Python UPDI driver for programming "new" tinyAVR and megaAVR devices
This repository is no longer maintained. Use the serialupdi feature of pymcuprog.
pyupdi functionality has been incorporated as a part of pymcuprog:
- install from pypi:https://pypi.org/project/pymcuprog/
- browse the source:https://github.com/microchip-pic-avr-tools/pymcuprog/tree/main/pymcuprog/serialupdi
pymcuprog can be installed as a CLI, or used as a library, and new devices will be added continuously.
If you have a Microchip debugger (eg: Atmel-ICE, PICkit4) you can also use pymcuprog with AVR UPDI devices.
pyupdi is a Python utility for programming AVR devices with UPDI interfaceusing a standard TTL serial port.
Connect RX and TX together with a suitable resistor and connect this nodeto the UPDI pin of the AVR device.
Be sure to connect a common ground, and use a TTL serial adapter running atthe same voltage as the AVR device.

When running pyupdi on Raspberry pi, use GPIOs 14 and 15 for UART TX and RX.On rpi3, be sure to apply the device tree overlay to map UART0/ttyAMA0 to these pins (relocate or disable Bluetooth device).More information here:https://www.raspberrypi.org/documentation/configuration/uart.md
Installpyupdi.py withpip directly from GitHub:
pip install https://github.com/mraardvark/pyupdi/archive/master.zip
