GLCD Graphic LCD - Using Swordfish Basic

[bitfogav]

HaHaa!! i like it!!..

[odessa]

Hi Gav,

I'm using Mikrobasic for this project, if it helps heres the code...very similar to swordfish

Code: Select all

program Glcd_Test

' Glcd module connections
dim GLCD_DataPort as byte at PORTD

dim GLCD_CS1 as sbit at LATB1_bit  ' for writing to output pin always use latch (PIC18 family)
    GLCD_CS2 as sbit at LATB0_bit  ' for writing to output pin always use latch (PIC18 family)
    GLCD_RS  as sbit at LATB2_bit  ' for writing to output pin always use latch (PIC18 family)
    GLCD_RW  as sbit at LATB3_bit  ' for writing to output pin always use latch (PIC18 family)
    GLCD_EN  as sbit at LATB4_bit  ' for writing to output pin always use latch (PIC18 family)
    GLCD_RST as sbit at LATB5_bit  ' for writing to output pin always use latch (PIC18 family)

dim GLCD_CS1_Direction as sbit at TRISB1_bit
    GLCD_CS2_Direction as sbit at TRISB0_bit
    GLCD_RS_Direction  as sbit at TRISB2_bit
    GLCD_RW_Direction  as sbit at TRISB3_bit
    GLCD_EN_Direction  as sbit at TRISB4_bit
    GLCD_RST_Direction as sbit at TRISB5_bit
' End Glcd module connections

sub procedure Delay2S()                    ' 2 seconds delay sub function
  Delay_ms(2000)
end sub

main:
  CMCON  = CMCON or 0x07                   ' turn off comparators
  ADCON1 = ADCON1 or 0x0F                  ' turn off analog inputs

  Glcd_Init()                              ' Initialize Glcd
  Glcd_Fill(0x00)                          ' Clear Glcd

  while TRUE
    Glcd_Image(@cat_bmp)                            ' Draw image
    Delay2s() Delay2s()
    Glcd_fill(0x00)                                   ' Clear GLCD
    Glcd_Image(@brads_bmp)                            ' Draw image
    Delay2s() Delay2s()
    Glcd_fill(0x00)                                   ' Clear GLCD

  wend
end.

And bitmaps are handled like this

Code: Select all

module Bitmap

LOL, sorry I spelled your name 'bifo' in the code

[bitfogav]

Thanks for posting that Jay, ill have a look at it and see if I can transfer it into Swordfish code very cool thou!!

heres what ive been doing

I can see a game coming on here lol ... wheres Brad when you need a retro project game

Take a look at the Mikrobasic stuff Gav, its unreal how far advanced it is regards the amount of tools that come with it.

I have 3 packages now lol ... still at least they all have similar syntax though.

Well I woke up this morning to see you guys going absolutely crazy with these GLCD's!

I'm very impressed and if I didn't have loads of other projects on the back-burner, i'd be jumping straight into one of these.

I can certainly see a new video game system down the line somewhere with one of these displays.

How do you find the refresh rate? is it a little flickery, or does it have ghosting?

[bitfogav]

How do you find the refresh rate? is it a little flickery, or does it have ghosting?

The refresh rate is slightly poor if you are using it to drawing graphics such has the ball moving around the screen fast, the screen is flickery, especially if you constantly clear the screen after every frame.

So I come up with a different approach - instead of constantly clearing the display I just cleared the pixels of the previous position of the ball/paddle, this saves constantly updating all the data on the display, I still got a little ghosting though on the ball but I think this gives the ball a good effect as it travels around the display.

Heres a picture of the ball on the display, you can see its ghosting a little which leaves a shadded area behind the travel of the ball.

Fantastic idea bitfogav!

It is very similar to the plain ol' text LCD's if you use the LCD.CLS function, it actually produces quite a bit of a delay, however if you simply send a screen full of spaces to the display, it barely has any delay at all.

[odessa]

Gav,

Take a look at this little program. It creates the code you need for using bitmaps in Swordfish. Might be handy

Thats a great find thanks for that Jay

heres what ive been doing


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).
