Good day.
I use the following code that responsible for encoder counting and send the reading to WINcc using ARDUINO mega and Ethernet shield .
The encoder counts correctly on serial monitor but no response on Wincc
Could you help in that issue?
#include <SPI.h>
#include <Ethernet.h>
#include "Mudbus.h"
Mudbus Mb;
float asd;
volatile unsigned int temp, counter = 0; //This variable will increase or decrease depending on the rotation of encoder
void setup() {
uint8_t mac[] = { 0x90, 0xA2, 0xDA, 0x00, 0x51, 0x06 };
uint8_t ip[] = { 192, 168, 1, 8 };
uint8_t gateway[] = { 192, 168, 1, 1 };
uint8_t subnet[] = { 255, 255, 255, 0 };
Ethernet.begin(mac, ip, gateway, subnet);
Serial.begin (9600);
pinMode(2, INPUT_PULLUP); // internal pullup input pin 2
pinMode(3, INPUT_PULLUP); // internalเป็น pullup input pin 3
//Setting up interrupt
//A rising pulse from encodenren activated ai0(). AttachInterrupt 0 is DigitalPin nr 2 on moust Arduino.
attachInterrupt(0, ai0, RISING);
//B rising pulse from encodenren activated ai1(). AttachInterrupt 1 is DigitalPin nr 3 on moust Arduino.
attachInterrupt(1, ai1, RISING);
}
void loop() {
// Send the value of counter
if( counter != temp ){
Serial.println (counter);
temp = counter;
asd=temp;
}
Mb.Run();
Mb.R[1] = analogRead(asd);
}
void ai0() {
// ai0 is activated if DigitalPin nr 2 is going from LOW to HIGH
// Check pin 3 to determine the direction
if(digitalRead(3)==LOW) {
counter++;
}else{
counter--;
}
}
void ai1() {
// ai0 is activated if DigitalPin nr 3 is going from LOW to HIGH
// Check with pin 2 to determine the direction
if(digitalRead(2)==LOW) {
counter--;
}else{
counter++;
}
}
