So, for the micros() function, you get a resolution of… one microsecond ? Wrong!The resolution for micros() is 4 microseconds on all 16MHz Arduino boards: Uno, Mega, Nano, etc. For example, if you read the time with micros() and get 10000, then the next value you get is 10004...
For those who use arduino before must know the function micros() returns system time in microseconds. AVR based arduinos use TIMER0 in MCU(such as ATMEGA328) to track system time. For cortex arm M0/M3/M4 processor, the most common way is to use systick to count system time. Typically ...
at a distance of a few meters and fan blades (if turning) are an obstacle. Finally buying a cheap remote (there are kits for Arduino) is not a good option: reliable covered distance is 2-3 meters but only if perfectly aligned. In other words dont make my same mistake: ir receiver...
micros () function micros()函数返回从那时开始的微秒数,Arduino板开始运行当前程序。 这个数字溢出,即大约70分钟后回到零。 在16 MHz Arduino板(例如Duemilanove和Nano)上,此功能的分辨率为4微秒(即返回的值始终为4的倍数)。在8 MHz Arduino板(例如LilyPad)上,此功能的分辨率为8微秒。
Arduino micros()函数Arduino 时间函数micros()函数返回Arduino板开始运行当前程序时的微秒数。该数字在大约70分钟后溢出,即回到零。在16 MHz Arduino板(例如Duemilanove和Nano)上,此函数的分辨率为4微秒(即返回值总是4的倍数)。在8 MHz Arduino板(例如LilyPad)上,此函数的分辨率为8微秒。
On 8 MHzArduino boards (e.g. the LilyPad), this function has a resolution of eight microseconds. Note: there are 1,000 microseconds in a millisecond and 1,000,000 microseconds in a second. 参数 无 返回 Number of microseconds since the program started (unsigned long) 例程 unsigned long ...
This timer is 8x more precise than what the built-in Arduino micros() function gives you! You can call "get_T2_micros();" to get the microsecond value of the timer, down to the nearest 0.5 microsecond value, or you can call "get_T2_count();" to get the count value on the micr...
(PWM). This holds the switching frequency constant but varies the length of time that switches are held shut to control the output voltage. The longer the switch is shut, the longer the pulse and the higher the voltage that is developed at the load. Average power is a function of the ...

The catch is your function is now part of an ISR (Interrupt Service Routine), and must be lean / mean, and follow certain rules. More to read on:HOWTO Attach InterruptCurrently supported BoardsPortenta_H7 boards such as Portenta_H7 Rev2 ABX00042, etc., using ArduinoCore-mbed mbed_...
