Re: how to change arduino/si5351 output

I don't have the code in front of me, but look for a function near the top named something like "set_freq" Note that one of the parameters to that function is the channel number.

Then search the rest of the program for where that function is called. Note that the channel number parameter is always 2. Change that to which ever channel you intend to use instead: 1, or 0.?

Then recompile and upload. Let me know how it works for you!

hello guys!

i think i am having a problem on my si5351?

i am suspecting that it may have low output, not enough drive
it has only 40mVpp on LSB and zero on USB?
checking with a DMM, clk2 (pin6) ?has low resistance to ground
while clk1 and clk0 has high resistance to ground

I have zero programming skills,
how do I edit the sketch so that the output moves from clk2 to clk1?

btw, I am using Allard's V1.20.1

thanks and 73!
