Set up Istructions for OpenHPSDR mRX PS

Post by GregMew » Fri Jun 29, 2018 2:02 pm

Hi
I have Red Pitaya talking to the above software and want to use the I2C data ports on the E2 Port of the Red Pitaya (This interface is designed by Peter DC2PD) as per pavel-demin.github.io/red-pitaya-notes/sdr-transceiver-hpsdr/

I have looked a the I2C port with a logic analyser and can see no trafic on this port at all.

Is there a setup on Open HPSDR that needs to be enabled to allow I2C traffic?

Regards

Greg

Hi Greg,

Your logic analyzer should see some I2C traffic when the SDR transceiver compatible with HPSDR is started on the Red Pitaya board. When the program running on the Red Pitaya board is started, it tries to contact several I2C addresses to discover the connected I2C devices.

If no I2C device known to the program running on the Red Pitaya board is discovered at startup, then the program doesn't send anything to the I2C bus after the initial discovery phase.

There is nothing to be enabled in PowerSDR mRX PS.

Best regards,

Pavel

Thanks Pavel

That explains why I could not see any traffic once the RP had started.

I have looked on switch on and can see some activity so all good.

Regards

Greg
