My DLE55 gas engine works with cdi ignition which has a connection(3 wires like servo connection) to an external tachometer (rpm meter). How can I connect the ignition box rpm wire to RP2040 Then send rpm to my radio(Frsky X18 with TD R10 recevier or Flysky PL18 with FTR 8B recevier) cdi

In MSRC_GUI select ESC sensor, then protocol -> PWM Select Frsky Smartport or Flysky IBUS

Connect the rpm wire to GPIO5 on RP2040
