Connect ATmega and NEO AIR over I2C
Posted: Wed Jul 26, 2017 12:57 pm
Hi there
I try to connect my NEO AIR and an ATMega8 over I2C bus.
I tried different implementations for I2C slave on ATMega current I'm using the implementation based on http://www.jtronics.de/avr-projekte/lib ... slave.html which is working fine on RaspberryPI2. But when I connect the Mega to my NEO it will not be discovered.
When I do 'i2cdetect -y 0' it does not detect the slave. I tried with pull up to 3.3V and 5V and without. Nothing seems to work. (When I disconnect the ATMega other I2C devices are proper detected)
Has anybody else done something similar? Any idea what I'm doing wrong?
Cheers els
