Cannot set low frequency clock accurately #40

Hi, I just used the example sketch and tried to change the frequency to 10kHz.

// Set CLK1 to output 10 kHz si5351.set_freq(1000000ULL, SI5351_CLK1);

The clock I have got was in range of 641kHz. Does this code support kHz clock generation or there is some issue with the code? Please advise. Thanks! Igor

That should work, so it sounds like a regression got into the latest version of the code. Thank you for the report, I'll check it out.
