Hello! I need to build a 2 channel signal generator with delay from 500 ns to 10 us between the signals. I tried the next program code for blink something (led on 13 pin) with 16 MHz frequency, but oscilloscope shows period about 25 us. What is it? Why isn't 125 ns (62.5*2)? #define ledPin 13 int …
