The nop assembly language command means "do nothing" but in fact it takes a very short period to do that nothing, hence provides a very short delay before the code continues. I Set/Clear them at regular intervals using the delay command and when I connect them to the microcontroller I read a frequency (Hz). But how can I generate 100-1000 nanosecond pulse using arduino? The lowest delay time in arduino is 1 microsecond (1000 ns) plus time taken by digitalWrite and digitalRead functions (working with ports directly still takes more that 120 ns more). Stoppe le programme pendant la durée (en microsecondes) spécifiées en paramètres. de/ and Arduino Timer Interrupts Calculator And I believe the best way to do it is by using a CTC mode with Prescaler = 1 so with 16Mhz clock the compare match register OCRnA must be equal to 15 according to the famous formula: 16MHz/(1 Funciones de tiempo en Arduino. I am a bit confused on the math to get to 1uS Sep 15, 2015 · Problems with Arduino mega 1 microsecond timer. My issue is that I don't know if this will work, because I need to calculate the amount of microseconds to delay, and I am afraid that this calculations might be taking more than the amount of microseconds I need to delay, making the whole thing pointless. (or Lo and back Hi) Usual fast way is Direct Port Manipulation (vs digitalWrite(pinX, HIGH); and digitalWrite(pinX, LOW); because the IDE adds some smarts to the writing to protect the user: Nov 8, 2024 · The Arduino programming language Reference, organized into Functions, Variable and Constant, and Structure keywords.
