V2 Screen Contrast How???

[JR-CRUZN-C5]

Ex V1 user 00 C5 Dragracer Here wondering how to change the contrast on the V2 screen. Mine has a blue background with silverish letters which are nearly impossible to see. Will never see the copy in sunlight at the dragstrip! Is there a way to change it!!

Thanks

JR

The contrast is fixed during manufacture using a resister in the FlashScan circuit board.

If the pixels on the screen were inverted, so that it was a silver/white background with blue text, would that make it more readable for you?

See images for alternate screen display.

Ironically, I was driving my car today and the daylight was making it hard to read the display. Is the above display inverting something you could build into the firmware? That would be sweet.

If it can be done Id like that as well, its hard enough to try and read a laptop in sunlight!

[Blacky]

I will make the inverted LCD display a selectable option.

Thanks Paul.

Blacky - You are incredibal!!!!!!!!!

(Blue letters on silver background will be easier to see in brightly lit areas I think!)

Amazing Paul, thanks for the hard work!! :D

[Blacky]

It was very trivial change, if only everything was so easy.

From this:

_lcdCommand(LCD_MODE_DATA,lcd_canvas.bitmap[x][r]);to this:

_lcdCommand(LCD_MODE_DATA,lcd_canvas.bitmap[x][r]^(cfgInvertLcd()?0xFF:0x00));

Wow, now he's publishing the source code :w00t:

Its a tragedy that we spend 16 hours a day, 6 days a week toiling over this code we call EFILive and no-one ever gets to see it :cool:

More source code here you'll understand it better. Its written in that little know dialect called assembler that only "real programmers " understand :master:.

Or I could just publish it like this:

0101100001000000 00000110111101001111010111111111 0010110100100110Yes, in case you're wondering I am going (have gone?) insane.

I do like your sig "And the part I really don’t understand, if you’re looking for self help, why would you read a book written by somebody else?! That’s not self help, that’s help!"
Got me thinking...
How could you counsel a person to get over their fear of counselors?

Wow, now he's publishing the source code :w00t:

I was thinking the same thing, but thought better of pushing him all the way off the edge :D

Paul - FOR YOUR EYES ONLY!!!!!!!!!!!

This is the results of your hard work on the V1 and once V2 BBL is born the front wheels will be even HIGHER!!!!!!!!!!!!!!!!!!!

It's too late, he can't be brought back, he has long since followed the "dark art" (programming)...:hihi: once you go down this path, you're possessed and consumed, a minion of the CPU, a walker of the Stack, a defiler of the Heap... you see and think in your favourite programming language :hihi:.

On my quartermile timing system, one design included replacing Atmel 2313 chips with Tiny12/13 chips ... unfortunately they don't have any RAM, so I had to switch to Assembler code on them ... I really missed hacking assembler for so long ... last time I did was back in 86 (d@mn, that's 22 years ago already ...) on my good ol' C64 ...

Makes you realize you're indeed getting older ... :(

[joecar]

Yeah we're getting older... but I found that as I get older I'm getting less stupider (not wiser)... :D

Inverting the screen on the new release works fine :) :beer:
