SPI 25-bit LSB first

Pin 1 CLK Pin 2 MOSI (DAT) Pin 3 CS (active low)

First 25 bits = 0x000110 Second 25 bits = freq (from table below)

If you just send 0x000110 Then it switches from Mix to Diversity and vice-versa

The command/data from the goggles is first sent to the left bay, then the right bay.

It looks like the values are the RTC6715 commands to write Synthesiser Register A and B.

0x000110 in LSB order is

  • 4 bits address 0 = Register A
  • 1 bit R/W set to 1 to write to Register A
  • 20 bits 0x0008 = Synthesizer A divisor = 8

Sample Value for channel A1 (5865MHz) 0x0540B1 in LSB order is

  • 4 bits address 1 = Register B
  • 1 bit R/W set to 1 to write to register B
  • 20 bits 0x2A05 = which fits the formula in the Richwave 6715 PDF datasheet

DSLogic capture

This is a capture switching from Mix to Diversity and back again while on channel F3 Change mode

This capture is performing a band scan Band scan

Switch to Diversity

0x000110, 500us delay, 0x000110 and channel

Switch to Mix

While CS is HIGH, CLK high 100ms, CLK low 500ms, (CS LOW) 0x000110, 500us delay (CS HIGH), (CS LOW) 0x000110 and channel
