Hello,
In fact, the XN297LBW included in the HL Transmitter is a "slave" in the SPI protocol.
As I know there is no eeprom, no flash inside.
At power up it will receive from the processor "master" in the SPI protocol, parameters configuration, and after it will establish a permanent communication with the slave (TK-7.0/7.1).
I have a cheap logic analyzer, but it is too slow to catch and record the SPI flux ...
My idea is to use a Teensy 4.1 to do that, processor on this board M7 at 600MHz should be ok, but I'm not sure that the tf card can "eat" datas at this speed !
Anyway, I'm waiting my Teensy board, and I will test that.
