Function rpi_pico_sdk_sys::time_us_64

pub unsafe extern "C" fn time_us_64() -> u64

\brief Return the current 64 bit timestamp value in microseconds \ingroup hardware_timer

Returns the full 64 bits of the hardware timer. The \ref pico_time and other functions rely on the fact that this value monotonically increases from power up. As such it is expected that this value counts upwards and never wraps (we apologize for introducing a potential year 5851444 bug).

\return the 64 bit timestamp
