HydraNFC Shield v1

Description

This shield is mainly used with HydraBus (with full support in hydrafw) but can also be used with other MCU.
Features of the HydraNFC Shield v1 board:
* Autonomous mode with 4 User buttons and 4 User LEDs.* Use HydraBus microSD card to save or load data (up to 32GB).
* Use Texas Instrument TRF7970A NFC chipset.
* External NFC antenna can read Mifare-One at up to 8cm (tested with 20cm cable with U.FL and SMA connector).
* Read / Display / Save Mifare Ultra Light tag data* Emulate Mifare Ultra Light tag (7Bytes UID and 64bytes data support) HydraNFC is fully supported by open source HydraBus firmware hydrafw: https://github.com/bvernoux/hydrafw

Details

Features of the HydraNFC embedded firmware HydraFW:

Virtual Serial Port access through microUSB with VT100 terminal/shell (compatible with any hardware supporting USB Virtual Serial port).
Basic UID read for Vicinity/ISO15693 (through shell command).
Basic UID read for ISO14443A tags (through shell command).
- Scan mode display 4Bytes or 7Bytes UID for ISO14443A tags (include also Mifare...).
Sniffer mode in autonomous/stand-alone mode for ISO14443A including both PICC and PCD with data logged to microSD card (tested with success with Mifare Classic, Ultralight and shall work with any other ISO14443A NFC tags @106KHz).
- Sniffer can be launched also with "sniff" command:
  - When stopped (K4 is pressed & released):
    - All sniffed data are displayed in console
    - If a MicroSD is present, it will automatically save the trace in a unique txt file
- Advanced sniffer "sniff-debug" command same as "sniff " command but add:
  - After each 8bits/byte the parity (ASCII char "0" or "1" + space)
  - End Of Frame Timestamp (unit is 1/168MHz) + RSSI
Tag Emulation UID ISO14443A (Mifare 1K)

HydraFW v0.5 Beta released with support of HydraNFC/TRF7970A
http://hydrabus.com/2015/02/11/hydrafw-v0-5-beta-released/
Also a tutorial as been added to understand/learn how work TRF7970A NFC chipset
See https://github.com/bvernoux/hydrafw/wiki/HydraFW-HydraNFC-TRF7970A-Tutorial
The tutorial details how to:
- Initialize GPIO & SPI to communicate with TRF7970A/HydraNFC
- Initialize & read ISO15693/Vicinity Tag
- Initialize & read ISO14443A/Mifare Tag
- Use TRF7970A commands (SLOS743K – August 2011 – revised April 2014)
HydraFW v0.4 Beta released
Benjamin Vernoux • 01/04/2015 at 19:08 • 0 comments

Major improvement/refactoring towards terminal/syntax using tokenline (instead of microrl) thanks to Bert Vermeulen (biot) for that amazing piece of software and all the work on this project.
New commands for HydraNFC to scan Mifare & Vicinity Tags with a defined period and also one shot or in continuous mode.

HydraFW official firmware 0.1Beta released for HydraBus/HydraNFC
Benjamin Vernoux • 09/21/2014 at 15:03 • 0 comments

HydraFW is a native C (and asm) open source firmware for HydraBus board with support of HydraNFC Shield.
This version is basic and mainly for HydraNFC users waiting sniffer mode for NFC ISO/IEC 14443 Identification cards.
The firmware can be installed without recompilation (dfu binary included) by following the 7 steps to flash their HydraBus board.
It is available on github:
https://github.com/bvernoux/hydrafw
HydraNFC board, BOM and doc available on github
Benjamin Vernoux • 09/12/2014 at 16:25 • 0 comments

HydraNFC GitHub Repository:
HydraNFC_1_1_Rev1: HydraNFC Shield Schematic and Board CadSoft Eagle 6.x
HydraNFC_Antenna_1_0_Rev0: HydraNFC Antenna Schematic and Board CadSoft Eagle 6.x
All those boards and BOM are now available on github:
https://github.com/bvernoux/hydranfc/tree/master/hardware
HydraNFC Firmware (for HydraBus) will be soon available
HydraNFC Firmware is coming
Benjamin Vernoux • 09/03/2014 at 11:05 • 0 comments

HydraNFC Hardware:
Schematic in PDF and CADSOFT Eagle 6.x design (CC BY NC) will be available (HydraNFC github) at same time as HydraBus will be in shop.
HydraNFC Firmware (requires HydraBus) with VT100 and Autonomous mode (requires only power through USB):
V0.1 Beta will be available (HydraNFC github) in about 2weeks on github, as I'm cleaning stuff and updating autonomous mode.

Bonjour Mathieu,

Désolé mais il n'existe a ma connaissance aucune librairie trf7970a pour du 8bit
hormis les exemples de TI sur MSP430 qui est 16bits.
Je pense que l'utilisation du TRF7970A sur autre chose qu'un MCU 32bits > 72MHz
a très peu d’intérêt sauf pour lire un UID ou faire des choses très simples
(dans ce cas je conseil un chipset NXP PN532 qui est beaucoup plus haut niveau).
Tu peux toujours regarder le driver TRF7970A du firmware (hydrafw) pour
HydraBus ici:
https://github.com/bvernoux/hydrafw/blob/master/trf7970a/

Hello!

Voyant le .fr, je me permets de t'écrire en francais.
Je viens de réaliser une petite board avec un ATMega32U4 et un TRF7970A. Etant donné que tu as l'air bien avancé avec ce chip, j'aurais voulu savoir s'il y avait une libraire 8 bits que je pourrais utiliser? Au pire je pourrais utiliser celles fournies par TI... mais quelque chose me dit que cela va être compliqué pour pas grand chose...

Merci!
