After many hours I have almost finished building the 24x24 matrix.
Heres a video of its first test, sorry for the poor quality.

24x24 led matrix
Moderators: Chuckt, Garth, bitfogav
Carrying out further tests today on the matrix, had one GREEN led not working, found the fault to a small bit of solder touching the circuits, dont think thats bad for 280 solder joints just on the Matrix board itself hehe! 
My first power board had 24 transistors BC-635 (1amp), but I found these
didnt work correctly, they would not display the colour Orange (this is done by turning green and red leds on at the same time, so I used some 2N2222 (800ma) this made the matrix dimmer, obviously as they are lower amperage output.
So I have now gone for some MPSA14 (1.2amp) transistors

Heres another test video with the new transistors.

And Heres the swordfish code - it is just something ive put together to test the matrix.

Yeah its great seeing it workingbrad wrote:Nice videos bitfogav, Isn't it great to see something happen for the first time after spending hours on a circuit
Am keen to see where this one goes - and would like to contribute code where I can also.
I was up late last night just seeing what I could with it, I will post more videos etc and make some animations but Im going away for a few days 
Ill defo need some contribution with some code when I get to possible transfer your pac-mac game to it or something?
Well thanks to you Brad and seeing your NES control pad on one of the other forum threads I have now fitted a Control Pad Port to my 24x24 microchip board, this will easily give me 8 buttons from just 3 data lines, Ive actually connected all six I/O PORTA pins to the Control Pad Port for future hardware applications and also have a 5+volt and GND supply.brad wrote:That's a great idea about pacman!
you could play it all on the one screen without the screen having to scroll.
Will certainly have to port the code over to the new screen
I have also looked into using a Playstation Control Pad, some of them have a Dual Shock control, which vibrates the control pad when it is powered up by a 9volt supply only on one of the connector lines, so imagine a racing car game where you hit another car or a wall and it vibrates your Control Pad

The NES controller works perfectly, there's never any hiccups - just a few lines of code and it's all good to go!
im almost ready to give my NES controller a go..heres a pic of the NES controller connected and my microchip board made up, oh and with my PicKit2 connected.

Heres a NEW video of the matrix
http://www.youtube.com/watch?v=VNQIBaPECC0
Thanks to Brad ive have been able to connect a NES control pad to this project quite easily and I have made a Race Car game which you could also say is based on one of Brads games. the game is still in the early stages so its pretty basic. but I am very impressed with the NES control pad!..
You might also see the fully working contol boards that Ive also made up to control the matrix in the video.
Heres the Full Code

Cool, I have yet to look at the ADC's with swordfish but I did do abit of ADC's using assembly. I have looked at EEPROM though with swordfish and i am quite amazed that this bit of code writes to eeprombrad wrote:I have just tonight started expermenting with the inbuilt ADC's within the microcontroller.
you know what has made it simple for me? SWORDFISH include files
Code: Select all
EE.Write(0,Value)
Code: Select all
eeprom.write
bsf STATUS, RP1 ; set RP1 + clear RP0 = Bank2
bcf STATUS, RP0 ; select BANK 2
movwf EEDATA ; puts contents of Working register into EEDATA register
bsf STATUS, RP0 ; selects BANK 3
bcf EECON1, EEPGD ; Stores to DATA memory (NOT Program memory)

bsf EECON1, WR ; sets bit in EECON1, WR (write) bit, STARTS a write cycle.
; The bit is cleared by hardware once write is complete.
write.done
btfsc EECON1, WR ; waits for WR bit to clear before moving on, when cleared next line skipped.
goto write.done ; goes back to write.done untill WR is cleared
bcf EECON1, WREN ; clears bit in EECON1, WREN bit (turns OFF write bit) (WREN = EEPROM Write Enable bit)
bcf STATUS, RP1 ; we now have to clear BOTH RP1 + RP0 to -
bcf STATUS, RP0 ; select BANK 0 and return to our prog.
