Macro-Based Register Config Helper

Code

#include <stdio.h>
#include <stdint.h>

// Define macros here
#define SET_ENABLE(reg) (reg<<0)
#define SET_MODE(reg) (reg<<1)
#define SET_SPEED(reg) (reg<<3)


uint16_t build_register(uint8_t enable, uint8_t mode, uint8_t speed) {
    // Use macros to set fields

uint16_t temp1 = SET_ENABLE(enable);
uint16_t temp2 = SET_MODE(mode);
uint16_t temp3 = SET_SPEED(speed);


    return temp1|temp2|temp3;
}

int main() {
    uint8_t enable, mode, speed;
    scanf("%hhu %hhu %hhu", &enable, &mode, &speed);

    uint16_t reg = build_register(enable, mode, speed);
    printf("%u", reg);
    return 0;
}
