So, I've uploaded the 0.82, will install it into the car next weekend.

t looks ok, but allready have a question: how can I disable the alternating 999 MPG? I don't need it

Saidly I'm to "amator" to modify the code, but got some ideas:
-remaining KM, and alert below 80 Km (adding a beeper maybe? )
-time measure, all travel time, and all travel avg. speed
-remove the zeros!!! So display only one zero instand of 000.00
-display rmp?

Thanks!

ps:I'm stared learning Arduino

I'm working on a "Range" gauge for some time now, but it needs some work to finish. I don't mind zeros though. RPM's are displayed on a custom screen.

Interesting idea for time measurement and avg speed, so maybe someday... ;-)

Hopefully I'll publish all changes to the code I've made soon.

I have a little problem:



What the hell is that "P"?!

[AndrzejM]

I don't know TBH. It's the first time I see that mysterious "P"

Got the error (but dont know why..)
In "char bignumchars1[]" whenever theres is "255", I've got a "P" as you can see on the pic.

Have you changed the code anyhow? Or is that clean copy of 0.82m published few post earlier?

No, not yet, first I've wanted to try the official code.
It looks like the 255 = 0xFF = all black character is a "P"...

Start with changing the code in line

#define CFG_BIGFONT_TYPE 2 // 1=Original 2=Modified (adds about 20 bytes to code size)

To Big Font type 1 and see if problem still persist.
I think that's the issue of some specific characters set for your display. But can't be sure.

I've tried it with another LCD...





The code is ok, there's something with the LCD-s character set

I'm working on two Mpguino at the moment.
One is in the car (a little modified 0.82M) to set the values and calibration, almost done, I've done more than 250km and only got 100m difference on the VSS signal!!!
The fuel need another full refill, there the diff is 5-10%

The other setup is my table and I'm working on some mods.
-I've removed the first zeros
-add a temp sensor using a d18b20 one wire sensor
-add a screen saver: after time out, this screen appears
-add L/H in the L/100km page when the car is stopped, and display --- when the car is stoped and the engine is not running.

My other plan is to add RTC an display it on the screen saver screen
It's on it way from China

[AndrzejM]

What I love in MPGuino's project is that you can customize it any way you need/like/want.

I like the idea of screen saver maybe the logo of EM? ;-)

I don't need RTC because I have OEM clock
I've build in temp measurement code into my MPGuino using OEM engine's temp sensor (that one used for daschboard) because I couldn't find a good way to mount d18b20 within the coolant flow.

I need to make some more changes to my installation, because I want to build whole MPGuino into a instrument cluster, tghen check and calibrate the temp sensor and I'll be ready to publish everything here.

Volkov,

Will you post your changes to the code?
