when I test the simple socket server sample, it be required sys_timer andhigh_res_timer. how to use it .where? when ? thanks !
sys_timer is the main timer, used for OS scheduling, periodic interrupt, system ticks counting, and so on.high_res_timer is not mandatory; you may optionally use it in your application for performance measurements. For example you can associate it to the HAL timestamp driver and accurately measure execution times of pieces of code.
--- Quote Start --- the sys_timer is for sys_clk_timer(nios ii bsp editor->common->main->) and other is for timestamp_timer? --- Quote End --- That's correct. Anyway, as Kirska said, they both are actually generic interval timer components. So you could possibly define two other timers, call them timer1 and timer2 and assign them to sys_clk_timer and timestamp_timer in bsp editor.
