Hi:
I have implemented a 5.8GHz transmitter to communicate with a Drone using Teensy 3.6 via SPI connection with 2 MHz clock.
I notice a peculiar observation, the transmitter only works when I connect probes of the logic analyser (Saleae) to the SPI lines (MOSI,MISO, CLK etc)
There is suggestion to terminate the SPI lines and I read up on RC filter on high speed transmission line. Any suggestion? Do I need to have the LPF on all the lines? Any loading the Teensy?
