Introduction - ESP32 has two I2S peripherals. If you use Linux or *BSD, you can use timersub() to subtract two struct timeval values, which might be what you want. You have two choices for getting a microsecond timestamp. Let's take a closer look at the conversion formula so that you can do these conversions yourself with a calculator or with an old-fashioned pencil and paper. The first (and best) choice, is to use the timeval type directly: The second, and for me less desirable, choice is to build a uint64_t out of a timeval: struct timeval contains two components, the second and the microsecond. This table provides a summary of the Time units within their respective measurement systems. gettimeofday() - Why use both seconds and microseconds? how to print time in micro seconds using ctime() function? Let's take a closer look at the conversion formula so that you can do these conversions yourself with a calculator or with an old-fashioned pencil and paper.
