ATtiny13 – TM1637 Library

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

ATtiny13 – pseudo random numbers

Many applications require random data to feed their algorithms. One would say that it’s quite easy when we can use a function from an existing cryptographic library. However, even if we can use such function like for example rand() from stdlib, it can quickly turn out, that this feature consume more then a half of … Read more
