LED. What I want is if pin 7 is high clk The SI5351 is controlled by special SW included to enable the SI5351 to be set with 1/1000 Hz accuracy The serial input from the GPS is not needed, only the PPS pulse. hex can be used to upload ADX firmware without using Arduino ide and compiling. Jan 2, 2021 10kHz to 120MHz VFO / RF Generator with Si5351 and Arduino VFO/RF generator for use in homebrew radio equipment such as direct conversion and superheterodyne receivers or ham transmitters. This little program will run on an ESP32 or an Arduino and can be used to set the correction factor to compensate for off frequency crystals on Si5351 modules. Simple BFO with si5351 controlled by Arduino. \WIN TITIP\SSB\si5351 The Arduino source code is well annotated and contains links to all of the required "libraries". #define XT_CAL_F 17700 //Si5351 calibration factor, adjust to get exatcly 10MHz.
