Rui Santos has written an article on SP8266 troubleshooting guide: The ESP8266 has a few common issues, specially when you are trying to flash a new firmware or uploading scripts. This is a companion guide to the Home Automation using ESP8266 and Password Protected Web Server eBooks. Here’s a compilation with some of the most […]
Here’s a MSP432 platform porting guide from TI, app note here (PDF!): The goals for this porting guide is to help developers accurately assess the effort to port an existing application from one MSP platform to another, ultimately to derive a porting strategy with complete hardware and software coverage that properly ports the existing application without introducing bugs due to […]
Principles of SAW-stabilized oscillators and transmitters from EPCOS, app note here (PDF!) This application note describes the physical principle of SAW-stabilized oscillator. Oscillator structures for one- and two-port SAW resonators are discussed. An application example for a 433.92MHz transmitter for keyless entry is given
In house unit with bluetooth low energy module hardware user guide (PDF): This document describes the design details of the In House Unit (IHU) project. It will guide the user to know and start the design based on this IHU board. It gives a clear concept of the entire design. The IHU design with CSR […]
Temperature sensor design guide: In many systems, temperature control is fundamental. There are a number of passive and active temperature sensors that can be used to measure system temperature, including: thermocouple, resistive temperature detector, thermistor and silicon temperature sensors. These sensors provide temperature feedback to the system controller to make decisions such as, over-temperature shutdown, […]
We love breadboards, they make prototyping easy, but they have their limitations. The way breadboards are built imposes a low maximum frequency to the design, typically less then 50 MHz. This is due to the high parasitic inductance and capacitance on solderless breadboards. For designs that work at low frequencies, breadboards are the ideal tool […]
An introduction to the MOSFET: If you need to switch high current and or high voltage loads with a micro controller you’ll need to use some type of transistor. I’m going to be covering how to use a MOSFET since it’s a better option for high power loads. This guide will be just a brief […]
Selector guide: Signal chain 3rd edition Whether you need to meet tight accuracy requirements, reduce form factor size, or lower power consumption, this selector guide will help you choose the right signal chain components to optimize your design. Included are analog multiplexers and switches, ADCs, DACs, operational amplifiers, digital potentiometers, filters, voltage references, resistor-dividers, and […]
An app note about heat management, including an overview of some cool thermocouple-reading ICs: This product guide showcases Maxim’s industry-leading portfolio of thermal-management devices, which includes temperature sensors and switches, fan controllers, and a highly accurate thermocouple-to-digital converter. Learn how to select the right fan controller and improve designs using multichannel temperature sensors. Thanks rsdio!
Here’s some more info on the new PIC microcontrollers with configurable logic cells. felix52 tipped us to a Configurable Logic Cell Tool from Microchip: The intention of this User’s Guide is to assist the reader in becoming acquainted with the Configurable Logic Cell (CLC) Configuration Tool. It will explain how to setup the tool and […]
Another translation from Nick: Self-test guide in russian. All translations are appreciated, and there should be a language selection feature on the wiki soon. The wiki is open to anyone with a forum account. Get your own handy Bus Pirate for $30, including world-wide shipping. Also available from our friendly distributors.
Starlino has a great article on using gyroscopes and accelerometers. I’ll try try to cover few basic but important topics in this article: – what does an accelerometer measure – what does a gyroscope (aka gyro) measure – how to convert analog-to-digital (ADC) readings that you get from these sensor to physical units (those would […]
This practical USB engineering guide provides examples of how to make USB devices and embedded USB hosts. Thanks McZ!
Things we really love, that we think you should have too. Based on Ian’s Hack a Day comment, with additions by Jer, Vimark, and Machine Geek: Aoyue 968, the best 3-in-1 soldering station for about $100. Ian reviewed it on Hack a Day. $100 and up Proxxon TBM220/110 drill, for super clean PCB holes and […]
There’s a freshly updated Bus Pirate menu command and syntax guide on the documentation wiki. This guide consolidates a ton of notes and caveats that were previously spread around tons of smaller posts. It is updated to the firmware v5.2 release candidate. The main Bus Pirate wiki page has also been updated. A lot of […]
