Like a lot of previous projects, i’m trying to build a weather station.
I made a prototype with several single shields (SD card + Barometric Pressure + Humidity & Temperature sensor + RTC)
Now, I gathered all of us with more intelligence. I’m using a MEGA, with a prototype shield and an Adafruit Datalogger shield.
I can run each components, but when I decided to add RTC(i2C) and SHT(i2c) sensor, it’s finish.
I configured the square wave from the DS1307 to manage the interrupt int.0 over the mega. It’s always running, but it begin impossible to read date and humidity or temperature from the i2c protocol.
The pull-up resistors are present.
If someone have the solution, it would be great…
