DRagos,

by the way, would you kindly fix your shematic in your spare time and repost it on here, please?

I would like to see the correct circuit.

Thank you so much!

Cool, pal.

Keep up the good work!

I think i made a mistake in the schematics, the T1 and T2 have the collector and emitter reversed.
I’m not a big-shot in electronics either, this was just a project i made so i would start to relearn it.
I will dedicate some time to electronics again next year when i have time again for electronics, but i will try to help you out if i can.

I got it. Thanks

i am not so good at electronics, but I love to learn.

by looking at your schematic, hmm

I do not really understand one thing.

r3 and r4 are pull down resistors right?
when either button is pressed, it gives a “1″ but your 7 segment displays are common cathode type

how come the cathode pins are not connected directly to the ground?

Thanks

Ps: by the way i have started learning assembly 2 weeks ago lol It will take me long to figure out the codes you wrote

draggo,

I would like to have a look at your codes too.

How I I get to the archive here for your codes? I am new here.

I can help you out. What do you need to know ? With what exactly do you need help with ? First you will have to replace the two 7 segment display with a double one. Also you will need to change the code. There are a lot of changes to be made to the code but the principle remains the same. You have to show each digit at a time, the same as with only 2 digits.

This is the answer I have been looking for! I know little about PICs, but this will head me in the right direction.

One thing though… I would like to be able to score up to 99 to 99.
Would you be willing to help me do this?

I am a teacher in upstate NY.

Thanks!

I added the hex file to the archive. please download again.
What errors did you got when compiling ?

please could you let me knowif you have a .hex for this project i cannot get the asm file to build … thanks for your help in this great project
