Contributed to the flipperzero-firmware repository by implementing infrared remote data support for the Fujitsu ASTG12LVCC air conditioner, expanding device compatibility for Flipper devices. Developed new infrared data definitions, including Off, Dh, Cool_hi, Cool_lo, Heat_hi, and Heat_lo, to enable reliable end-user control of this AC model. Focused on embedded systems and infrared communication, the work involved data-driven IR mapping and firmware updates, directly addressing a tracked issue and reducing the need for user workarounds. Maintained collaborative development practices through Git-based workflows, ensuring that the new feature integrated smoothly with existing routines and enhanced the overall user experience.
