This library is a rebrand of the Ticker library, because of naming conflicts with ESP based microcontrollers which is also a problem with mbed based Arduino devices like Raspberry Pi Pico or Arduino ...

TSR ：中断回调函数， 不能带参数， 不能有返回值。 一. 初识LiLyGO T-CALL 根据原理图, 我们可以得到以下结论 1.SIM800L电源使能引脚接在ESP32的GPIO23引脚 2.SIM800L开关机引脚接在ESP32的GPIO4引脚 3.SIM800L复位引脚接在ESP32的GPIO5引脚 4. SIM800L的串口接在了ESP32的26, 27引脚 二 ...

This library implements 64 bit time counters optional with offset. It also provides 32 bit versions with optional offset. These functions were inspired by code from docdoc to count millis() rollOvers.
