adafruit_ssd1351_library's Introduction

Adafruit_mfGFX_Library
======================

Multifont version of Adafruit_GFX library with Adafruit SSD1351 Display drivers and demo.

This library supports any compatible Adafruit_GFX display driver.  The free TheDotFactory Windows program is recommended for created data compatible with the Adafruit_mfGFX library.

Please see the README.pdf files for instructions on creating and adding new fonts.  The base library comes with 4 fonts and a "test" font so new candidate font data can easily be added and tested before being permanently added to the library.

BE AWARE that though font data does not take up Spark RAM, they do however take up flash space so having too many fonts may prove problematic.

** UPDATED with font compilation option, June 2014


This is a library for the 1.27" & 1.5" 16-bit Color OLED with SSD1351 driver chip

These displays use SPI to communicate, 4 or 5 pins are required to  
interface

adafruit_ssd1351_library's Issues

No issue, only a suggestion to use fast IO in very frequently used fn()s

Since these are the most commonly used functions in the lib fast IO might be advantageous.

void Adafruit_SSD1351::writeCommand(uint8_t c) {
    digitalWrite(_rs, LOW);
    digitalWrite(_cs, LOW);

    //Serial.print("C ");
    spiwrite(c);

    digitalWrite(_cs, HIGH);
}

void Adafruit_SSD1351::writeData(uint8_t c) {
    digitalWrite(_rs, HIGH);
    digitalWrite(_cs, LOW);

//    Serial.print("D ");
    spiwrite(c);

    digitalWrite(_cs, HIGH);
}
