Developed and integrated the ADC128D818 Analog-to-Digital Converter Library within the arduino/library-registry, expanding hardware compatibility for developers working with ADC128D818 devices. Focused on embedded systems and library development, the work involved designing a library that streamlines the process of interfacing Arduino projects with the ADC128D818 chip. The implementation, written in plaintext and leveraging Arduino-specific conventions, aimed to simplify integration and broaden the range of supported analog-to-digital converters in the registry. No major bugs were reported or addressed during this period, reflecting a focused effort on feature delivery and robust initial implementation rather than ongoing maintenance or bug fixing.
