PROFILE
Daniel Peng
Daniel Peng contributed to the Dasharo/coreboot repository by enabling new hardware features and improving device reliability over a two-month period. He developed ILIT2901 touchscreen support and laid the foundation for LTE integration, focusing on I2C communication, GPIO management, and device driver development in C. Daniel also delivered HDMI support for the Glassway variant, implementing configuration options and power sequencing to prevent hardware conflicts. He addressed a touchscreen timing bug by refining reset and enable delays based on engineering measurements. His work demonstrated depth in embedded systems and firmware development, resulting in broader hardware compatibility and more robust device initialization processes.
