Arduino Micro and OLED display

Using Arduino Displays
1

I recent purchased an OLED from eBay, which I managed to get working with an Arduino Uno. Note, odd PCB labels which are i2c but works from SPI.

http://www.ebay.co.uk/itm/0-96-SPI-128x64-BLUE-OLED-LED-LCD-Display-Module-Arduino-Pi-PIC-TESTED-/262222699604?hash=item3d0db0dc54:g:JzwAAOSwT~9WiWsv

I now want to use a micro for a mini project and cannot get the display working, i think the GPIO references are wrong but cannot understand what is going on. Currently I have the following connections

Micro 3.3 -> display VCC
Micro GND -> display Gnd
Micro PB2 (MISO) -> display SDA
Micro PB1 (SCK) -> display SCL
Micro PD6 -> display RES
Micro PB7 -> display DC

This is the code I am using, which is based off the Adafruit standard lib

#include #include #include #include

// If using software SPI (the default case):
/*
#define OLED_MOSI 9 // display sda
#define OLED_CLK 10 // display scl
#define OLED_DC 11 // - display dc
#define OLED_CS 12
#define OLED_RESET 13 // display res
Adafruit_SSD1306 display(OLED_MOSI, OLED_CLK, OLED_DC, OLED_RESET, OLED_CS);
*/

#include <SoftwareSerial.h>
SoftwareSerial ESPserial(3, 2); // RX | TX

/* Uncomment this block to use hardware SPI */

#define OLED_DC 12
#define OLED_CS 7
#define OLED_RESET 10
Adafruit_SSD1306 display(OLED_DC, OLED_RESET, OLED_CS);

#define NUMFLAKES 10
#define XPOS 0
#define YPOS 1
#define DELTAY 2

#define LOGO16_GLCD_HEIGHT 16
#define LOGO16_GLCD_WIDTH 16

String inputString = ""; // a string to hold incoming data

void setup() {
Serial.begin(9600);
delay(1000);
Serial.println("Script started");

// by default, we'll generate the high voltage from the 3.3v line internally! (neat!)
display.begin(SSD1306_SWITCHCAPVCC);
// init done

Serial.println("Display cleared");
display.clearDisplay();

}

void loop()
{

display.clearDisplay();

inputString = "Test Test Test";
display.setTextSize(1.5);
display.setTextColor(WHITE);
display.setCursor(30,10);
display.println(inputString);

display.drawLine(0, 0, 0, 31, WHITE);
display.drawLine(0, 0, 127,0, WHITE);
display.drawLine(127, 0, 127, 31, WHITE);
display.drawLine(0, 31, 127, 31, WHITE);

display.display();
delay(200);

Serial.println("Loop finished");
}

Could any one help if there is a problem or am I doing something silly

After writing the post, I saw the pin definition was wrong the code should have been

/* Uncomment this block to use hardware SPI */
// Display SCL -> UNO 13 Micro SCK
// Display SDA -> UNO 11 Micro MOSI

#define OLED_DC 10 // Arduino micro PB6
#define OLED_CS 7 // Not sued
#define OLED_RESET 11 // Arduinio micro PB7
Adafruit_SSD1306 display(OLED_DC, OLED_RESET, OLED_CS);
