bitRead()
설명
숫자의 한 비트를 읽습니다.
문법
bitRead(x, n)
매개변수
- x: 읽을 숫자
- n: 읽을 비트, LSB(맨 오른쪽 비트)가 0, 왼쪽으로 갈수록 1씩 증가
반환값
- 비트의 값 (0 또는 1).
예제 코드
void setup() {
Serial.begin(9600);
byte x = 0b10000101; // the 0b prefix indicates a binary constant
Serial.println(x, BIN); // 10000101
for (int i = 0; i < 8; i++)
Serial.print(bitRead(x, i)); // print bits one by one
}
void loop() {}
The result in Serial Monitor:
8
Serial.println("Hello World!");
