This works great! However, how do I make it so that I can add keys without reprogramming to chip? How can I expand the array within the program? Or is this something better suited with another method? ...

Thanks for the quick reply! This helps. I will take a look at it and try something out!
Thanks again!

Hi all,
I am working on an RFID reader module using a PIC16F688. I have the chip reading the serial data correctly and it can correctly identify a key. The only problem is that currently I have only ...

Hi all,
So I got my PIC16F688 talking to my computer via serial port! Yay!! For a test I have made a simple program to turn a led on and off at 500ms intervals. Depending on where I put the printf st ...

Wow thanks so much guys!
This is another reason I want to try to stick with CCS vs go towards Arduino.
CCS has such a great database of information, especially on this forum! Arduino definitely ha ...

Hi there,
I was wondering if there are any drivers or methods to efficiently create a software serial on a PIC similar to the one the Arduino is capable of:

Thanks for the tip Jerson! I got the lcd to display each set of data stored in the array for string. The first bit is in fact a 10 (which corresponds to a \n]). The last bit is a 0. This is because of ...

I tried that and it actually just prints the code on the top line first, then the second time around and subsequent times it keeps displaying on the bottom. I'm thinking there is a \n being read in. ...

Thanks so much for the help ckielstra! I tried the code and it works! However, the \n (0x0A) carried in by the first bit is causing the display output to be on a new line! I have been trying to throw ...

This extra "2" is really starting to bother me! Jerson, how do you suggest I get rid of the 0X0A? How big should my string length char array be if the string is only meant to be 10 useful ch ...

I've added ERRORS to the RS232 and it seems to have solved the problem of the lockup! Thanks!

Now the problem is: the card ID is: 220056CDD6 ... which is 10 digits. Perfect.

However on the disp ...

Thanks guys! Right now I don't really have the means to connect to pc. My Max232 chips are coming in, and I don't have my serial to usb. I am pretty sure that the hang up is in the get_String. So mayb ...

yes I am sure. I think the get_string() command is the hang up. For some reason it only likes to go through once! I've tested various parts of the code using my lcd and a debugger. Is there some sort ...

Hi all,
so I have successfully read an RFID tag with a PIC. Only problem is that it only reads the string from the RFID reader once. I have a loop set up that would make it read over and over again. ...

Hi all,
I want to create a custom RFID tag system. I am looking at the parallax rfid reader. It sends a signal via RS232 serial ASCII string to the pic. I am fairly new to programming with PICs and C ...
