9-16: Consider using official documentation links.The introduction provides a good overview of the QN8027's capabilities. However, the datasheet and Hardware Application Note are currently linked to a GitHub repository. It would be preferable to link to the manufacturer's official documentation if available, as this ensures users are accessing the most up-to-date and authoritative information.
30-133: Consider adding comments to explain less obvious parameters.The example configuration is comprehensive and well-structured, covering various aspects of the QN8027 setup. To enhance user understanding, consider adding inline comments to explain the purpose or impact of less obvious parameters, especially in the
qn8027configuration block.For example:
qn8027: id: fm_transmitter frequency: 87.50 # Set the FM transmission frequency in MHz frequency_deviation: 74.82 # Adjust the frequency deviation for audio quality # ... (add similar comments for other parameters)This will help users better understand the configuration options and their effects.
135-152: Clarify the purpose of multiple frequency-setting methods.The API services for 'set_url' and 'set_frequency' are well-defined and provide useful functionality. However, the 'set_frequency' service demonstrates three different ways to change the frequency:
- Using the number component
- Using the qn8027.set_frequency action
- Using a lambda function
While this is informative, it might be confusing for users. Consider adding a comment explaining why these multiple methods are shown (e.g., to demonstrate different approaches) or choose the recommended method and remove the others to avoid confusion.
179-179: Reconsider including undocumented register information.The note about the undocumented register (reg30) provides potentially useful information for advanced users. However, including details about undocumented features in official documentation can lead to issues:
- It may confuse less experienced users.
- The behavior of undocumented features might change in future hardware revisions without notice.
- It could encourage users to rely on unofficial functionality.
Consider either removing this information or moving it to a separate "Advanced Usage" or "Developer Notes" section with appropriate warnings about its unofficial nature.
