This thesis explores the design and implementation of a Human Machine Interface (HMI) and microcontroller system for the Wrepair Powerstation, a charging and data transfer station for smart devices. The project focuses on developing an intuitive touchscreen interface for real-time monitoring and control of power allocation across multiple USB-C ports. The system allows users to adjust the power output of each port while respecting the limitations of connected devices and the overall power budget of the charging station. The adjustable power allocation system improves the user experience by enabling users to prioritize certain devices for faster charging. This optimization enhances charging efficiency and provides greater flexibility in managing power distribution among connected devices. The thesis also discusses the selection and integration of a suitable microcontroller to manage communication between power delivery modules, the touchscreen display, and other system components. The goal is to create a user-friendly and reliable Powerstation that meets the needs of professionals in the electronics repair industry.
