If your project requires simultaneous data flows, see Paul Stoffregen's AltSoftSerial library. On Arduino or Genuino 101 RX doesn't work on Pin 13.On Arduino or Genuino 101 the current maximum RX speed is 57600bps.Not all pins on the Leonardo and Micro support change interrupts, so only the following can be used for RX: 8, 9, 10, 11, 14 (MISO), 15 (SCK), 16 (MOSI).

If using multiple software serial ports, only one can receive data at a time.

The library has the following known limitations: The version of SoftwareSerial included in 1.0 and later is based on the NewSoftSerial library by Mikal Hart. A parameter enables inverted signaling for devices which require that protocol. It is possible to have multiple software serial ports with speeds up to 115200 bps. The SoftwareSerial library has been developed to allow serial communication on other digital pins of the Arduino, using software to replicate the functionality (hence the name " SoftwareSerial"). This hardware allows the Atmega chip to receive serial communication even while working on other tasks, as long as there room in the 64 byte serial buffer. The native serial support happens via a piece of hardware (built into the chip) called a UART. The Arduino hardware has built-in support for serial communication on pins 0 and 1 (which also goes to the computer via the USB connection). If you see compilation errors check that you have installed proper library required for OLED Display.Reference Language | Libraries | Comparison | Changes Serial.println("Initializing OLED Display") ĭtTextAlignment(TEXT_ALIGN_LEFT) ĭisplay.drawString(0, 10, "Hello world") ĭisplay.drawString(0, 26, "Hello world") Īfter uploading display will show Hello World and some square and circles.

The transfer material, emission layer material and choice of electrode are the key factors that determine the quality of OLED components. The holes and electrons combine inside the EML to form excitons, after which electro luminescence occurs. By applying the appropriate electric voltage, holes and electrons are injected into the EML from the anode and the cathode, respectively. The organic materials compose a multi-layered thin film, which includes the Hole Transporting Layer (HTL), Emission Layer (EML) and the Electron Transporting Layer (ETL). OLEDs basic structure consists of organic materials positioned between the cathode and the anode, which is composed of electric conductive transparent Indium Tin Oxide (ITO). OLED possesses high application potential for virtually all types of displays and is regarded as the ultimate technology for the next generation of flat-panel displays.

In contrast to LCD technology, OLED does not require a backlight. OLED (Organic Light-Emitting Diode) is a self light-emitting technology composed of a thin, multi-layered organic film placed between an anode and cathode. This is a 0.96 inch blue/white OLED display module can be interfaced with any microcontroller using SPI/IIC protocols.
