I have been doing sketches for some time on my Mega 2560 and have moved over (trying..) to the Grand Central and have a compile issue and can't find an example of how this should be re-written.
This modified Blink sketch does compile for the Mega and does not for the Grand Central...
The parts I have added are pieces of a larger sketch that (this part) write over to another board using i2c, an output state for a tension control, where one motor is set to turn clockwise and the other, counter clockwise (and vice-versa).
Code: Select all
#include <Wire.h>
unsigned int duration;
/*
Blink
Turns an LED on for one second, then off for one second, repeatedly.
Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
the correct LED pin independent of which board is used.
If you want to know what pin the on-board LED is connected to on your Arduino
model, check the Technical Specs of your board at:

}

}
void setDurTension(uint8_t DAC, unsigned int duration) { //Tension Bool to make a pin low or high to enable or disable tension 9 and 10 are direction 11 and 12 are frequency
Wire.beginTransmission(10);
Wire.write(DAC);
const unsigned char val1 = duration & 0xFF;
const unsigned char val2 = (duration >> 8) & 0xFF;
Wire.write(val1);
Wire.write(val2);
Wire.endTransmission();
}
Any thoughts are appreciated!
