I make this sketch, it is working, code may be cleaner but it's working...

Available on github : https://github.com/Gis70/MySensors/tree/master/ParkingTempHum_sensor

This is my change and it is working, thank you for your help.

Thank you both for your answer.

To resume what i want to do, i want to watch when mail is arrived in my outdoor mailbox, i will do that with 2 "door sensor".

@Nca78 if i well understood that you say, interrupt was catched and wake up arduino but value1 (the status of the "door sensor") wasn't updated and so my code doesn't do anything and it fall asleep again. Is that correct ?

I know, i just have one interrupt else i'm using 2, but it was for test with one firstly.

I will try to do in another way as you say.

thanks

Hi everybody,

I spent several time trying to detect interrupt on arduino mini pro 3.3v 8mhz with Atmega328 with button but without success. I tryed to downgrade compiler in 1.6.9 but it doesn't work neither.
If i remove sleep function it's working, but i need sleep because it a battery node for the mailbox...

Each time i press the button, i can read that in the log in the serial monitor :

2369 MCO:SLP:MS=0,SMS=0,I1=0,M1=1,I2=255,M2=255
2375 MCO:SLP:TPD
2377 MCO:SLP:WUP=0
2379 MCO:SLP:MS=0,SMS=0,I1=0,M1=1,I2=255,M2=255
2383 MCO:SLP:TPD
2385 MCO:SLP:WUP=0
2387 MCO:SLP:MS=0,SMS=0,I1=0,M1=1,I2=255,M2=255
2394 MCO:SLP:TPD

But nothing else.

Could someone helping me ?

Thx,
Ghislain

I am and you ? I can give you the sketch which is working for me with library i used.

OK, i've no further idea to help you. But i think your sensor is dead. DId you try older or newer library to compile your project ?

I supply it with 5v, are you sure it's a 3v3 version ?

It worked for a while and now it doesn't ? no problem of power supply ? 3v3 ?

Where did you buy your bmp180 ? you said the 3 you have make the same behavior ? something is wrong with the BMP sensor.

Too bad, can you upload a basic example sketch in the library adafruit to read pressure and temperature, just to be sure there is the same behavior.

Hi, i'm using this sketch and I had to modify it a little bit. But i'm at work and i haven't it.

You defined the altitude to 688 meters in you sketch, are you sure, you said you're at 1014mbars. If you're really at 700m you should be near 930mbars not 1014mbars.
