I am completely new to the atsha204. I am having difficulty understanding several things.
At first I am using a ATmega328PB to interface the two wire I2C bus. At first I want to use the atsha204 only to get random numbers and store values in EEPROM. So I do the wakup sequence (200µS SDA low and then wait 7ms, times are longer just to make sure). Then I scan the bus on all 128 addresses. But I do not get any ACK on any address. What am I missing?
Is there a library specific for the AVR in C thats easy to use? I find it hard to understand how this device is interfaced.
Glad for any help
