![]() From now I can send data from my hardware to my Arduino in a master-slave relation, and I have no problem with that. In order to achieve that, I am using the Wire protocol (Arduino side) and I2C (custom hardware side). Everything is working perfectly independently, and I'm trying to implement a way for them (the Arduino and my hardware) to work together. If(!display.I'm doing a project that includes an Arduino Uno and custom hardware made by me. SSD1306_SWITCHCAPVCC = generate display voltage from 3.3V internally Static const unsigned char PROGMEM logo_bmp = #define NUMFLAKES 10 // Number of snowflakes in the animation example #define OLED_RESET -1 // Reset pin # (or -1 if sharing Arduino reset pin)Īdafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET) In the second half, I will go into more detail on how to display custom characters and how you can use the other functions of the LiquidCrystalI2C library. Alternatively it is possible to pass references to functions which read. The pins to be used for the serial data (SDA) and serial clock (SCL) control lines can be defined at run-time. It utilises the pinMode (), digitalWrite () and digitalRead () functions. Declaration for an SSD1306 display connected to I2C (SDA, SCL pins) SoftWire is a software I2C implementation for Arduino and other Wiring-type environments. #define SCREEN_HEIGHT 64 // OLED display height, in pixels A numCountdown timer using Arduino, LCD 16x2 i2c & 4x3 Keypad. #define SCREEN_WIDTH 128 // OLED display width, in pixels If you are having problems in adding library in Proteus 7 or 8.

Written by Limor Fried/Ladyada for Adafruit Industries, with contributions from the open source community. This example is for a 128x32 pixel display using I2C to communicate 3 pins are required to interface (two I2C and one reset).Īdafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by purchasing products from Adafruit!

This is an example for our Monochrome OLEDs based on SSD1306 drivers. I2C (Inter-Integrated Circuit) / TWI (Two-wire Interface) is a widely used serial communication to connect devices in a short distance. ![]() The following code should load: /********* ![]()
