POV Cylinder with Arduino Due

Story Introduction This is my first Arduino project. My work was inspired by several maker projects that created Persistence of Vision Displays [2,3,4]. Persistence of vision (POV) refers to the optical illusion whereby multiple discrete images blend into a single image in the human mind and believed to be the explanation for motion perception in cinema and animated films [1]. The projects [2,3,4] implement ...

AVR VideoBlaster: How about NTSC color video on a single chip with just 2 resistors?

Story More VideoBlasting So why didn't the TVout library reach any higher resolution than 160x100? The answer is simple. They did not use any hardware onchip to push the pixels out. If you use the SPI to push the pixel you will gain an immediate 1:1 in pixelspeed The SPI push out data at the CPU clock / 2. That is the maximum speed that the chip is capable of. On a 16MHz chip, that is an impressive 8mbps. T ...

SSD1306xLED Tinusaur ATtiny85 Library for SSD1306

Story SSD1306xLED is a C library for working with the SSD1306 display driver to control dot matrix OLED/PLED 128×64 displays. It is intended to be used with the Tinusaur board but should also work with any other board based on ATtiny85 or similar microcontroller. The 128×64 OLED is controlled by a SSD1306 circuit and could be interfaced over I²C. The code could be divided in 3 pieces: Communication over I²C ...

Tiny Lisp Computer

This article describes a self-contained computer with its own display and keyboard, based on an ATmega328, that you can program in Lisp. You can use it to run programs that interface to components such as LEDs and push-buttons via the I/O pins, read the analogue inputs, and operate external devices via the I2C and SPI interfaces. It has a small monochrome OLED display that gives 8 lines of 21 characters per ...
