Abigail Parsons developed a two-digit seven-segment display driver for the lhr-solar/Embedded-Sharepoint repository, enabling hardware indicators and counters to display values from 0 to 99. She implemented the driver in C, focusing on embedded systems and microcontroller programming, with careful attention to GPIO control for accurate digit rendering. The driver supports initialization, single- and double-digit display, and a turn-off function, addressing the need for user-visible feedback in embedded applications. Abigail also created automated tests to verify correct display output for a range of values, demonstrating thoroughness in validation and ensuring the feature’s reliability for real-world hardware integration scenarios.
