ESP

In ESP32 programmeren voor beginners bekijken we de ESP32 en zijn voorganger, de ESP8266. Deze kleine, maar zeer krachtige Chinese chips bestaan uit een processor, geheugen, input- en outputaansluitingen en hebben draadloze netwerktoegang via WiFi.Met dit boek tonen we hoe de programmeeromgeving Arduino werkt en hoe die kan gebruikt worden met ESP-hardware. Aan de hand van voorbeelden en projecten verduidelijken we hoe de ESP-hardware kan worden toegepast.In vogelvlucht: We beschrijven de opbouw van ESP-experimenten. We tonen hoe displays worden aangesloten. Eeprom_24c16 demonstreert hoe een externe geheugenchip wordt gebruikt om getallen en tekst op te slaan en weer uit te lezen. Project Klok is de eenvoudige implementatie van een digitale klok. We geven een handleiding voor het gebruik van temperatuur- en luchtvochtigheidsensoren. Webclient laat zien hoe de ESP32 gegevens van het internet kan halen. Met Webserver kunnen we op afstand met een pc of smartphone gegevens halen uit een ESP32, sensoren uitlezen en toestellen aan- en uitschakelen. Een NTP-klok haalt tijdinformatie van Tijdserver. Die geeft zowel de tijd als het aantal seconden sinds 1 januari 1900. Het boek beschrijft hoe hieruit de tijd kan worden berekend. In het laatste hoofdstuk gebruiken we het internet om nauwkeurige weerinformatie en voorspellingen op te vragen.

Recently, the development of a tiny chip called the ESP8266 has made it possible to interface any type of microcontroller to a Wi-Fi AP. The ESP8266 is a low-cost tiny Wi-Fi chip having fully built-in TCP/IP stack and a 32-bit microcontroller unit. This chip, produced by Shanghai based Chinese manufacturer Espressif System, is IEEE 802.11 b/g/n Wi-Fi compatible with on-chip program and data memory, and general purpose input-output ports. Several manufacturers have incorporated the ESP8266 chip in their hardware products (e.g. ESP-xx, NodeMCU etc) and offer these products as a means of connecting a microcontroller system such as the Android, PIC microcontroller or others to a Wi-Fi. The ESP8266 is a low-power chip and costs only a few Dollars.ESP8266 and MicroPython – Coding Cool Stuff is an introduction to the ESP8266 chip and describes the features of this chip and shows how various firmware and programming languages such as the MicroPython can be uploaded to the chip. The main aim of the book is to teach the readers how to use the MicroPython programming language on ESP8266 based hardware, especially on the NodeMCU.Several interesting and useful projects are given in the book to show how to use the MicroPython in NodeMCU type ESP8266 hardware: Project “What shall I wear today?”: You will be developing a weather information system using a NodeMCU development board together with a Text-to-Speech processor module. Project “The Temperature and Humidity on the Cloud”: You will be developing a system that will get the ambient temperature and humidity using a sensor and then store this data on the cloud so that it can be accessed from anywhere. Project “Remote Web Based Control”: You will be developing a system that will remotely control two LEDs connected to a NodeMCU development board using an HTTP Web Server application.

Het WeMos D1 mini Pro Board (t.w.v. € 15) wordt automatisch aan uw winkelwagen toegevoegd! Affordable solutions with the ESP8266 and 3D printing If you are looking for a small yet powerful IoT device, you are likely to come across the ESP8266 and compatible products on the market today. One of these, the Wemos/Lolin D1 Mini Pro board strikes a remarkable balance between cost and performance. A small and very affordable prototype board, the D1 Mini Pro stands out with its WiFi functionality and a 16-Mbytes flash memory for easy creation of a flash file system. In addition, there are sufficient input and output pins (only one analog input though) to support PWM, I²C, and One-Wire systems to mention but a few. The book describes the operation, modding, construction, and programming of home appliances including a colorful smart home accessory, a refrigerator/greenhouse controller, an AC powerline monitor, a door lock monitor, and an IKEA Trådfri controller. As a benefit, all firmware developed for these DIY, "IoT-ized" devices can be updated over-the-air (OTA). For most of the designs in the book, a small printed circuit board (PCB) and an enclosure are presented so readers can have a finished and attractive-looking product. Readers having – or with access to! – a 3D printer can "print" the suggested enclosures at home or in a shop. Some of the constructions benefit from a Raspberry Pi configured as a gateway or cms server. This is also described in detail with all the necessary configuring. You don’t need to be an expert but the prerequisites to successful replication of the projects include basic skills with PC software including the ability to surf the Internet. In terms of hardware, you should be comfortable with soldering and generally assembling the PCBs presented in the book. All custom software written for the IoT devices, the PCB layouts, and 3D print files described in the book are available for free downloading.

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.
