During the three years of studying here, I have met many kind and lovely people and received countless help. Your meticulous care has made me feel like a hometown in this strange land, and also helped me to learn and experience a lot in this brand-new cultural environment. Here I want to express my gratitude with a little space. First of all, I appreciate that the University of Navarra - Tecnun gave me this opportunity to do my PhD here in such a beautiful city. Thanks to all the people who work here, your hard work has made each of us extraordinary. Secondly, I would like to thank my mentors, Aitor and Mabel. You are the most patient and selfless professors I have ever encountered. When I was in a low state and evaded reality, it was your effort, tolerance, and kindness that gave me enough courage to face the difficulties again. You have not only taught me the knowledge and way of thinking but also brought me the shining point of humanity. Thank you for everything you have done for me. Also I would like to thank my colleagues: Sergio, Leire, Amaia, Mikel, Iñigo, Juan, and guys who have left school, Angél and Wilmer. You also gave me a lot of help and suggestions after work, I will not forget those happy hours with you. And people at Tecnun and Ceit: i ii Acknowledgement Desmond, Izaro, Elena, and another Sergio, I am glad to meet you. In addition, Josecho's coffee is the best I have ever tasted, because it carries the memories of my talk with you during the coffee break here. Far away in a foreign country, loneliness and incomprehension are the most unbearable burdens. Fortunately, there are several close friends here with me: Eric, Cristina, Zubi, Itu, Roby, and Juan. You have given me a taste of real western life, and I am also very happy to be able to show you the charm of Eastern culture through me. Finally, I want to thank my parents: Guanghan and Zuomei. Thank you for giving me life. It is the love that across the time zone all last long. It makes me realize once again that even when the world's end is coming, when I turn back, I am extremely convinced that you are always there. I understand that these three years have made countless white hairs to your heads, and your cheeks are no longer rosy. Thank you for your silent effort, please let me use my remaining life to repay you well.

Having USB built in allows the chip to act like any USB device. For example, we can program the chip to 'pretend' it's a USB joystick, or a keyboard, or a flash drive! Another nice bonus of having USB built in is that instead of having an FTDI chip or cable (like an Arduino), we can emulate the serial port directly in the chip. This costs some Flash space and RAM space but that's the trade-off. The only bad news about this chip is that it is surface mount only (SMT), which means that it is not easy to solder the way the larger DIP chips are. For that reason, we made a breakout board. The board comes with some extras like a fuse, a 16mhz crystal, USB connector and a button to start the bootloader.

  • Adafruit IO Basics: Color Created by Justin Cooper
    Adafruit IO Basics: Color Created by Justin Cooper Last updated on 2020-08-26 12:06:05 PM EDT Overview This guide is part of a series of guides that cover the basics of using Adafruit IO. It will show you how to send color data from Adafruit IO to a RGB LED. If you haven't worked your way through the Adafruit IO feed and dashboard basics guides, you should do that before continuing with this guide so you have a basic understanding of Adafruit IO. Adafruit IO Basics: Feeds Adafruit IO Basics: Dashboards You should go through the setup guides associated with your selected set of hardware, and make sure you have internet connectivity with the device before continuing. The following links will take you to the guides for your selected platform. Adafruit Feather HUZZAH ESP8266 Setup Guide If you have went through all of the prerequisites for your selected hardware, you are now ready to move on to the Adafruit IO setup steps that are common between all of the hardware choices for this project. Let's get started! © Adafruit Industries https://learn.adafruit.com/adafruit-io-basics-color Page 3 of 30 Adafruit IO Setup The first thing you will need to do is to login to Adafruit IO and visit the Settings page. Click the VIEW AIO KEY button to retrieve your key. A window will pop up with your Adafruit IO. Keep a copy of this in a safe place. We'll need it later. Creating the Color Feed Next, you will need to create a feed called Color.

  • Adafruit ATECC608 Breakout Created by Kattni Rembor
    Adafruit ATECC608 Breakout Created by Kattni Rembor Last updated on 2019-09-17 09:12:37 PM UTC Overview You've got secrets, and you want to keep them safe? Most microcontrollers are not designed to protect against snoopers, but a crypto-authentication chip can be used to lock away private keys securely. Once the private key is saved inside, it can't be read out, all you can do is send it challenge-response queries. That means that even if someone gets hold of your hardware and can read back the firmware, they won't be able to extract the secret! The ATECC608 is the latest crypto-auth chip from Microchip, and it uses I2C to send/receive commands. Once you 'lock' the chip with your details, you can use it for ECDH and AES-128 encrypt/decrypt/signing. There's also hardware support for random number generation, and SHA-256/HMAC hash functions to greatly speed up a slower micro's cryptography commands. © Adafruit Industries https://learn.adafruit.com/adafruit-atecc608-breakout Page 3 of 19 We're starting to see these low-cost secure element chips in various products, so that a less expensive chip can be used to drive peripherals, without worrying about security. This chip does not have a public datasheet, but it is compatible with the ATECC508 earlier version which does, so please refer to that complete datasheet (https://adafru.it/FIg) as well as the ATECC608 summary sheet (https://adafru.it/FIh). The good news is that, despite not having complete documentation, there is some software support.

Mmm isn't it wonderful? All that air around us, which we bring into our lungs, extracts oxygen from and then breathes out carbon dioxide. CO2 is essential for life on this planet we call Earth - we and plants take turns using and emitting CO2 in an elegant symbiosis. But it's important to keep that CO2 balanced - you don't want too much around, not good for humans and not good for our planet. © Adafruit Industries https://learn.adafruit.com/adafruit-scd-40-and-scd-41 Page 3 of 22 The SCD-40 and SCD-41 are photoacoustic 'true' CO2 sensors that will tell you the CO2 PPM (parts-per- million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration (https://adafru.it/PF7) - they really are measuring the CO2 concentration ! That means they're bigger and more expensive, but they are the real thing.

The Adafruit AirLift is a breakout board that lets you use the ESP32 as a WiFi co-processor for a Pico. In this guide, you will wire up a Pico to an AirLift breakout and connect to the internet. Then, you'll learn how to fetch JSON and raw text data from the internet. Finally, an example is included for connecting your Pico to Adafruit IO, the Adafruit internet-of-things service (https://adafru.it/fH9), so you can interact with and visualize your project's data. Why use AirLift? Having WiFi managed by a separate chip means your code is simpler, you don't have to cache socket data, or compile in & debug an SSL library.
