calculation time fixcomma for si5351
I have a project with Arduino UNO where the execution time for the line
below is 5,78 ms. The line is part of a Wobbler, which is running with
64 steps only. I awaited 1.28 ms with BluePill. After porting to
STM32F103 see yourself.
si5351.set_freq_manual((fnow) * 100ULL, pll_freq, SI5351_CLK0); //4,5 ms
//bin von BluePill enttäuscht
My expectation was, using BluePill, 5,78 / (72/16) MHz = 1,28 ms. Result
Only 22% quicker.
I'm using only fixcomma variables.
Codes available if wanted.
