Altimètre Arduino Pro mini

bonjour,

je viens vers vous car j'ai un souci, j'ai suivi ce tuto :
http://www.instructables.com/id/the-ultimate-altimeter-a-compact-arduino-altimeter/?allsteps

mais le problème est que je n'est pas le même capteur de pression moi j'ai un bmp180 et dans le tuto il utilise un mpl3115a2
donc j'ai du modifier le code mais sa ne fonctionne pas.

voici le code :

code: [select]

#include <sfe_bmp180.h>

#include <sevseg.h>

#include <bounce2.h>

#include <wire.h>

/*
mpl3115a2 barometric pressure sensor library example code
by: nathan seidle
sparkfun electronics
date: september 24th, 2013
license: code public domain buy me beer if use , meet someday (beerware license).

uses mpl3115a2 library display current altitude , temperature

hardware connections (breakoutboard arduino):
-vcc = 3.3v
-sda = a4 (use inline 10k resistor if board 5v)
-scl = a5 (use inline 10k resistor if board 5v)
-int pins can left unconnected demo

during testing, gps 9 satellites reported 5393ft, sensor reported 5360ft (delta of 33ft). close!
during testing, gps 8 satellites reported 1031ft, sensor reported 1021ft (delta of 10ft).

bonjour,

lorsque vous utilisez la librairie sfe_bmp180 il faut utiliser les fonctions comprises dans celle-ci. ici vous faites appel à celles de la librairie mpl3115a2 du tutoriel que vous avez suivi.
il vous faut réécrire le code en trouvant les équivalents entre les deux librairies.
