what is the most accurate way in FreeRTOS to convert tick counts to milliseconds?

hey guys, I’m working on an embedded system running FreeRTOS on an ARM Cortex-M4 microcontroller clocked at 72MHz. I need to measure the execution time of a specific code block to optimize performance. The code snippet using “`xTaskGetTickCount“` provides tick counts, but I need the time in milliseconds for better analysis. Considering the clock speed, what is the most accurate way in FreeRTOS to convert tick counts to milliseconds and achieve millisecond-level resolution for measuring code execution time? @Middleware & OS

  1. ZacckOsiemo#0000

    so you have 72M ticks per a second. Ok your task takes from tickX to tickY. So taskTicks is tickY – tickX. from there is just some sums to ms?

  2. Dtynin#0000

    Ok thanks, but are there any conversion model, after carrying out this action to convert to milliseconds?

  3. ZacckOsiemo#0000

    No just math its basic 1000ms = 72M ticks, ?ms = taskTicks
