v17 v18 63 63 64 64 '''Setting Transmit and Receive Gains:''' For transmit gains first set `SerialTxGain(...)` mode to 1. Then using `BaseBandTxGain(...)` and `TxVGAGainControl(...)` set the transmit gain. For the receive gains the `SerialRxGain(...)` mode can be set to 0 or 1. If the mode is set to 1 the `RxLNAGainControl(...)` and `RxVGAGainControl(...)` should be used to serially set the receive gains. While when the mode is 0 the receive gains are set by a parallel bus `user_BB_gain` and `user_RF_gain` respectively. The parallel busses are inputs to the `radio_bridge` peripheral for each of the daughtercard slots. The second mode is generally used where there is a separate peripheral that selects the receive gains, for example an Automatic Gain Control algorithm. 65 66 '''Selecting Antenna Configurations:''' There are four different antenna configurations that can be used to transmit and receive data. See `radio_controller.h` for details on the different modes.
