If you have ever programmed an AVR microcontroller with a USB to serial adapter, you should know how it sometimes gets messy with all the data and power wires. Therefore, Adafruit created a UPDI programmer tool that can program newer tinyAVR and megaAVR chips with only 3 wires! What is...

A UPDI USB programmer (Unified Program and Debug Interface) is basically an Atmel / Microchip proprietary programming interface used for some AVR microcontrollers like the ATtiny series. AVR is an 8-bit RISC architecture microcontroller that is developed by Atmel. With the newer...

Simple UPDI programmer for tinyAVR, megaAVR and AVR-Dx microcontrollers with voltage selection switch (5V and 3.3V). The programmer works with pyupdi as well as with the Arduino IDE as "SerialUPDI with 4.7k resistor or diode". It is based on the USB-to-serial chip CH340N. SerialUPDI...

OMZLO has posted details about baremetal programming on the new TinyAVR MCUs. In their blog post, they describe how to program a blinky firmware on an Attiny406, from the ground up, using the simplest tools. Most of the things described can be easily transposed to other TinyAVR MCUs....

Thanks to the increased popularity of the recent ATtiny series of microcontrollers, there has been an increase in the number of open-source UPDI programmers out there. We have covered quite a number of them including the brilliant UPDI programmer compatible with Arduino IDE but we...

In May, Arduino released a guide on how you can create a UPDI programmer for under $10. Now Dlloydev has posted a guide on Github how to make an Arduino Nano HV UPDI programmer. The Nano HV UPDI programmer will enable you to use the additional configuration settings for the UPDI pin...

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...

Thanks to their tiny size and improved capabilities, the ATtiny-0-Series of microcontrollers have been a delight for designers and DIYers looking for a microcontroller with the ease of use associated with the Arduino boards, but with a way smaller form factor associated with ATtiny...
