Hello,

In 2017, I designed a simple and low cost 10 MHz GPS controlled oscillator to improve its accuracy. It used a cheap GPS board, an Adafruit Si5351 to generate the RF signal and an Arduino Nano is doing almost all the work.
When I wrote my Arduino sketch, the Jason Milldrum NT7S Si5351 available library was the 2.0.1 version. Later on, new revisions were published but the 'set_correction' function was different from the older one : this function now needs two parameters instead of one. Thus my old Arduino programs (up to V.4.1 included) can't be compiled properly.
I modified my program recently so that it can be used with the new library. My new program is the GPS_Si_ V5.0.
This time base and the new updates are presented in my Web page and may be of interest to some of you:
