Thread: Bitwise operators

Hi, could someone explain me how the if statement works in the snippet below? Despite the fact that I know how bitwise works I cannot understand when the

Code:

 channel & (1 << i)

will be TRUE and when will be FALSE.

Code:

void selectMuxPin(int channel) {  
for (int i = 0; i < MUX_CTRL_CHA; i++) {
    
    if (channel & (1 << i)) {
      nrf_gpio_pin_set(ctrlPins[i]);
      }else {
      nrf_gpio_pin_clear(ctrlPins[i]);
    }
  }
}
