Tiny4kOLED for ATtiny85 and SSD1306 OLED on Wokwi Simulator

/* * Tiny4kOLED - Drivers for SSD1306 controlled dot matrix OLED/PLED 128x32 displays * * Based on ssd1306xled, re-written and extended by Stephen Denne * from 2017-04-25 at https://github.com/datacute/Tiny4kOLED * * This example shows how the scrolling features work. * When scrolling, the double buffering of screens cannot be used. * */ // Choose your I2C implementation before including Tiny4kOLED.h // The default is selected is Wire.h // To use the Wire library: //#include // To use the Adafruit's TinyWireM library: #include // To use the TinyI2C library from https://github.com/technoblogy/tiny-i2c //#include // The blue OLED screen requires a long initialization on power on. // The code to wait for it to be ready uses 20 bytes of program storage space // If you are using a white OLED, this can be reclaimed by uncommenting // the following line (before including Tiny4kOLED.h): //#define TINY4KOLED_QUICK_BEGIN #include void setup() { oled.begin(); // Two rotations are supported, // The begin() method sets the rotation to 1. //oled.setRotation(0); // Some newer devices do not contain an external current reference. // Older devices may also support using the internal curret reference, // which provides more consistent brightness across devices. // The internal current reference can be configured as either low current, or high current. // Using true as the parameter value choses the high current internal current reference, // resulting in a brighter display, and a more effective contrast setting. //oled.setInternalIref(true); // Two fonts are supplied with this library, FONT8X16 and FONT6X8 // Other fonts are available from the TinyOLED-Fonts library oled.setFont(FONT6X8); // To clear all the memory, clear both rendering frames: oled.clear(); oled.switchRenderFrame(); oled.clear(); oled.switchRenderFrame(); // The SSD1306 refers to 8 rows of pixels as a 'page' // Page 0: One line of text at the top that is not scrolling oled.setCursor(13,0); // 13 pixels to center the following text oled.print(F("Scrolling Example")); // 17 characters x 6 pixels = 102 pixels // Page 1: One lines of graphics // For this example, the scrolled area is set up below to start after 11 rows. // The top three rows of pixels in this page are not scrolling // The bottom five rows of pixels are scrolling vertically oled.setCursor(0,1); oled.fillToEOL(0x02); // Pages 2 to 6: Five lines of text that are scrolling vertically oled.setCursor(0,2); oled.print(F("Top eleven rows fixed")); oled.setCursor(0,3); oled.print(F("Fifty rows vertically")); oled.setCursor(0,4); oled.print(F("+ 5 rows horizontally")); oled.setCursor(0,5); oled.print(F("Tiny4kOLED example by")); oled.setCursor(80,6); oled.print(F("Datacute")); // Page 7: Graphics at the bottom. // This page of 8 rows of pixels is all scrolling horizontally // For this example, the vertical scroll only extends down 5 rows into this page. // The effect is that it looks like only 5 rows are scrolling horizontally. // Consequently none of the data bytes below are larger than 0x1F oled.setCursor(0,7); oled.startData(); for (uint8_t i = 0; i < 16; i++) { oled.sendData(0x02); oled.sendData(0x02); oled.sendData(0x02); oled.sendData(0x0C); oled.sendData(0x10); oled.sendData(0x10); oled.sendData(0x10); oled.sendData(0x0C); } oled.endData(); // Scroll the bottom graphics on page 7 // 'interval' is how quickly it scrolls. // 'offset' determines how far to scroll vertically for each horizontal movement // startPage = 7, interval = 1, endPage = 7, offset = 1 oled.scrollLeftOffset(7,1,7,1); // 11 rows in the top fixed (non-scrolling) area // Vertically scroll 50 rows // The remaining 3 rows are not included in the scroll, and are never visible. oled.setVerticalScrollArea(11, 50); oled.activateScroll(); oled.on(); } void loop() { // The scrolling happens automatically, and is performed by rearranging the RAM contents. }
