Wire Library Not Working with Serial: Enhancing the Communication Experience

The Arduino Wire library, a fundamental component in many projects, has been a cornerstone for communication between microcontrollers and peripherals. However, its limitations have led to the quest for enhancements and improvements. One of the most pressing issues is the lack of non-blocking functionality in the serial communication protocol. In this article, we'll explore potential solutions and propose additions to the Wire library to make it more versatile and efficient.

One possible approach is to add support for master mode, which would enable developers to request data transmission without blocking the main program flow. This could be achieved by introducing new functions, such as `requestFrom` with a callback function parameter. This would allow the developer to specify a function to be executed when the transfer completes, rather than blocking the program until the operation is finished.

For instance, the revised `requestFrom` function could accept an additional optional parameter, `function`, which would be called when the transmission is complete. This would enable developers to write non-blocking code that can handle other tasks while waiting for data reception or transmission.

Another potential solution is to introduce a complete function that combines the functionality of `requestFrom` and `endTransmission`. This would provide a more comprehensive way of handling serial communication, allowing developers to specify both the address and the length of the transfer, as well as a callback function to be executed when the operation is complete.

The current implementation of the Wire library includes two blocking functions: `endTransmission` and `requestFrom`. While these functions are useful for simple applications, they can become restrictive in more complex projects that require non-blocking communication. By adding non-blocking functionality, developers could write more efficient and responsive code that takes advantage of the microcontroller's resources.

The importance of API compatibility cannot be overstated. When multiple developers work together on a project, it is essential to have a consistent and reliable communication protocol. The adoption of non-blocking extensions by the official Arduino Wire library would not only benefit individual developers but also contribute to a more cohesive and efficient development community as a whole.

As we move forward in our quest for innovation, I believe that a non-blocking extension to the Wire library is an essential step towards enhancing the overall communication experience. By collaborating with the Arduino community and contributing to the growth of the project, we can create a more versatile and effective toolset for developers worldwide.
