ESP8266 RFID (RC522, PN532, Wiegand, RDM6300) Access Control system featuring WebSocket, JSON, NTP Client, Javascript, SPIFFS

This library enables you to use Interrupt from Hardware Timers on an ESP8266-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 tas…

An "Off-line machine learning" (Offline AI, artificial intelligence) project, in which 2 tensorflow-lite apps are developed to run on Raspberry Pi 3. It hopes to propose a generic method on cross-developing, so that developer could fast follow to get your own apps started on Embedded intelligence (AI embedded system), smart object (AI IoT) and etc.
