i use adf4159\adf5901\adf5904 to measue distance\velocity\angle,i collect N chirp and then use the echo data to get velocity.i control adf4159's txdata pin to trigger N chirp,however,adf4159 ceaselessly output chirps.my setting is R0.31=1(ramp is enable),R3.b11-b10=00(CON_SAWTOOTH),R7.b20=1(txdata tirgger chirp)
