resolution of micros

[herbkonik]

Hi,
using micros at an Atmega328P board the resolution is 4 micros (if i understand the arduino reference right).
Dos the LGT boards have the same resolution or is it different ?

At 32Mhz (no prescaler), the resolution of micros is 2 us.

See here:

• lgt8fx/lgt8f/cores/lgt8f/wiring.c

  Line 103 in df986b5

  return ((m << 8) + t) * (64 / clockCyclesPerMicrosecond());

• lgt8fx/lgt8f/cores/lgt8f/Arduino.h

  Line 110 in df986b5

  #define clockCyclesPerMicrosecond() ( F_CPU / 1000000L )

• And the fact that F_CPU is 32,000,000 (when no prescaler is set)
