Reading both encoders and switches at the same time.

Projects Programming
1

Hi all
Im new to this so be patient. Im making a project that requires an encoder adjustment then a button press to change OLED screens.
I have the OLED showing the values from the encoder but it looks like the code just sits there paused waiting for an encoder change so its not scanning the switches.
How can I get it to do both ....please make it simple guys.

Please post some code so we can help you :slight_smile:

#include <SPI.h>
#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
#include <Encoder.h>
Encoder myEnc(2, 3);
#define OLED_RESET 4

Adafruit_SSD1306 display(OLED_RESET);

// encoder variables
int newPos;
int oldPos;

#if (SSD1306_LCDHEIGHT != 32)
#error("Height incorrect, please fix Adafruit_SSD1306.h!");
#endif

void setup() {
Serial.begin(9600);
display.begin(SSD1306_SWITCHCAPVCC, 0x3C); // initialize with the I2C addr 0x3C (for the 128x32)
display.display();
delay(800);
display.clearDisplay();

// this sets up the screen and just displays rubish to check its working
display.setTextSize(1);
display.setTextColor(WHITE);
display.setCursor(0,5);
display.setTextSize(2);
display.setTextColor(WHITE);
display.print("0x");
display.println(0xDEADBEEF, HEX);
display.display();
delay(2000);
display.clearDisplay();

}

void loop()

// I need to be able to read any of the 3 buttons
// sw1,sw2,sw3 then act on the result accordingly
// hope this helps ...my first real project.

// Im using an UNO

{
// read encoder
long newPos = myEnc.read();
if (newPos != oldPos) {
oldPos = newPos;
// disply data on OLED screen
display.setTextSize(1);
display.setTextColor(WHITE);
display.setCursor(0,0);
// display the fuction of the 3 buttons
display.println("RST DIR GO");
display.setTextSize(2);
display.setTextColor(WHITE);
display.setCursor(20,10);
// Display the value of the encoder
display.println(newPos);
display.display();
delay(1);
display.clearDisplay();

}
