Certain things do go on while the delay() function is controlling the Atmega chip, however, because the delay function does not disable interrupts. Serial communication that appears at the RX pin is recorded, PWM (analogWrite) values and pin states are maintained, and interrupts will work as they should.

Testing of the device using a signal generator and an oscilloscope found the jitter of the unit to be below 3 ns and the overall delay precision 4 ns. This gives us the needed 10 ns timing which is our limit with the laser pulse width.

名称 delay() 説明 パラメータで指定した時間(ミリ秒単位)だけプログラムを一時停止する。1秒は1000ミリ秒である。 戻り値 パルスが発生していた時間(マイクロ秒)。タイムアウトが発生した時は0。 使用例 このコードは出力ピンを反転させる前に1秒待つ。

It’s possible! The Arduino delayMicroseconds() function creates the shortest delay possible from within the Arduino language. The shortest delay possible is about 2 us (microseconds). Not true – I’ve tried and the shortest is about 4.5 us. For shorter delays use

4/9/2002 · delay_x is fully source code backward compatible with So you can still request delays like: _delay_ms(.006) or use the newer ns function _delay_ns(60) It is your choice. If you want a set of accurate time-based delay functions that are guaranteed to give you

5/5/2019 · The RTOS tick period is (by default) 1ms, so vTaskDelay() will round this down to 0 ticks, and you’ll either get no delay or a full time slice (1ms) delay while another task runs. It’s not advisable to make the tick period any shorter than 1ms. The ROM function ets
