Next up, I've fixed those annoying memory protection faults by upgrading LovyanGFX from version 1.1.12 to 1.1.16. Memory faults are like those gremlins in the machine that can cause all sorts of chaos, so getting this sorted was a top priority. LovyanGFX is a vital library for handling the graphical interface of our alarm clock, and keeping it up-to-date ensures smoother performance and fewer crashes. This upgrade addresses several known issues related to memory management, making the application more stable and resilient. No one wants their alarm clock to freeze up, especially when it’s time to wake up!

The memory protection faults were a significant headache, often leading to unpredictable behavior and crashes. By upgrading LovyanGFX, we've incorporated the latest bug fixes and optimizations provided by the library developers. This not only resolves the immediate issue but also sets the stage for future enhancements and features. The process involved replacing the older library files with the new version and verifying that all graphical elements and functionalities worked as expected. The result is a more reliable and user-friendly alarm clock, free from those pesky memory-related hiccups. With this fix in place, we can move forward with confidence, knowing that the graphical interface is solid and dependable.

3. GPIO Pull-Up Configuration for ESP32-C3 Rotary Encoder

To improve the user experience, I've added GPIO pull-up configuration for the ESP32-C3 rotary encoder. This might sound a bit technical, but basically, it makes the rotary encoder more responsive and reliable. A rotary encoder is a key component for interacting with the alarm clock, allowing users to set the time, adjust volume, and navigate menus. By configuring the GPIO pull-ups, we ensure that the encoder signals are clean and consistent, reducing the chance of misreads or erratic behavior. This small tweak can make a big difference in how intuitive and enjoyable the alarm clock is to use.

The GPIO pull-up configuration is essential for ensuring that the rotary encoder functions correctly in various environments. Without it, the encoder signals can be susceptible to noise and interference, leading to inaccurate readings. By adding this configuration, we provide a stable electrical environment for the encoder, ensuring that it accurately detects user input. This involves setting specific pins on the ESP32-C3 to a high state by default, which helps to define a clear signal when the encoder is rotated. The result is a more responsive and reliable interface, enhancing the overall user experience of the alarm clock. With this improvement, users can interact with the device more smoothly and efficiently, making setting the time and other parameters a breeze.

4. SNTP API Calls Updated

I've also updated the deprecated SNTP API calls to the new esp_sntp_* functions. This is crucial for keeping the clock accurate by syncing with network time servers. Using the latest API ensures that our code is up-to-date and compatible with future updates. SNTP (Simple Network Time Protocol) is what allows the alarm clock to automatically set the correct time by communicating with internet time servers. By switching to the esp_sntp_* functions, we’re using the most current and supported methods, which enhances the reliability and accuracy of the time synchronization process. This is a fundamental aspect of any modern alarm clock, ensuring that users wake up on time, every time.

The move to the esp_sntp_* functions was necessary to align with the latest standards and best practices in network time synchronization. The older SNTP API calls were deprecated, meaning they were no longer recommended for use and could be removed in future updates. By making this change, we ensure that our alarm clock remains compatible and maintainable over time. This update involved replacing the old function calls with the new ones and testing the time synchronization process to confirm that it worked correctly. The benefits of this change are numerous, including improved performance, enhanced security, and greater reliability in obtaining accurate time from network time servers. This ensures that the alarm clock remains a dependable tool for users, providing the correct time and waking them up as scheduled.

5. ADC Configuration Fixed

A little bug fix here – I've corrected the ADC configuration by adding the missing clk_src initializer. ADC (Analog-to-Digital Converter) is used for reading analog signals, like the microphone input for voice control features. Ensuring the ADC is properly configured means we can get accurate readings and avoid potential issues down the line. The clk_src initializer specifies the clock source for the ADC, which is essential for its proper functioning. Without this, the ADC might not operate correctly, leading to inaccurate readings or even system instability. By adding this missing piece, we’ve ensured that the ADC works as intended, paving the way for future enhancements that rely on analog signal processing.

The ADC configuration is a critical aspect of the alarm clock's hardware interface, allowing it to interact with analog sensors and inputs. By including the clk_src initializer, we ensure that the ADC operates with the correct timing and frequency, resulting in accurate and reliable readings. This fix is particularly important for features that involve audio input or other analog measurements, as it guarantees that the data captured is precise and consistent. The process involved identifying the missing initializer in the ADC setup code and adding it to the configuration sequence. The result is a more stable and robust system, capable of handling analog signals effectively. With this fix in place, we can explore new functionalities that leverage the ADC, such as voice-activated commands or environmental sensing.

6. Configurable MAX_VOLUME and NTP_UPDATE_INTERVAL_SEC Defines

For more flexibility, I've added configurable MAX_VOLUME and NTP_UPDATE_INTERVAL_SEC defines. This means you can now tweak the maximum volume and how often the clock syncs with the network time servers. These are just some handy settings to have, especially if you have specific preferences or need to optimize power consumption. The MAX_VOLUME define allows users to set the maximum sound level for the alarm, preventing it from being too loud or disturbing. The NTP_UPDATE_INTERVAL_SEC define controls how frequently the alarm clock checks for time updates from the network, balancing accuracy with power usage. By making these settings configurable, we provide users with greater control over their alarm clock experience.

The ability to configure the MAX_VOLUME and NTP_UPDATE_INTERVAL_SEC provides a significant level of customization for users. For example, someone living in a quiet environment might want to reduce the maximum volume to avoid startling themselves awake, while others might prefer a louder alarm to ensure they wake up on time. Similarly, the frequency of NTP updates can be adjusted based on the user's needs and network conditions. A shorter update interval ensures greater time accuracy, but it also consumes more power. A longer interval reduces power consumption but may result in slight time deviations. By exposing these settings, we empower users to tailor the alarm clock to their specific requirements and preferences. This flexibility is a key aspect of a modern and user-friendly device.

7. Audio Stop on Initialization and Volume Debug Output Added
