This is an upgraded version of MBAVR-1 – a minimalist development board for tiny AVR microcontrollers like ATtiny13, ATtiny15, ATtiny25, ATtiny45 or ATtiny85. The board has been designed for a rapid prototyping of devices based on tinyAVR chips. The small-size MBAVR-1t board can be installed directly on protoboard or used as shield by other PCB. Also, by adding DIP8 holder you can … Read more
This is tinyAVR (ATtiny13, ATtiny25, ATtiny45, ATtiny85, and other) library for LED controller modules based on TM1638 chip. Modules based on TM1638 provide three signal connections (CLK, STB and DIO) and two power connections (VCC and GND). Signal pins can be connected to any pair of digital pins of the AVR chip. Signal pins configuration is … Read more
This article shows how to make an example project of “running dots & digits” using ATtiny13 and popular 7-segment LED tube display based on MAX7219/MAX7221. Complete code is on GitHub. MAX7219/MAX7221 library for LED tube display A lightweight library for 7-segments LED tube displays based on MAX7219/MAX7221 chip that works with tinyAVR family (ATtiny13, ATtiny25, ATtiny45, … Read more
This example project shows how to make random flickering pixels using ATtiny13 and popular 8×8 matrix LED display based on MAX7219/MAX7221. Complete project code is on GitHub. MAX7219/MAX7221 library for 8×8 matrix LED display A lightweight library for 8×8 matrix LED displays based on MAX7219/MAX7221 chip that works with tinyAVR family (ATtiny13, ATtiny25, ATtiny45, ATtiny85) can … Read more
This article is about tinyAVR (ATtiny13, ATtiny25, ATtiny45, ATtiny85) library for 7-segment display modules based on TM1637 chip. These TM1637 modules provide two signal connections (CLK and DIO) and two power connections (VCC and GND). Signal pins can be connected to any pair of digital pins of the AVR chip. Signal pins configuration is defined … Read more
This is a quick how-to guide of making a minimalist development boards for MCU of tinyAVR family like ATiny13/25/45/85. The idea behind this project was to create an environment for rapid development. I’ve been designing many projects based on this little MCUs and I didn’t want to wire it all up any more by hand. … Read more
