I am reading through the firmware C codes and trying to figure out how
carry the RSSI values from auxiliary ADC in the word0 section of each
ethernet frame. I was confused by the structure of the firmware C codes.
the main() of txrx.c, there is no explicit function calls looks like
recv() for handing the ethernet frames. And I found in
some functions like send_reply(), set_reply_hdr() and
handle_control_chan_frame() which may correspond to this issue.
I also tried to modify the u2p_set_word0() function in
order to carry the RSSI value. But it seems that this only works when
starting streaming as every frame rceived on the host side shows the
I really want to know how does the frameware handle the samples and
controlling frames. Any hints?
Thanks in advance.
