WebbThen enable the timer on the line before the block and disable it on the line after the block. The TCNT will now hold the number of cycles the block took, less the fixed cycles for the enable and disable code. Note that the TNCT will overflow after 65535 clock cycles on a 16 bit timer. You can use the overflow flag to double run time. Webb这个函数不要用在计算很长的时间 (因为 ticks_*() 函数会回绕，通常周期不是很长)。通常用法是在带超时的轮询事件中调用: # Wait for GPIO pin to be asserted, but at most 500us start = time.ticks_us() while pin.value() == 0: if time.ticks_diff(start, time.ticks_us()) > 500: … http://www.doctormonk.com/2012/01/arduino-timer-library.html masonry pier repairs

WebbI have a motor, rated at 2600 Rpm and an encoder 256 counts per revolution. I count the ticks of the encoder with input interrupt and I also use a timer interrupt to take the difference between counts in 1 ms. If I spin at 2600 RPM, I would read 2600*256 = 665600 counts in 1 minute (60 seconds). So, in 1 second I read 665600/60 counts, which is ... Webb27 sep. 2013 · AVR Timer Calculator.
