  • The ESP32 Cheap Yellow Display Book (PDF) - Elektor

    Elektor Digital The ESP32 Cheap Yellow Display Book (PDF)

    Projects Using Arduino IDE and the LVGL Graphics Library The ESP32 is probably one of the most popular microcontrollers used by many people, including students, hobbyists, and professional engineers. Its low cost, coupled with rich features makes it a popular device to use in many projects. Recently, a board called the ESP32 Cheap Yellow Display (CYD for short) is available from its manufacturers. The board includes a standard ESP32 microcontroller together with a 320x240 pixel TFT display. Additionally, the board provides several connectors for interfaces such as GPIO, serial port (TX/RX), power and Ground. The inclusion of a TFT display is a real advantage as it enables users to design complex graphics-based projects without resorting to an external LCD or graphics displays. The book describes the basic hardware of the ESP32 CYD board and provides details of its on-board connectors. Many basic, simple, and intermediate-level projects are given in the book based on the ESP32 CYD, using the highly popular Arduino IDE 2.0 integrated development environment. The use of both the basic graphics functions and the use of the popular LVGL graphics library are discussed in the book and projects are given that use both types of approaches. All the projects given in the book have been tested and are working. The block diagram, circuit diagram, and the complete program listings and program descriptions of all the projects are given with explanations. Readers can use the LVGL graphics library to design highly popular eye-catching full-color graphics projects using widgets such as buttons, labels, calendars, keypads, keyboards, message boxes, spinboxes, sliders, charts, tables, menus, bars, switches, drop-down lists, animations, and many more widgets.

    Ce boîtier dissipateur thermique en aluminium anodisé protégera votre Raspberry Pi 4 et vous offrira un refroidissement passif très efficace. C'est idéal dans les cas où vous souhaitez un refroidissement totalement silencieux, par exemple si vous construisez un centre multimédia domestique. La livraison comprend un tampon thermique pour assurer le contact thermique entre le processeur et le boîtier supérieur, ainsi qu'une clé Allen pratique et un jeu de boulons hexagonaux pour fixer le boîtier ensemble. Le boîtier vous donne accès à tous les ports, broches et connecteurs. Caractéristiques Boîtier supérieur et inférieur en aluminium anodisé Dissipateur thermique finlandais Chemin thermique Boulons hexagonaux et clé Allen inclus Accès à tous les ports, broches et connecteurs Compatible avec Raspberry Pi 4 Assemblée L'assemblage de votre boîtier de dissipateur thermique est assez simple et ne devrait prendre que quelques minutes. La première et la plus importante chose est de vous assurer que votre Pi est éteint et débranché avant d’installer le boîtier. Prenez l'un des tampons thermiques et décollez les films protecteurs des deux côtés (il y a un film blanc et un film transparent facile à manquer de l'autre côté. Collez le tampon thermique sur le processeur de votre Pi (le carré métallique le plus proche du milieu). du PCB). Coller d'abord le tampon thermique sur le processeur est une bien meilleure façon de le positionner correctement que d'essayer de le coller sur le boîtier. N'utilisez qu'un seul tampon thermique avec le Raspberry Pi 4 . Positionnez le top case puis, en le maintenant en place, retournez le tout et positionnez le bottom case sur la face inférieure de votre Pi. Utilisez les quatre boulons hexagonaux et toutes les clés pour fixer le boîtier. Remarques Le boîtier est en métal et donc conducteur, veillez donc à ne court-circuiter aucun composant et assurez-vous que votre RPi est éteint et débranché lors de l'installation du boîtier. Cela peut paraître évident, mais le boîtier deviendra chaud à l'usage Dimensions : 87 × 56 × 25,5 mm

  • Hands - on Microcontroller Course for Advanced Arduino Users - Elektor

    Elektor Publishing Hands-on Microcontroller Course for Advanced Arduino Users

    32 new Projects, Practical Examples and Exercises with the Elektor Arduino Nano MCCAB Training Board Electronics and microcontroller technology offer the opportunity to be creative. This practical microcontroller course provides you with the chance to bring your own Arduino projects and experience such moments of success. Ideally, everything works as you imagined when you switch it on for the first time. In practice, however, things rarely work as expected. At that point, you need knowledge to efficiently search for and find the reason for the malfunction. In this book for advanced users, we delve deep into the world of microcontrollers and the Arduino IDE to learn new procedures and details, enabling you to successfully tackle and solve even more challenging situations. With this book, the author gives the reader the necessary tools to create projects independently and also to be able to find errors quickly. Instead of just offering ready-made solutions, he explains the background, the hardware used, and any tools required. He sets tasks in which the reader contributes their own creativity and writes the Arduino sketch themselves. If you don’t have a good idea and get stuck, there is, of course, a suggested solution for every project and every task, along with the corresponding software, which is commented on and explained in detail in the book. This practical course will teach you more about the inner workings of the Arduino Nano and its microcontroller. You will get to know hardware modules that you can use to realize new and interesting projects. You will familiarize yourself with software methods such as ‘state machines,’ which can often be used to solve problems more easily and clearly. The numerous practical projects and exercise sketches are once again realized on the Arduino Nano MCCAB Training Board, which you may already be familiar with from the course book ‘Microcontrollers Hands-on Course for Arduino Starters’, and which contains all the hardware peripherals and operating elements we need for the input/output operations of our sketches. Readers who do not yet own the Arduino Nano MCCAB Training Board can purchase the required hardware separately, or alternatively, build it on a breadboard.
