AMOLED DESK CLOCK / ESP32 APPLICATION
SimpleClock
Big, burn-in-aware digits on a square AMOLED desk clock.
About this project
About this project
The whole 480x480 square AMOLED is used as a clock face: hours and minutes in tabular columns, seconds tucked into a corner, weekday, month and two-digit day in a side column that swaps sides every hour, and the entire face drifting 1 px a minute around a 12 x 12 loop to fight burn-in. A Waveshare ESP32-C6-Touch-AMOLED-2.16 brings the CO5300 panel, CST9220 touch, AXP2101 PMU, PCF85063 RTC and QMI8658 accelerometer; no soldering or extra parts are needed. Time syncs over NTP every hour and survives offline in the RTC, whose drift is measured and corrected. Wi-Fi is set from a .env file or by the clock's own hotspot with a QR code, and settings live at clock.local in Traditional Chinese or English. PlatformIO builds it; the first toolchain download is about 7 GB.
