TinyICOC – AVR In-Circuit Oscillator Calibrator

Stefan Wagner published another great project on Github. He writes: Sometimes AVRs are operated without an external clock. The internal oscillator does a good job in most applications, but when it comes to precise timing, it is too inaccurate. The accuracy of the oscillator of an AVR...

A full-duplex tiny AVR software UART

UARTs for AVR MCUs by Nerd Ralph, he writes: I’ve written a few software UARTs for AVR MCUs. All of them have bit-banged the output, using cycle-counted assembler busy loops to time the output of each bit. The code requires interrupts to be disabled to ensure accurate timing between...

Minimal I2C for the New AVR Microcontrollers

This article describes a set of minimal I2C routines for the new 0-series and 1-series ATtiny and ATmega microcontrollers. They allow any of these processors to act as an I2C Master and connect to I2C peripherals. As an example of their use I've designed a digital clock circuit based on...
