cojson tutorial

1. Getting Started To start using cojson parser/generator you need to define the structure of your JSON object by mapping its elements to cojson elements, bind them to members of your C++ class (see Section 2), implement the interfaces for the data streams you have, and build cojson library with your application (see Section 3).

cojson – a JSON parser for constrained platforms

Introduction cojson is a C++ pull-type JSON parser/serializer for constrained platforms, such as bare metal applications on low-end MCUs. It does not use memory allocation and has almost no external dependencies. It is not intrusive – it neither forces nor implies any particular design of the application. Instead it adapts to fit any existing application […]

Моторес додаток для Android смартфону

Вступ Бензинові двигуни в косарках, мотоблоках та садових тракторах потребують регулярного обслуговування (заміни оливи, повітряного фільтра, тощо) кожні 20-30 годин роботи. Цей додаток допоможе відстежувати мотогодини в ручному режимі, коли користувач власноруч ініціює події пуску і зупинки, чи у напівавтоматичному режимі через "прислуховування" до шуму. Коли лічильник мотогодин досягне відмітки в графіку обслуговування, додаток відобразить […]

Motores app for Android phones

Introduction Petrol engines used in lawnmowers, tillers, garden tractors require regular maintenance (such as changing oil, air cleaner, etc) every 20-30 hours of runtime. This app helps tracking engine runtime in manual mode, when user initiates start and stop events or in semi-automatic mode by "listening" to the noise. Once engine's runtime reaches a point […]

Simple RJ45-pluggable IR-repeater

Design of this IR-repeater is based on a photo detector TSMP58138 made by Vishay. This detector differs from many others of this kind by the carrier out signal. The datasheet gives a sample circuit for a repeater application. This design offers slightly modified circuit with visual feedback and an implementation in form of a RJ45 […]
