(FTDI cable NOT included, 7th picture shows cable orientation for programming, 8th picture shows pinouts that are under the installed connector) I make these little smart displays for use in my BattSix products and they are such fun to work with I am offering them on ebay. This one includes a 150mah battery and a Mini USB charger board & cable, you'll need to add a switch to turn the computer ON/OFF. Shrink your Arduino project to the size of a silver dollar! /* It consists of a Pro Mini with a 128 X 64 yellow/blue OLED display, I program using an FTDI cable...sparkfunDOTcom/products/9718 This little demo is based on Addafruit's clock demo using the internal Arduino timer. It shows the correct pin assignments for the display. */ // you will need SPI, Wire, Adafruit_GFX, Adafruit_SSD1306 and RTClib in your library, // follow the instructions in Adafruit_SSD1306.h to set the display height to 64. #include <SPI.h> #include <Wire.h> #include <Adafruit_GFX.h> #include <Adafruit_SSD1306.h> #include "RTClib.h" RTC_Millis rtc; // software SPI // use these settings for the OLED_Pro smart display... // remove any other code that is controlling these pins. #define OLED_DC 6 #define OLED_RESET 5 #define OLED_MOSI 4 #define OLED_CLK 3 #define OLED_CS 7 Adafruit_SSD1306 display(OLED_MOSI, OLED_CLK, OLED_DC, OLED_RESET, OLED_CS); #if (SSD1306_LCDHEIGHT != 64) #error("Height incorrect, please fix Adafruit_SSD1306.h!"); #endif void setup() { // VCC for display pinMode(2, OUTPUT); digitalWrite(2, HIGH); // following line sets the RTC to the date & time this sketch was compiled rtc.begin(DateTime(F(__DATE__), F(__TIME__))); /* This line sets the RTC with an explicit date & time, you could add a couple pushbottons and additional code to manually set date and time. for example to set January 21, 2014 at 3am you would call: rtc.adjust(DateTime(2014, 1, 21, 3, 0, 0)); */ // generate the high voltage internally display.begin(SSD1306_SWITCHCAPVCC); display.setTextColor(WHITE); } void loop() { display.clearDisplay(); DateTime now = rtc.now(); display.setTextSize(4); display.setCursor(6,16); //to display 12 hour time... if(now.hour()<10){display.print(" ");} if(now.hour()-12<10 && now.hour()-12>0){display.print(" ");} if(now.hour()>12){display.print(now.hour()-12,DEC);} else{ display.print(now.hour(), DEC);} display.print(':'); // if(now.minute()<10){display.print("0");} display.print(now.minute(), DEC); display.setTextSize(2); display.setCursor(53,49); // if(now.second()<10){display.print("0");} display.print(now.second(), DEC); display.setTextSize(2); display.setCursor(6,0); display.print(now.month(), DEC); display.print('/'); display.print(now.day(), DEC); display.print('/'); display.print(now.year(), DEC); display.display(); }
