bitSet()
설명
숫자 변수의 한 비트를 1로 설정합니다.
문법
bitSet(x, n)
매개변수
- x: 비트를 설정할 숫자 변수
- n: 설정할 비트의 위치, LSB(맨 오른쪽 비트)가 0, 왼쪽으로 갈수록 1씩 증가
반환값
- 없음
예제 코드
Demonstrates the use of bitSet() by printing the value of a variable to the Serial Monitor before and after the use of bitSet().
void setup() {
Serial.begin(9600);
byte x = 0b10000000; // the 0b prefix indicates a binary constant
Serial.print("BEFORE: ");
Serial.println(x, BIN); // 10000000
bitSet(x, 2); // write 1 to the third bit
Serial.print("AFTER: ");
Serial.println(x, BIN); // 10000100
}
void loop() {}
The result in Serial Monitor:
COM6
BEFORE: 10000000
AFTER: 10000100
