Fernando Ortega enhanced the tasmota/docs repository by consolidating and clarifying documentation for ESP32 ADC GPIO pins. He focused on improving the accuracy of analog input configuration by correcting the documented number of ADC-capable pins, detailing ADC1 and ADC2 channel mapping, and specifying pin behavior regarding pull-up and pull-down resistors. Using Markdown and leveraging his expertise in embedded systems and technical writing, Fernando aligned ADC.md and ESP32.md for consistency, explicitly noting pins without internal pull resistors to reduce misconfiguration risks. His work increased documentation reliability, supporting developer onboarding and reducing support overhead through clear, traceable updates and comprehensive technical guidance.
