Maybe
(based on the "duck" code, it's possible to use more than 8 custom chars.)
But my plan is the time and the temp as a screen saver.

I want to display the interior temp, not the engine

Sure, as soon as I'm ready, I'll post the code here!

Hello all. My name is Alvin, im from Indonesia.

I just finish putting the my own MPGuino in my 96 Civic (D16Y8 i guess).
Currently I'm putting the +12V line after the ignition. Is it make the MPGuino doesn't save the last value for BIG Curr KM/L ?
I'm quiet curious if i put the +12V line directly to the battery. How did the MPGuino turn it self to off? I'm testing the MPGuino with a 12V power supply. After 7 minutes (420sec / 420000000 uSec), it just turn off the LED but not the display.

Last, im very interested to have some temperature reading in the menu. Can some one help me?

I have the code. It's really simple and just using 2x LM35 and the 1 & 2 analog pin.

#include <LiquidCrystal.h>

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

const int inPin = 1;
const int potPin = 2;

byte degree[8] = {
0b01110,
0b01010,
0b01110,
0b00000,
0b00000,
0b00000,
0b00000,
0b00000
};

void setup()
{
lcd.createChar(1, degree);
lcd.begin(16, 2);
}
void loop()
{
int value = analogRead(inPin);
int hasil = analogRead(potPin);
lcd.setCursor(0, 1);
float millivolts = (value / 1024.0) * 5000;
float millivolt = (hasil / 1024.0) * 5000;
float celsius = millivolts / 10;
float celcius = millivolt / 10;
lcd.clear();
lcd.setCursor(0,0);
lcd.print("Intake ");
lcd.print(celsius);
lcd.write(1);
lcd.print("C");
lcd.setCursor(0,1);
lcd.print("Eng.Bay ");
lcd.print(celcius);
lcd.write(1);
lcd.print("C");
delay(500);
}

Can anyone help me to put this code into the MPGuino 0.81 ?
I'm still confuse with the menu thing in the code.


regards

Alvin

MPGuino works constantly that's why it's connected to constant 12V.

And if you want to have another position in menu with temp reading you just need to create another menu entry and then add proper code for that entry.

Okay. Thanks. Still figure it out for the menu.

By the way, can i use the 16x2 LCD without I2C interface for the LCD? I mean, can i just upload the 0.82 to my MPGuino? Mine using the Freeduino schematic (without I2C interface). Cause i saw you use the 0.82 version. But, i'm still unsure for the LCD you use. I'm using 0.81, everytime i'm starting the car, it always start with a zero. It doesnt save the last trip value to the EEPROM.

Tomorrow will be a holiday in here. I'm planning to put the +12V directly to the battery. After that, i want to move the LCD and the switch to the dashboard. Then, it will the time to calibrate the injector. The VSS is running well (with the 5100 for honda civic 96), although at the >100 KM/h, MPGuino showing 3-4 KM slower than my speedometer.

Thanks

I had a similar issue with data not saved to EEPROM. But the problem disappeared one day on it's own. Can't say why.
Anyway i'm using Arduino Uno board with parallel LCD, without I2C interface.
I'll upload new code to my MPGuino and make some changes to it soon, because of some customizations. I'll share the code as soon as I'll test it.

That would be great! I've been trying to put the 0.82 with Arduino IDE 1.0.4, but it tells me that i don't have the wire library or something

Anyway, my MPGuino is connected directly to the battery. After 8 hours of idling, the LM 7805 is quite hot (like 35-43 deg C). Is it normal? I'm using heatsink for the LM. I'm measuring the heatsink temp.

Thanks

[AndrzejM]

Yes it can get hot, but even 50 degrees is not a problem.

If you have problem with IDE104 try to use the code changed by stargazerf3a

You'll find it here MPGuino metric v0.82 IDE 103

I didn't saw that
Thanks for the info

Now I'm trying the 0.82 now cause mine got a little problem.
After filling my tank, the MPGuino start to acting weird.
The character are going to ?*# something like that.
I know that i made a mistake when putting the power cause i didn't use a connector. The cable too thick, it's give me a trouble to put it in a 3-pin connector.
So, i'm going to fix it by putting a on/off switch for the -12V. So i can turn it on fast enough without damaging the EEPROM.
Hope this will be okay, cause i have to fill my tank again to calibrate it.

I was not active last couple of month and want to say hi! have a nice summer
