Hello, I was messing around with the calc functions at the bottom of my code then I started getting this error. Help please, I cannot see what is wrong.
#include <Wire.h>
#include <LiquidCrystal_I2C.h>

long T; //Torque

int f; //frequency
int N; //mapped RPM
int valN; //rmp before mapping
int valT; // torque be4mapping

lcd.init();
lcd.backlight();
lcd.clear();
pinMode(OnOffSw, INPUT);
pinMode(DirectionSw, INPUT_PULLUP);
}
void loop() {
calcSpeed();
calcFrequency();
calcTorque();
calcPw();
if (digitalRead(OnOffSw) == HIGH) {
lcd.setCursor(0, 0);
lcd.print("Motor OFF");
delay(400);
lcd.clear();
}

lcd.clear();
