Serial Data Buffer Management

Introduction to Read Buffer

The readBuffer function is a crucial tool for developers working with serial data in programming environments like Microsoft MakeCode. This function allows users to read available serial data into a buffer, enabling efficient data handling and processing.

Key Features:

• Data Retrieval: Retrieve a specified number of characters from the serial port, or all available data by setting the length to 0.
• Buffer Management: The function returns a buffer containing the input data, which can be used for further processing or display.
• Asynchronous Processing: Users can implement asynchronous data handling, allowing for real-time data processing without blocking program execution.

Use Cases:

• IoT Applications: Ideal for Internet of Things (IoT) projects where devices communicate via serial ports.
• Data Logging: Useful in applications that require logging data from sensors or other serial devices.
• Interactive Displays: Can be used to read data and update displays in real-time, enhancing user interaction.
