Macros

Special time constants
#define TIME_IMMEDIATE   ((sysinterval_t)0)
 Zero interval specification for some functions with a timeout specification. More...
 
#define TIME_INFINITE   ((sysinterval_t)-1)
 Infinite interval specification for all functions with a timeout specification. More...
 
#define TIME_MAX_INTERVAL   ((sysinterval_t)-2)
 Maximum interval constant usable as timeout. More...
 
#define TIME_MAX_SYSTIME   ((systime_t)-1)
 Maximum system of system time before it wraps. More...
 
Fast time conversion utilities
#define TIME_S2I(secs)   ((sysinterval_t)((time_conv_t)(secs) * (time_conv_t)CH_CFG_ST_FREQUENCY))
 Seconds to time interval. More...
 
#define TIME_MS2I(msecs)
 Milliseconds to time interval. More...
 
#define TIME_US2I(usecs)
 Microseconds to time interval. More...
 
#define TIME_I2S(interval)
 Time interval to seconds. More...
 
#define TIME_I2MS(interval)
 Time interval to milliseconds. More...
 
#define TIME_I2US(interval)
 Time interval to microseconds. More...
