Kako mogu stvoriti trg val signala u C za pic micros?

Bok,
to je tako lako
na primjer da kreiran 1kHz trga val koristeći CCS C compiler.
Mi calcualte T = vrijeme trajanja 1/1000Hz = 1 ms
Zatim ga podijelite sa 2 ---> 1ms / 2 = 500 us
while (1) (
output_high (PIN_A1);
delay_us (500);
output_low (PIN_A1);
delay_us (500);
)
Zdravo

Također, mnogi kontrolori imaju vremena s PWM output.Tada ćete morati program brojač na generiranje PWM ciklus s 50% carine i frekvencije 1kHz ....

Možete koristiti PWM ili vremena za stvaranje trg vala, on svibanj pravedan frekvencija tvoj potreba.
