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 is a quick how-to guide of making a minimalist development boards for MCU of tinyAVR, like ATiny2313 or ATiny4313. MBAVR-2 is a second project in series of MBAVR family home-made boards in order to create an nice environment for rapid development. All I did, I did at home. I used toner transfer technique for … 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
The AVR is a modified Harvard architecture 8-bit RISC single-chip microcontroller. The AVR was developed by Atmel in 1996 and was one of the first microcontroller families to use on-chip flash memory for program storage. The AVR microcontoller is like a small computer – includes a CPU, some flash program memory, some SRAM and some … Read more
