Storing several Bitmaps (Micro OLED Breakout)

Community Projects

Hello :slight_smile:

For my project, I’m using a Sparkfun Pro Micro (3.3V) and a Sparkfun Micro OLED Breakout.

The main task of the OLED Screen is to display several Bitmaps. To save space on the Pro Micro, I tried to store the Bitmaps in PROGMEM, however, the images get all mixed up since I tried that :? .

What did I do wrong? Is there an other option to store the Bitmaps?

#include <SPI.h>
#include <SFE_MicroOLED.h>

#define PIN_RESET 9  // Connect RST to pin 9 (req. for SPI and I2C)
#define PIN_DC    8  // Connect DC to pin 8 (required for SPI)
#define PIN_CS    10 // Connect CS to pin 10 (required for SPI)

// Declare a MicroOLED object. The parameters include:
// 1 - Reset pin: Any digital pin
// 2 - D/C pin: Any digital pin (SPI mode only)
// 3 - CS pin: Any digital pin (SPI mode only, 10 recommended)
MicroOLED oled(PIN_RESET, PIN_DC, PIN_CS); // Example SPI Declaration

const uint8_t Bitmap1 [] PROGMEM = {
