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...

This is a self-contained tool to allow you to experiment with the configurable op amps provided in the new AVR DB-series processors from Microchip. It shows the configuration as a circuit diagram on the display, and lets you reconfigure it by selecting options from on-screen menus. The...

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...

AVR DA Product Family are known for real time control functionality and easy capacitive touch to the low power performance of AVR Microcontrollers. It pairs the latest Core Independent Peripherals (CIPs) with a robust Intelligent Analog portfolio to create a device that not only...

Antti Mäntyniemi designed this board, which is a UPDI programmer that utilizes Arduino IDE to program AVR microcontrollers. This kind of programmer is used to programm the new 0-series and 1-series ATtiny mcus using Arduino IDE. The project files are available on github.com so you can...

One of the things I love about JavaScritpt is the fact it keeps finding applications in different domains. One such use is in Arduino, with Espruino (open-source JavaScript interpreter for microcontrollers), and an interesting new one is the AVR8js. AVR8js is an open-source Arduino...

Great Cow BASIC is a robust and fully functional compiler and assembler for 8-bit microchip PIC and Atmel AVR microcontrollers. It was developed to cater for all class of embedded system solution developers from experts to beginners but with a great tool to help beginners. It was...

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...
