teding:
Maybe this tutorial can help you futher,
http://www.tigoe.net/pcomp/code/PHP/347/
I did build my code around this and works great.
I appreciate the link, but Tom approaches this a little differently since he is reading and writing to EEPROM.
However, I figured it out this morning by adding one extra loop to check my other Tag ID's. Now it works.
Here is the code for the loop:
for (int n=0; n<ARR_LEN; n++){
if(memcmp(master, target_tag[n], TAG_LEN) == 0 ) //Compares two bytes of TAG_LEN, if they are a match, the argument will be 0, thus 0 == 0
{
Serial.println("This Card is a Match!");
}
}
Thanks.
