The steps of using this library in code are very similar tohardware interrupt. The SimpleFOCEncoderclass still provides you with all the callbacksA,BandIndexchannels but the Simple FOC library will not initialize the interrupts for you.
#define ENCODER_DO_NOT_USE_INTERRUPTS#include <Encoder.h>Encoder myEnc(7, 6);// avoid using pins with LEDs attachedvoid setup() {Serial.begin(9600);Serial.println("Basic NoInterrupts Test:");}long position = -999;void loop() {long newPos = myEnc.read();if (newPos != position) {...
我在Arduino distribution（AVRLib的一部分）的encoder.h中学会了怎样操作编码器。谢谢作者：Pascal Stang，感谢他对每一个函数友好而详细的解释。如下：Example 1 /* Read Quadrature Encoder * Connect Encoder to Pins encoder0PinA, encoder0PinB, and +5V. * * Sketch by max wolf / www.meso.net...
Whether you use the Adafruit Neopixel library, or FastLED, interrupts get disabled on many lower end CPUs like the basic Arduinos for longer than 50 µs. In turn, this stops the IR interrupt handler from running when it needs to. See also this video.One...
In thesetup()function first we initialize the encoder: // initialize encoder hardwareencoder.init(); And then instead of callingencoder.enableInterrupt()function we use thePciManagerlibrary interface to attach the interrupts. // interrupt initializationPciManager.registerListener(&listenerA);PciManager....

character date and strings. In addition to the LCD display we will scan a keypad, use hardware interrupts, all connected through a single PCA9555 module. In addition I'll reveal some code little discussed with Arduino and we will convert/manipulate code for output to the LCD display. See...
