Help Configuring the R820T2 with Arduino???

[martinh]

Hi All,
I'm trying to use an Arduino to configure (NOT read the RF ADC data!) and it doesn't seem to be working.

- I've used a logic analyzer to capture the I2C data sent by SDR# to the chip at my walkie-talkie freq.
- I cut the lines from the SLC/SDA test points to the RTL2932
- I connected the Arduino to those lines
- I send the address 0x1A codes to the chip - I get ACKs and data returned on reads.
- I connect my scope to the output lines, key my walkie-talkie, see no IF signal like I do with a non-hacked RTL-SDR.

Thoughts on what I am doing wrong or missing?

Thanks much!!

Got it working?

Otherwise, download the airspy firmware source, it actually contains a driver for the R820T2 tuner.
