Copy SeeedGrayOLED.cpp and SeeedGrayOLED.h to ArduinoSoftwareI2C-master folder Edit SeeedGrayOLED.cpp. Click on here to download Grove-OLED-Display-1.12 library. While this library is sufficient most of the time, there are situations when it cannot be used: the I2C pins A4/A5. This is a multi-platform library that will work with several different development board types.įixed warnings regarding deprecated conversions when using print()Ĭhanged the way the screen buffer is allocatedĪdded more examples and grouped them into 128x32 and 128圆4 resolutionĪdded support for ESP8266 (only tested on Wemos/Lolin D1 Mini)Īdded support for ESP32 (only tested on Heltec WiFi Kit 32)įor a full list of changes please see the file version.txt included in the download. The standard I2C library for the Arduino is the Wire library. Some demos showcasing most of the functions are included in the download. This library will in this case fall back to a software-based, TWI-/I 2C-like protocol which will require exclusive access to the pins used. If you experience problems with pin-sharing you can move the displays SDA and SCL pins to any available pins on your development board. The interface cost 8 in kit form at 2/2010. Alternatively, they can be accessed through an interface which costs a little money, but reduces the workload inside the Arduino. MicroLans can be accessed directly by an Arduino, using the mature Arduino OneWire library. The library has not been tested in combination with the Wire library and I have no idea if they can share pins. Many 1-Wire chips can operate in both parasitic and normal power modes. If you are upgrading from an older version of the library you should read about the changes in the manual. There are some important changes from v1.xx. As of Arduino 1.0, the library inherits from the Stream functions, making it consistent with other read/write libraries. On the Arduino Mega, SDA is digital pin 20 and SCL is 21. and SCL (clock line) is on analog input pin 5. This library will default to I 2C Fast Mode (400 KHz) when using the hardware I 2C interface. Wire Library This library allows you to communicate with I2C / TWI devices. This library has been made to make it easy to use 128x32 and 128圆4 pixel OLED displays based on the SSD1306 controller chip with an Arduino, chipKit, ESP8266 or ESP32.
