Progress Halted (Celtic III bug)
« on: February 27, 2009, 05:13:11 pm »
Well... I was experimenting with the contrast changing code.
I was just doing a simple fade to white and then back to normal.
Code: [Select]
:real(3,3,0,1
:For(X,23,0,-.1
:real(5,0,X
:End
:real(5,0,23

Well, the first time I get something like what I get from WabbitEmu. (except that it actually fades out)


After a few more tries... everything now displays upside-down.
Typing normally, menus, everything is upside-down.

Turning it on and off doesn't work and neither does uninstalling Celtic III... so I'm going to have to reset after getting all the stuff off of my calc.

So, just a warning... real(5) is screwy. At least in a for loop. I haven't tried it in any other way.

hmm, isn't there a CelticIII alternate to changing contrast?

after looking, i guess not.

are you positive you didn't accidentally do real(4), scrollscreen?

Yep. Positive.
Even if I did, (which I didn't) how would that make the entire screen upside-down?
(EDIT: Of course, now that I think about it... the contrast thing shouldn't have made it upside-down either...)

It looks like he's outputting values to the LCD port outside of the range used for contrast. This has potential to cause the blue screen...

Edit: It looks like you're outputting decimals, and Celtic probably expects integers.

If you want to return the screen to normal, run this program:
Code: [Select]

Ouch that is very bad. Blue screen of death. Can screw your lcd.
You have to contact Iambian... Even it is only made with bad inputs, is better to do put checks and avoid bad instructions to lcd.

That makes sense now that you mention it.
I, for some reason, assumed it'd round. No clue why. >_<

Thanks, mate.
Although, the fix you suggested did not work.
Well, it did for the screen placement, but not the upside-down problem.

haha. yeah, the contrast command excepts positive integers only!
Passing negative values or decimal values can do some crazy things.

Sort of like when I hit a pot hole in the road that threw off the steering, then another one got it back :D  It works!

Haven't done the reset, (distracted) but I had tried to redo it...
It won't. In fact, it works fine all of a sudden... it's just upside-down.
So... yeah...
Definitely going to have to see whether or not there's any permanent damage.

upside down isn't permanent damage?

I reset the whole thing... (not just the RAM) and it's still upside-down.
So... yeah... I have no idea what I'm going to do now.
It's beyond a major inconvenience.

I guess I can still program at home and test on WabbitEmu... but meh, it'll slow down things even more so.
