We all know that, Atmega328 IC is used in Arduino UNO board. This IC is the brain of the Arduino board. Actually, Arduino designers wanted to make a handy prototyping board for the beginners so they ...

While newer Arduinos and Arduino compatibles (including the Hackaday.io Trinket Pro. Superliminal Advertising!) either have a chip capable of USB or rely on a V-USB implementation, the old fogies of ...

This repository contains the bootloader for Adafruit nRF52832 boards (512KB flash, 64KB SRAM). It is based on nRF52 SDK 11.0.0 using the classic serial and OTA update options, and adds the following ...

This repository contains a customized version of the Arduino bootloader firmware with watchdog timer (WDT) support. The stock Arduino bootloader introduces a couple of seconds of delay during boot in ...

Signed and encrypted updates – MCUboot has support for encrypting/decrypting images on-the-fly while upgrading. It will also check if the computed signature is matching the one embedded in the image ...

Security is something that’s far too often overlooked in embedded devices. One of the main risks is that if the device doesn’t verify the authenticity of incoming firmware updates. [Walter Schreppers] ...
