Hi there guys!
I am new to using the ardiuno due. (just got it in today) I am actually having a bit of trouble trying to compile the code. I changed the Wprogram.h to Arduino.h and the example sketch compiles fine. The problem starts when I try to compile the sketch using Scheduler.startLoop.
The error that pops up is: expected unqualified-id before '.' token. and it highlights Scheduler.startLoop
{I am trying to run two loops simultaneously where one displays the pressure sensor value from a load cell and the other displays a desired value (input from the serial monitor). }
I would really appreciate it if some one could help me out with what is it exactly that I am doing wrong! The code is as follows.
#include <Scheduler.h>
//variables for actual_value
const int digitPins1[4] = {
4, 5, 6
}; //4 common anode pins of the actual_value
const int clockPin1 = 11; //74HC595 Pin 11
const int latchPin1 = 12; //74HC595 Pin 12
const int dataPin1 = 13; //74HC595 Pin 14
const int pressurePin = A0; //pressure sensor pin
const byte digit1[10] = //actual seven segment digits in bits
{
B00111111, //0
B00000110, //1
B01011011, //2

int digitBuffer1[3] = {
0

int digitScan1 = 0;
float pressureValue;
//variables for desired_display
const int digitPins2[3] = {
