A few comments about the WBX boards:
|
|
They are half-duplex. I.e., transmit and receive are mutually exclusive.
|
|
There is a single LO for both the Tx and Rx sides.
|
|
The the shared control signals are hung off of the Rx side.
|
|
The shared io controls are duplexed onto the Rx side pins.
|
|
The wbx_high d'board always needs to be in 'auto_tr_mode'
