2 years ago hiya, questions about how to use adafruit products are best posted in the adafruit forums at forums.adafruit.com thats where tech support is handled - github issues are where folks can issue bug reports (e.g. something that ought to work but doesnt due to a hardware or software bug)
thanks! :)

Hello. I have a project who use multiple SSD1306 128x64 display with arduino in SPI mode. My code work in 128x32 mode but when I turn it to 128x64 (native display screen), nothing is displayed. What is the problem ?
My code :
include
include
include
define OLED_MOSI 4 //2
define OLED_CLK 3 //1
define OLED_DC 5 //4
define OLED_CS 7 //5
define OLED_RESET 6 //3
define OLED_CS2 8 //5
define SCREEN_WIDTH 128 // OLED display width, in pixels
define SCREEN_HEIGHT 32 // OLED display height, in pixels
Adafruit_SSD1306 display1(SCREEN_WIDTH,SCREEN_HEIGHT, OLED_MOSI, OLED_CLK, OLED_DC, OLED_RESET, OLED_CS); Adafruit_SSD1306 display2(SCREEN_WIDTH,SCREEN_HEIGHT, OLED_MOSI, OLED_CLK, OLED_DC, -1, OLED_CS2);
void setup() { Serial.begin (9600); display1.begin(SSD1306_SWITCHCAPVCC,0); display1.clearDisplay(); display2.begin(SSD1306_SWITCHCAPVCC,0); display2.clearDisplay(); }
void loop() {
display1.begin(SSD1306_SWITCHCAPVCC,0); display1.clearDisplay(); display1.setTextSize(2,1); display1.setTextColor(WHITE); display1.setCursor(0, 0); display1.println("SHOOT"); display1.println("ADV. SHOOT"); display1.println("TURN ACW"); display1.println("SAVE POS"); display1.display();
display2.begin(SSD1306_SWITCHCAPVCC,0); display2.clearDisplay(); display2.setTextSize(2,1); display2.setTextColor(WHITE); display2.setCursor(0, 0); display2.println("LOAD"); display2.println("SAVE"); display2.println("OVERWRITE"); display2.println("RESET"); display2.display(); }
