And this is the error-

 #error("Height incorrect, please fix this in the Adafruit_SSD1306.h!");
  ^~~~~
exit status 1

Compilation error: #error ("Height incorrect, please fix this in the Adafruit_SSD1306.h!");

What can I do to fix it

van_der_decken · February 12, 2025, 5:53am

I would have thought that was perfectly obvious from the error message. It's literally telling you what to change, and where.

Or, you could change your sketch to not use a deprecated for years now constructor, specify the display dimensions in your sketch, and remove the now unnecessary height test. Like so:

#include <Adafruit_SSD1306.h>


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

#define OLED_RESET     -1 // Reset pin # (or -1 if sharing Arduino reset pin)
#define SCREEN_ADDRESS 0x3C ///< See datasheet for Address; 0x3D for 128x64, 0x3C for 128x32
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);

malharja123 · February 13, 2025, 4:25am

#include <SPI.h>
#include <nRF24L01.h>            
#include <RF24.h>              
#include <Wire.h>
#include <Adafruit_GFX.h>         
#include <Adafruit_SSD1306.h>     
#include <EEPROM.h>


#define SCREEN_WIDTH 128 
#define SCREEN_HEIGHT 64 

#define OLED_RESET     -1 
#define SCREEN_ADDRESS 0x3C


#define OLED_RESET 8
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);
#define NUMFLAKES 5
#define XPOS 0
#define YPOS 1
#define DELTAY 2
#if (SSD1306_LCDHEIGHT != 64)
#error("Height incorrect, please fix this in the Adafruit_SSD1306.h!");
#endif

still the same error is coming
with updated code

david_2018 · February 13, 2025, 4:54am

Remove these lines, there is no need to check the value of SSD1306_LCDHEIGHT when specifying the display height and width in the constructor. Originally the constructor did not have a method of defining the height and width, that had to be set in the library header file, and the if statement was put into code to verify that setting was correct.
