DL533N NFC RFID Reader Testing Tool

Basic Functions Control testing Script for PN533-based Reader

DL533N Reader Testing Tool is a simple software script for PN533-based DL533N NFC Reader basic testing. The script provides an example of using GPIO pins for LEDs and buzzer control. Since DL533N NFC Reader is based on NXP’s PN533 chip,  to run this testing tool script, you need to install a LibNFC first.

Software manual

1. DL533N Reader Testing Tool – Getting Started

Download: DL533N

To implement the DL533N Reader Testing Tool, you need to download and install the LibNFC first. Download and extract the LibNFC package, and start the installation following the provided instructions.

The DL533N testing script requires the libNFC pn53x-tamashell executable.

For more details on the of register manipulation, search for the PN533 chip technical documentation on the NXP Semiconductors official website.

2. DL533N Reader Testing Tool – Script Installation

The DL533N Reader Testing Tool requires no installation
Simply download and extract the DL533N script pack.

After you have successfully installed LibNFC as described in the previous step, run pn53x-tamashell as follows:

./pn53x-tamashell testGPIO_dl533_short

Notice: The testGPIO_dl533_short  is the script executable filename.

2. DL533N Reader Testing Tool – Run The Script

The script is commented so you can interactively follow the events. After each performed step, the script is paused for 500 ms.

The testing is performed as follows:

1. GET_FIRMWARE command issue
2. Get status registers P3CFGA P3CFGB of GPIO pin P3
3. Write Register of P3 to zero
4. Get status registers P7CFGA P7CFGB of GPIO pin P7
5. Write Register of P3 to zero
6. Get status register 6106 which is needed to obtain control of P34 GPIO
7. Turn on the Green LED by issuing WriteRegister P7 with value 0x01
8. Turn off the Green LED by issuing WriteRegister P7 with value 0x00
9. Turn on Red LED by issuing WriteRegister P3 with value 0x20 – bit 5 GPIO P35 up
10. Turn off Green LED by issuing WriteRegister P3 with value 0x00 – bit 5 GPIO P35 down
11. Play sound on Buzzer by issuing WriteRegister P3 with value 0x10 – bit 4 GPIO P34 up
12. Turn off sound on Buzzer by issuing WriteRegister P3 with value 0x00 – bit 4 GPIO P34 up
13. Turn on both LEDs and play sound
14. Change the state of GPIO pins from QUASI BI-DIRECTIONAL (default) to PUSH-PULL OUTPUT
15. Reset registers to default values.

This manual presents the simple testing script for LibNFC based DL533N Series readers.
