This is defined in sdkconfig.h: WebJul 9, 2024 · I think the only compelling reason is that the macro does the multiplication first and can be used with tick rates higher than 1000Hz without a division by zero error. (Although ESP-IDF doesn't support tick rates higher than 1000Hz.) For the same reason it may also be more accurate for some combinations of tick rate and delay in milliseconds.
