App note: MSP432 platform porting guide

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 […]

App note: Principles of SAWR-stabilized oscillators and transmitters

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

App note: In house unit with bluetooth low energy module hardware user guide

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 […]

App note: Temperature sensor design guide

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, […]

Breadboard limitations

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 […]

More on PIC configurable logic cells

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 […]

A guide for using IMU devices

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 […]

Updated Bus Pirate documentation

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 […]
