De ESP8266 is een indrukwekkende, goedkope WiFi module die geschikt is om WiFi functionaliteit toe te voegen aan een bestaand microcontroller project via een UART seriële verbinding. De module kan zelfs worden geherprogrammeerd om te fungeren als een standalone WiFi connected device – voeg gewoon stroom toe! 802.11 b/g/n protocol Wi-Fi Direct (P2P), soft-AP Geïntegreerde TCP/IP-protocolstack Deze module is een zelfstandige SOC (System On a Chip) die niet noodzakelijkerwijs een microcontroller nodig heeft om inputs en outputs te manipuleren zoals u normaal gesproken zou doen met bijvoorbeeld een Arduino, omdat de ESP-01 fungeert als een kleine computer. Je kunt dus een microcontroller internettoegang geven zoals het Wi-Fi shield doet bij de Arduino, of je kunt de ESP8266 gewoon programmeren om niet alleen toegang te hebben tot een Wi-Fi netwerk, maar ook te fungeren als een microcontroller, wat de ESP8266 zeer veelzijdig maakt.

De flexibiliteit van de Artemis module start met SparkFun's Arduino core. Je kunt de Artemis module programmeren en gebruiken net zoals je dat met een Uno of een andere Arduino zou doen. De tijd om voor het eerst te knipperen is slechts 5 minuten verwijderd! We hebben de kern vanaf de grond opgebouwd, om hem snel en zo licht mogelijk te maken.Dan de module zelf. Met een afmeting van 10 mm x 15 mm heeft de Artemis module alle ondersteunende schakelingen die je nodig hebt om de fantastische Ambiq Apollo3 processor te gebruiken in je volgende project. We zijn er trots op te kunnen zeggen dat de SparkFun Artemis module de eerste open-source hardware module is waarvan de ontwerp bestanden vrij en gemakkelijk beschikbaar zijn. We hebben de module zorgvuldig ontworpen zodat het implementeren van Artemis in uw ontwerp gedaan kan worden met low-cost 2-layer PCBs en 8mil trace/space.Gemaakt in de USA bij SparkFun's Boulder productielijn, is de Artemis module ontworpen voor consumer-grade producten.

A Guide to Powerful Programming for Embedded Systems
You must be a well-rounded professional to excel in the ever-evolving, rapidly developing embedded design and programming industry. Simply put, when it comes to electronics design and programming, the more topics you can master, the more you’ll flourish at your workplace and at your personal workbench. This shouldn’t be a surprise, as the line between the skills of a hardware engineer and software engineer is blurring. The former should have a good grasp of programming in order to build efficient systems. The latter should understand the details of the design (whether it’s a physical or virtual application) for which he or she is writing code. Thus, to be successful, a modern professional electronics engineer must have a solid grasp of both hardware design and programming.
Assembly Language Essentials is a matter-of-fact guide to Assembly that will introduce you to the most fundamental programming language of a processor. Unlike other resources about Assembly that focus exclusively on specific processors and platforms, this book uses the architecture of a fictional processor with its own hardware and instruction set. This enables you to consider the importance of Assembly language without having to deal with predetermined hardware or architectural restrictions.
You’ll immediately find this thorough introduction to Assembly to be a valuable resource, whether you know nothing about the language or you have used it before. The only prerequisite is that you have a working knowledge of at least one higher-level programming language, such as C or Java.
Assembly Language Essentials is an indispensible resource for electronics engineering professionals, academics, and advanced students looking to enhance their programming skills. The book provides the following, and more:
An introduction to Assembly language and its functionality
Significant definitions associated with Assembly language, as well as essential terminology pertaining to higher-level programming languages and computer architecture
Important algorithms that may be built into high-level languages, but must be done the “hard way” in Assembly language — multiplication, division, and polynomial evaluation
A presentation of Interrupt Service Routines with examples
A free, downloadable Assembler program for experimenting with Assembly

Grove ecosystem: 20 x 40 x 10 mm small size, 4-pin Grove connector to plug and play, Arduino compatible This Grove CAN-BUS Module supports CAN FD(CAN with Flexible Data-Rate) communication, which is an extension to the original CAN protocol as specified in ISO 11898-1 that responds to increased bandwidth requirements in automotive networks. In CAN FD, the data rate (i.e. number of bits transmitted per second) is increased to be 5 times faster than the classic CAN (5 Mbit/s for the data payload only, the arbitration bit rate is still limited to 1Mbit/s for compatibility). It supports AT command which enables simple serial port programming. This Grove CAN-BUS Module is based on GD32E103 with a frequency up to 120 MHz. It has a flash size from 64 KB to 128 KB and an SRAM size from 20 KB to 32 KB.
