Hello guys.
I'm trying to design a receiver with R820t and AVR Atmega8 .
I want to give a frequency to the micro and the micro make the R820t lock on the given frequency.
I don't know how to control the I2C registers to make the IC lock on the given frequency.
thank you for you help...
If any of you have a BOM of this subject I'm very appreciate to take it.

Re: Design a reciever with R820t.
What component is processing the RF output?
Best to look at the RTL-SDR driver code for the I2C implementation, that it is the best documentation you'll find.

Check the airspy firmware, they actually have a driver:

You may have to do some rewrite to get it useable.
The Atmega8 is too slow to deal with the IF signal from the tuner, but the setup/configration should be doable.
