typo: Assertion error when fractional pll denominator is 0xFFFFF #6
Description
Line 216 in "adafruit_si5351.py" currently says:
assert 0 < denominator < 0xFFFFF # Prevent divide by zero.
Which is an attempt to throw an assertion when the denominator is zero, or out of bounds.
The spec sheet says that 1048575 = 0xFFFFF is the maximum denominator allowed, and is therefore valid.
A denominator greater than 1048575 = 0xFFFFF should be asserted as an error.
The line should be modified to be:
assert 0 < denominator <= 0xFFFFF # Prevent divide by zero.
I have made this change using Feather M4 Express, running CP 4.0.2, driving an Adafruit Si5351A breakout board and verified that the Si5351A works correctly as expected with denominator 0xFFFFF.
