Background

I just took on a new project, doing c++ page development. Since I hadn't been involved in this kind of development before, I'm writing down the process here and also commemorating the approximately 20 days of development. About 50% of the time was spent getting familiar with lvgl development, its rendering process, syntax, APIs, and so on. Around 30% of the time was used for compilation and testing, and only the remaining time was actually used for writing code. During this process, the newly added logic led to a continuous growth of corresponding code branches, which required me to spend more time understanding the code later. In the end, I managed to complete the task, but I'm not entirely satisfied with the overall robustness, cleanliness, and readability of the code.
