your harddrive", you circuit works completely, the ball bounces off the screen as expected.
but there is one caveat, the circuit works as expected but the orientation of the screen is on the right hand side and the pixels are negative as in they are inverted. i think my lcd screen is (0,0) for the extreme left upper corner and (128,64) for the bottom right corner of the lcd. so i think that is why the game starts on the right side. anyways thank you for effort and code man really appreciate it . your code is a just in time helper. and could you like send the swordfish work project file to me so i could include "made by captalex" in the text hehe. cheers man. here's the image on my screen
