嗨我想通過I2C將arduino pro mini連接到我的AtTiny85。AtTiny85和Arduino之間的簡單通信(I2C)
arduino應該告訴attiny打開或關閉LED。 arduino設法切換我attiny上的LED,但它永遠不會熄滅。
我沒有任何線索爲什麼?
這裏是我的主,從代碼:
MASTER:
#include <Wire.h>
#define device (1)
void setup() {
// put your setup code here, to run once:
Wire.begin();
}
void loop() {
// put your main code here, to run repeatedly:
Wire.beginTransmission(device);
Wire.write(1);
Wire.endTransmission();
delay(2000);
Wire.write(0);
Wire.endTransmission();
delay(2000);
}
SLAVE:
#include <TinyWireS.h>
#include <usiTwiSlave.h>
#define output (4)
#define I2C_SLAVE_ADDR (1)
void setup() {
// put your setup code here, to run once:
TinyWireS.begin(I2C_SLAVE_ADDR);
pinMode(output, OUTPUT);
}
volatile byte msg = 0;
void loop() {
if(TinyWireS.available())
msg = TinyWireS.receive();
if(msg == 1)
digitalWrite(output, HIGH);
else if(msg == 0)
digitalWrite(output, LOW);
else
msg = 0;
}
