Here is an improved version of my TinyCard project, a simple text game maker to allow children to create short adventure games, interactive stories, surveys, or quizzes. It's based on a 160x128 colour TFT display and a Microchip ATtiny3224: https://t.co/GnzXUGNu0J

This final article in the series shows how to fit my hardware driver for NeoPixel (WS2812) LED displays onto the 14-pin AVR64DD14 by taking advantage of the Event System on AVR processors: https://t.co/1MFSUzKVKV

[Technoblogy @technoblogy]

This article shows how to eliminate most of the interconnections between pins on my hardware driver for NeoPixel (WS2812) LED displays by taking advantage of the Event System on AVR processors: https://t.co/ReYu7av3TR

[Technoblogy @technoblogy]

My latest project is a driver for NeoPixel (WS2812) LED displays using AVR hardware. It works by combining the SPI peripheral with a Timer/Counter using Configurable Custom Logic (CCL): https://t.co/CjULCL6tLy

The Walkie-Textie is a simple handheld device, based on an ATtiny814, that allows you to send and receive text messages using a 12-key keypad and OLED display: https://t.co/61Sz9CtdUL

[Technoblogy @technoblogy]

My latest project is a Feather-format board based on the Microchip AVR128DA32. It runs at 24MHz, has 16KB of RAM and 128KB of flash, and runs uLisp: https://t.co/MmVuSE9oXu

[Technoblogy @technoblogy]

This is a simple LED tester, based on an ATtiny85 or ATtiny202, that provides a convenient way of testing most types of through-hole or surface-mount LEDs: https://t.co/MVJJZU49mw

[Technoblogy @technoblogy]

For a more relaxed approach to life the Timescale Clock displays the time as a scrolling scale on two bi-colour dot matrix displays; see https://t.co/kwnLGwwKv7

[Technoblogy @technoblogy]

My latest project, TinyCard, is a simple text game maker to allow children to create short adventure games, interactive stories, surveys, or quizzes: https://t.co/fuSdOhCTxn

[Technoblogy @technoblogy]

My latest project is a digital clock, based on two 8x8 bi-colour LED dot matrix displays, that changes from red to green if the time is a prime number: https://t.co/ovw4i8DkSZ

[Technoblogy @technoblogy]

@ArkN_007 Definitely! Are those chips now available?

[Technoblogy @technoblogy]

This is a PCB for my scrolling text display, based on four 8x8 LED dot-matrix displays, that you can edit with a keyboard. It's based on a @MicrochipTech ATtiny85: https://t.co/0x1a5OKbF3
