ESP32-C3 + OLED desk monitor: live CPU/GPU/RAM/disk stats from a Windows/Linux companion app, and 12 animated retro clock styles when the PC sleeps.

This library enables you to use Interrupt from Hardware Timers on an ESP32-based board. It now supports 16 ISR-based timers, while consuming only 1 hardware Timer. Timers' interval is very long (ulong millisecs). The most important feature is they're ISR-based timers. Therefore, their executions are not blocked by bad-behaving functions or tasks…
