Помогите плиз взят пример:
Мастер прием:
#include <Wire.h>
int result1 = 2;
int result2 = 2;
int result3 = 2;
int result4 = 2;
void setup() {
Wire.begin(); // join i2c bus (address optional for master)
Serial.begin(9600); // start serial for output
}
void loop() {
Wire.requestFrom(8, 8); // request 6 bytes from slave device #8
while (Wire.available()) { // slave may send less than requested
result1 = Wire.read ();
result1 <<= 8;
result1 |= Wire.read ();
result2 = Wire.read ();
result2 <<= 8;
result2 |= Wire.read ();
result3 = Wire.read ();
result3 <<= 8;
result3 |= Wire.read ();
result4 = Wire.read ();
result4 <<= 8;
result4 |= Wire.read ();
Serial.print(result1);Serial.print(" ");Serial.print(result2);Serial.print(" ");Serial.print(result3);Serial.print(" ");Serial.println(result4);
}
delay(500);
}
Слейв отдача:
#include <Wire.h>
int value1 = -12350; // ie. 0x04 0xD2
int value2 = -1350;
int value3 = 2350;
int value4 = 12350;
void setup() {
Wire.begin(8); // join i2c bus with address #8
Wire.onRequest(requestEvent); // register event
}
void loop() {
delay(100);
value1 = value1 + 1 ;
value2 = value2 + 1 ;
value3 = value3 + 1 ;
value4 = value4 + 1 ;
}
// function that executes whenever data is requested by master
// this function is registered as an event, see setup()
void requestEvent() {
Wire.write (highByte (value1));
Wire.write (lowByte (value1));
Wire.write (highByte (value2));
Wire.write (lowByte (value2));
Wire.write (highByte (value3));
Wire.write (lowByte (value3));
Wire.write (highByte (value4));
Wire.write (lowByte (value4));
// as expected by master
}
Переделал отдачу
for (int i = 0; i < 8; i++) {
Wire.write (highByte (myInts[i]));
Wire.write (lowByte (myInts[i]));
}
}
Прием:
void WareReadSlave() { // request 8 bytes from slave device #8
Wire.requestFrom(8, 8);
while (Wire.available()) { // slave may send less than requested
myInts1 = Wire.read ();
myInts1 <<= 8;
myInts1 |= Wire.read ();
myInts2 = Wire.read ();
myInts2 <<= 8;
myInts2 |= Wire.read ();
myInts3 = Wire.read ();
myInts3 <<= 8;
myInts3 |= Wire.read ();
myInts4 = Wire.read ();
myInts4 <<= 8;
myInts4 |= Wire.read ();
myInts5 = Wire.read ();
myInts5 <<= 8;
myInts5 |= Wire.read ();
myInts6 = Wire.read ();
myInts6 <<= 8;
myInts6 |= Wire.read ();
myInts7 = Wire.read ();
myInts7 <<= 8;
myInts7 |= Wire.read ();
myInts8 = Wire.read ();
myInts8 <<= 8;
myInts8 |= Wire.read ();
}
}
В последних четырех значениях билиберда.
Как изменить код. Подскажите?
