You have to modify your custom DRC. In the DoSlave structure there are two functions that can be used to change what you need.

unsigned getRfInput(unsigned /*device*/, OD::config_value_t /*tuning_freq_MHz*/) { return 0; }
unsigned getRfOutput(unsigned /*device*/, OD::config_value_t /*tuning_freq_MHz*/) { return 0; }

We use the No-OS software to interact with the transceiver. This will update the general_input_select register appropriately.

I am trying to get the FSK DRC example working on my platform but there is so much abstraction I can't figure out how to set the output to be from TX1A on the AD9361.

I need to set the tx_rf_port_output property to 0 instead of being 1. I need the config register general_input_select to be 3 instead of 76. I have a custom DRC controller, but I have no idea how to set what I need to set in there. Any attempts seem to fail miserably.

I am using ocpirun to run my XML file. Any help or guidance would be appreciated.

Thanks,
Brian
