serial_STWBC2

An open source, header-only library to analyze serial data from the STWBC2 Qi transmitter.

Overview

The serial_STWBC2 library is designed to simplify the parsing and analysis of serial messages sent by the STWBC2 Qi transmitter. It is implemented in C++ and encapsulated in a single header file, making it easy to integrate into your project.

This library:

• Is header-only – simply include the header file in your project.
• Provides a Data structure that holds key parameters such as:
  • state – current state of the transmitter.
  • frequency – operating frequency.
  • controlError – control error value.
  • dutyCycle – duty cycle percentage.
  • bridgeVoltage – voltage at the bridge.
  • rxPower – received power.
  • inputVoltage – input voltage.
• Implements helper functions to resolve the various fields from the raw serial data.
• Uses a simple loop-based mechanism to collect and process serial messages.

Features

• Header-Only Library: No need to compile or link additional files.
• Simple API: Initialize with a serial port and call the loop function to continuously process incoming data.
• Customizable: Designed to work with any platform supporting a Stream class (commonly used in Arduino environments).

Installation

1. Download the Library:

   • Clone the repository:

     git clone https://github.com/KochC/serial_STWBC2.git

   • Or download the ZIP file from the repository page and extract it.

2. Include in Your Project:

   • Copy the include/stwbc2.h file into your project.
   • In your source file, include the header:

     #include "stwbc2.h"

Usage

Below is an example of how to use the library in your project:

#include "stwbc2.h"

// Assume 'Serial' is your instance of Stream (e.g., on Arduino)
void setup() {
  // Initialize the serial communication, if needed
  Serial.begin(9600);

  // Initialize the STWBC2 library with your serial port
  STWBC2::init(&Serial);
}

void loop() {
  // Process incoming serial data
  STWBC2::loop();

  // Use the parsed data from the STWBC2::data structure
  // For example, print the frequency:
  Serial.print("Frequency: ");
  Serial.println(STWBC2::data.frequency);
}

API Reference

Initialization

• void STWBC2::init(Stream *serialPort)
  Set the serial port from which the STWBC2 data will be read.

Data Processing

• void STWBC2::loop()
  Continuously read incoming serial data, build messages, and parse them into the STWBC2::data structure.

Data Structure

• STWBC2::Data
  Holds the parsed data with the following fields:
  • uint8_t state
  • uint32_t frequency
  • uint16_t controlError
  • double dutyCycle
  • double bridgeVoltage
  • double rxPower
  • double inputVoltage
