| 説明 | Giga quadrature decoders via interrupt.Arduino Giga R1 with 5x quadrature decoders. All inputs are read every 132us. This takes about 420.5 ns to process all 5 decoders in the interrupt routine. The max decoder speed is 4Khz on all 5 decoders (with 132 us sample time). With an encoder of 50 pulses per rev, the max motor rotation speed is (4000/50)*60 = 4800 tr/min.The computation time is measured via the output pin D22 which sets the pin high when entering the interrupt and back low when exiting the interrupt routine. The Arduino Due is used here to provide a pulse on pin D2 of the Giga every 132 us as a signal to read and process the decoders.Note: The speed is 11x higher than the Due version. |
