I am getting an error when trying to compile my code, and I've tried to add/remove semicolons from the end of the variables. Here's my code (not yet finished):
#include <U8x8lib.h>; // Include the OLED Screen library (U8X8)
#define breakout 0; // If you have broken out the OLED Module, set this to 1
#define ledPin 3; // Define a PWM capable pin
#define analogIn 0; // Defines the potentiometer input
int analogVal 0; // Value of the potentiometer
int PWMOut 0;
int square 0; // PWM Wave
U8X8_SSD1306_128X64_NONAME_HW_I2C u8x8(/* reset=*/ U8X8_PIN_NONE); // Tell the OLED library which display you are using
void setup() {
pinMode(ledPin, OUTPUT);
pinMode(analogIn, INPUT); // Set pin modes for the LED and potentiometer
u8x8.begin // Initialize the OLED Display
Serial.begin(9600); // Start serial at 9600 baud
if(breakout = 0){
u8x8.setBusClock(100000); // Sets I2C Bus clock speed (Not needed if the module is connected to the PCB)
}
}
void loop() {
analogVal = analogRead(analogIn);
PWMOut = map(analogVal, 0, 1023, 0, 255)
analogWrite(ledPin, PWMOut)
u8x8.clear(); // Clear the display
u8x8.setFont(u8x8_font_amstrad_cpc_extended_f); // Set the font
u8x8.setCursor(0, 0); // Set cursor position
u8x8.print("Input: ");
u8x8.print(analogVal);
u8x8.setCursor(0, 33); // Set cursor to new line (uses a system similar to coordinates)
u8x8.print("PWM: ");
u8x8.print(PWMOut);
squareWave = digitalRead(ledPin);
Serial.println(squareWave);
}
