The Dodo is yet another homebrew 6502 single board computer. The goal is to ultimately create a portable game system out of it. The processor is the WDC 65C02, and the support chips are a 65C22 VIA, 6551 ACIA, 32k EEPROM, and a 32K SRAM. The address space design cuts the RAM in half to 16K, but the tradeoff is a very simple/flexible IO addressing scheme. The display is the 2.42″ 128×64 OLED from Adafruit running in 6800 8-bit bus mode. For software I am using the cc65 suite of development tools. I will consider this project done when it is on a PCB, mounted in a 3D printed enclosure with a gamepad built in, and I have written a game fun enough that my 4 year old digs it.
Monochrome 2.42″ 128×64 OLED Graphic Display Module Kit: If you’ve been diggin’ our monochrome OLEDs but need something bigger, this display will delight you! These displays are 2.42″ diagonal, and very readable due to the high contrast of an OLED display. This display is made of 128×64 individual white OLED pixels, each one turned on or off by the controller chip. Read more.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
