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 e-book (pdf) 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.

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

The Raspberry Pi Global Shutter Camera is a specialised 1.6 MP camera from Raspberry Pi that is able to capture rapid motion without introducing artefacts typical of rolling shutter cameras. It is ideally suited to fast motion photography and to machine vision applications, where even small amounts of distortion can seriously degrade inference performance. With a large pixel size of 3.45 x 3.45 ?m providing high light sensitivity, the Global Shutter Camera can operate with short exposure times (as low as 30 ?s with adequate lighting), an advantage for high-speed photography. It features a 1.6 MP Sony IMX296 sensor, and it has the same C/CS-mount lens assembly as the Raspberry Pi High Quality Camera, for compatibility with the same broad variety of lenses. In common with other global shutter sensors, the IMX296 has a lower resolution than similarly sized rolling shutter sensors; a low pixel count is appropriate for machine vision applications, where high-resolution images are challenging to process in real time. The Global Shutter Camera's lower resolution means that with appropriate lens magnification, an image suitable for processing by a machine vision model can be captured natively. The Raspberry Pi Global Shutter Camera is compatible with any Raspberry Pi computer that has a CSI connector.

This small mono amplifier is surprisingly powerful – able to deliver up to 2.5 W into 4-8 Ω impedance speakers. Inside the miniature chip is a class D controller, able to run from 2.0-5.5 V DC. Since the amplifier is a class D, it's very efficient making it perfect for portable and battery-powered projects. It has built-in thermal and over-current protection. There's even a volume trim pot so you can adjust the volume on the board down from the default 24 dB gain. The A+ and A- inputs of the amplifier go through 1.0 µF capacitors, so they are fully 'differential' – if you don't have differential outputs, simply tie the Audio-pin to ground. The output is 'Bridge Tied' – that means the output pins connect directly to the speaker pins, no connection to ground. The output is a high frequency 250 KHz square wave PWM that is then 'averaged out' by the speaker coil – the high frequencies are not heard. All the above means that you can't connect the output into another amplifier, it should drive the speakers directly. The amplifier comes with a fully assembled and tested breakout board, a header to plug it into a breadboard and a 3.5 mm screw-terminal blocks so you can easily attach/detach your speaker. Speaker is not included, we recommend using any 4 Ω or greater impedance speaker. Features Output Power: 2.5 W at 4Ω, 10% THD (total harmonic distortion), 1.5 W at 8 Ω, 10% THD, with 5.5 V Supply 50 dB PSRR (power supply rejection ratio) at 1 KHz Filterless design, with ferrite bead + capacitors on output. Fixed 24 dB gain, an onboard trim potentiometer for adjusting input volume. Thermal and short-circuit/over-current protection Low current draw: 4 mA quiescent and 0.5 mA in shutdown (due to pull-up resistor on SD pin)
