Comparison functions
Comparison functions include comparison for 8, 16, and 32-bit integers (Util_cmpUint8, Util_cmpUint16, Util_cmpUint32). The functions compare two values, and return the comparison result in UTIL_CMP_XXX value. For convenience, the following macros have been defined:
- Util_isLtUint{8,16,32}(a,b)
- Util_isGtUint{8,16,32}(a,b)
- Util_isEqUint{8,16,32}(a,b)
- Util_isLtOrEqUint{8,16,32}(a,b)
- Util_isGtOrEqUint{8,16,32}(a,b)
For example:
Low-resolution timer
Low-resolution timers have a granularity of one second. Timers can be added with Util_addTimer(). When a timer is created, the user defines whether the timer is an application timer or not. The application timers generate App_timer() event, other timers must be checked with Util_checkTimer(). A timer can be modified and/or removed with Util_setTimer() function.
