Hi, Having trouble with sys_timeout() function.
My call to sys_timeout, using a timeout value of 5000 (i.e. 5 seconds). But, the timeout handler function is being called roughly twice per second! I don't understand what is wrong, but I thought it was something to do with these macros in sys_arch.h /* OS20 time conversion macros */ #define time_ticks_per_sec() ST_GetClocksPerSecond() #define tick_to_msec(tick) ((u32_t)((tick) * 1000 / time_ticks_per_sec())) #define msec_to_tick(msec) ((clock_t)((msec) * time_ticks_per_sec() / 1000)) #define tick_to_usec(tick) ((u32_t)((tick) * 1000000 / time_ticks_per_sec())) #define usec_to_tick(usec) ((clock_t)((usec) * time_ticks_per_sec() / 1000000)) The msec_to_tick appears to overflow with a large number (like 5000) - or am I wrong. Anyway, is there another way to implement a timer with a 5 second interval? and why does my timer fire roughly twice per second? On my system the ST_GetClocksPerSecond() equates to 6250,000 .
