no guarda forse mi sono sbagliato ad esprimermi .. non è che deve andare in conflitto è che sono io che non riesco ad unire i due codici insieme ossia quello dell'rfid e quello del servo..
il codice dell'rfid è questo
#include <MFRC522.h>
#include <SPI.h>
#define SAD 10
#define RST 5
MFRC522 nfc(SAD, RST);
void setup() {
SPI.begin();
// Read a fast as possible. There is a limit for how long we are
// allowed to read from the tags.
Serial.begin(115200);
Serial.println("Looking for MFRC522.");
nfc.begin();
// Get the firmware version of the RFID chip
byte version = nfc.getFirmwareVersion();
if (! version) {
Serial.print("Didn't find MFRC522 board.");
while(1); //halt
}
Serial.print("Found chip MFRC522 ");
Serial.print("Firmware ver. 0x");
Serial.print(version, HEX);
Serial.println(".");
}
byte keyA[6] = {0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, };
byte keyB[6] = {0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, };
void loop() {
byte status;
byte data[MAX_LEN];
byte serial[5];
int i, j, pos;
// Send a general request out into the aether. If there is a tag in
// the area it will respond and the status will be MI_OK.
status = nfc.requestTag(MF1_REQIDL, data);
if (status == MI_OK) {
Serial.println("Tag detected.");
Serial.print("Type: ");
Serial.print(data[0], HEX);
Serial.print(", ");
Serial.println(data[1], HEX);
// calculate the anti-collision value for the currently detected
// tag and write the serial into the data array.
status = nfc.antiCollision(data);
memcpy(serial, data, 5);
Serial.println("The serial nb of the tag is:");
for (i = 0; i < 3; i++) {
Serial.print(serial[i], HEX);
Serial.print(", ");
}
Serial.println(serial[3], HEX);
// Select the tag that we want to talk to. If we don't do this the
// chip does not know which tag it should talk if there should be
// any other tags in the area..
nfc.selectTag(serial);
// Assuming that there are only 64 blocks of memory in this chip.
for (i = 0; i < 64; i++) {
// Try to authenticate each block first with the A key.
status = nfc.authenticate(MF1_AUTHENT1A, i, keyA, serial);
if (status == MI_OK) {
Serial.print("Authenticated block nb. 0x");
Serial.print(i, HEX);
Serial.println(" with key A.");
// Reading block i from the tag into data.
status = nfc.readFromTag(i, data);
if (status == MI_OK) {
// If there was no error when reading; print all the hex
// values in the data.
for (j = 0; j < 15; j++) {
Serial.print(data[j], HEX);
Serial.print(", ");
}
Serial.println(data[15], HEX);
} else {
Serial.println("Read failed.");
}
} else {
// If we could not authenticate with the A key, we will try
// the B key.
status = nfc.authenticate(MF1_AUTHENT1B, i, keyB, serial);
if (status == MI_OK) {
Serial.print("Authenticated block nb. 0x");
Serial.print(i, HEX);
Serial.println(" with key B.");
status = nfc.readFromTag(i, data);
if (status == MI_OK) {
for (j = 0; j < 15; j++) {
Serial.print(data[j], HEX);
Serial.print(", ");
}
Serial.println(data[15], HEX);
} else {
Serial.println("Read failed.");
}
} else {
Serial.print("Access denied at block nb. 0x");
Serial.println(i, HEX);
}
}
}
// Stop the tag and get ready for reading a new tag.
nfc.haltTag();
}
delay(2000);
}
mentre quello del servo è questo
// Sweep
// by BARRAGAN <http://barraganstudio.com>
// This example code is in the public domain.
#include <Servo.h>
Servo myservo; // create servo object to control a servo
// a maximum of eight servo objects can be created
int pos = 0; // variable to store the servo position
void setup()
{
myservo.attach(9); // attaches the servo on pin 9 to the servo object
}
void loop()
{
for(pos = 0; pos < 180; pos += 1) // goes from 0 degrees to 180 degrees
{ // in steps of 1 degree
myservo.write(pos); // tell servo to go to position in variable 'pos'
delay(15); // waits 15ms for the servo to reach the position
}
for(pos = 180; pos>=1; pos-=1) // goes from 180 degrees to 0 degrees
{
myservo.write(pos); // tell servo to go to position in variable 'pos'
delay(15); // waits 15ms for the servo to reach the position
}
}
ora come li unisco questi due codici ?
