Butto count OLED

Other Hardware Displays
1

I was wondering if anyone could help me fix this code i'm new to coding and have no clue what to do. Basically i'm trying to make a button count to oled display but the code i found uses code for a SSD1306 OLED display and I have a SH1106 OLED display so i'm wondering if anyone could change the code so it works for SH1106.

Thank you

The code:

/*

#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
#include <ezButton.h>

#define SCREEN_WIDTH 128 // OLED display width, in pixels
#define SCREEN_HEIGHT 64 // OLED display height, in pixels

Adafruit_SSD1306 oled(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, -1); // create SSD1306 display object connected to I2C
ezButton button(7); // create ezButton object that attach to pin 7;
unsigned long lastCount = 0;

void setup() {
Serial.begin(9600);

// initialize OLED display with address 0x3C for 128x64
if (!oled.begin(SSD1306_SWITCHCAPVCC, 0x3C)) {
Serial.println(F("SSD1306 allocation failed"));
while (true);
}

delay(2000); // wait for initializing
oled.clearDisplay(); // clear display

oled.setTextSize(2); // text size
oled.setTextColor(WHITE); // text color
oled.setCursor(0, 10); // position to display

button.setDebounceTime(50); // set debounce time to 50 milliseconds
button.setCountMode(COUNT_FALLING);
}

void loop() {
button.loop(); // MUST call the loop() function first

unsigned long count = button.getCount();
if (lastCount != count) {
Serial.println(count); // print count to Serial Monitor
oled.clearDisplay(); // clear display
oled.println(count); // display count
oled.display(); // show on OLED
lastCount != count;
}
}

Format your code...

If you installed the SH1106 library, and choose the example, SH_1106_128x64_I2C.ino you will see it uses the same library calls as your code...

#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>

If your OLED is not working, perhaps your connections are not good. Show a picture.

Hi,
Look at this link and follow the link to the documentation.

Use the library examples to write your code.
