Keil Compiler timer.h Include Function

SoCal

The Microchip Atmega328 compiler provides a timer function, i.e. #include <Timerone.h>, which allows for simple delay coding such as delay (XXX) for millisecond delays or delayMicroseconds(XXX) for delays of microseconds. Does the Keil Compiler for the Silabs EFM8BB1 provide a timer.h function?

    Here is the SiLabs reply;

    No, you have to write your own delay_ms(), delay_ms(), functions! If it's just delay func.(controller do nothing, just stay in some loop) here is sample functions:
    void delay_us(unsigned int usec){
     unsigned int i;
        for(i = 0; i < usec; i++){        
            ;//j++;
        }
    }
    void delay_ms(unsigned int msec){
     unsigned int i, j;
        
        for(i = 0; i < msec; i++){        
            for(j = 0; j < 2400; j++){        
                ;// Wait!
            }
        }
    }
    , which are valid for "SYSCLK=24Mhz"!
    If you don't want controller to stay in 'delay loop', you have to use any  timer as systick timer with or without using interrupt!
