ccs rfid code
Hello,
I will describe how it works and what it consists of, in short lines.
Parts and a little hardware specification.
The system consists of pcb (printed circuit board) with all electronics on it, including switching relay, rfid ID-12 reader, power stabilizer (+5V), only a few least significant parts beside and microcontroller with adequate flash program AND/OR built-in antenna on the pcb itself or external antenna, for 125 khz. External antenna can be up to 70cm away from the unit (pcb). There are two switches to be mounted on housing as well as 3 (three) LED diodes (reg, green and yellow) for indication of state of the system in any moment, any time.
Unit operation.
The operation is in photos and .avi animations. I will just write some options supported and realised:
1. Card learning 1-6 (6 max.)
2. Card deleting (all - memory format)
3. 2 (two) modes of operation (with 1 jumper)
3a. Pulse mode with custom delay choice (with 4 jumpers)
3b. Toggle mode
4. If all cards lost - format system (restoring it to factory settings with 0 cards learned). Formating starts with holding both buttons and powering-up the device, OR, holding one button and unlocking the "lock" with a card, if you have not lost all of them.
I think that this is all for now. In animations you will see learning pocedure, working (toggle mode) and working (pulse mode) with a few different delays for LOCKED/UNLOCKED state in pulse mode.

That's it in a few words.
