Timers

Purpose

• Set up the data structure to operate the device.
• Basic read and set time

Description

• The RP2040 has one, the RP2350 two hardware timers, with four alarms each.
• The timer is 64 bits, hence reading the full time requires two register accesses.
• Many timing application can get away with only reading the lower 32 bits, if roll-over is taken into account.
• SetTime should only be used for development/debugging purposes, since doing so may interfere with other processes using the timing features, including the alarms.
