RaspberryPi, Pi Face

[folk]

Hello !
So actually i have a raspberry pi and a piFace in order to control a motor using RFID. I use a grove RFID http://www.seeedstudio.com/wiki/Grove_- ... FID_Reader it needs 5 volts
but the R-Pi ports are not available i don't know how i should connect that on my Raspberry Pi !
To sum up i have something like this : http://technology-guerilla.de/wp-conten ... erface.png

and i want to add this : http://www.seeedstudio.com/wiki/Grove_- ... FID_Reader
I don't know where are the serial inputs or the equivalent of the "analog comparator input" on the piFace !

Thank you !

Hello

Your
PiFace Digital

PiFace Digital allows you to connect things like switches, lights and motors so your Raspberry Pi becomes aware of, and can influence the world around it.

have no UART.

Maybe you will study

Rio connect AT the UART

Hi Alex,
So that's impossible to connect Grove RFID on a PiFace ?
should i use a UART converter ? Hm... I'm disappointed because i've just bought a piFace card, I have a question can i control a motor and use RFID with these components :

-Embedded Pi
- Module Grove Base Shield SLD12148P : http://www.gotronic.fr/art-module-grove ... -19068.htm
- RFID Grove 125 kHz SEN11425P : http://www.gotronic.fr/art-lecteur-rfid ... -19038.htm
-RaspberryPi

all with python ? I think it's better to use a Arduino Shield for the RFID ! Do you know how should i connect it ?
Thanks for all ! Are you French ?

Hi Folk,

If this is the RFID reader which I bought from : http://www.seeedstudio.com/depot/125Khz ... Path=19_24, then I've created a guide to use it with the Raspberry Pi at:

I posted the circuits and assembly on my website:
http://www.pi-lock.com/participate/assemble

The code and installation can be found on:
http://www.pi-lock.com/participate/install

My overall project is much more complex than using a RFID reader, but take a look at the circuit to connect the RFID shield to your Pi.

You will have to install the python libraries first, then modify my python code a bit. You will find the python code to read the the RFID tags in the file: readRFID.py, at:

https://github.com/pi-lock/pi/blob/master/readRFID.py

If you need further explanation let me know

Hi and thanks for your help!
So, actually i just have an embedded pi, the Grove RFID (not the same as yours), a piFace a motor and a raspberry pi ! And the Base shield you can found at http://www.robotshop.com/en/i-o-base-sh ... duino.html
I don't know how to control my Rfid sensor with Raspberry pi, i know that it can be control with an arduino shield !
So do you know how can i connect it on any of these components ? and how ?
Thanks !!

And why you don't use the UART port to connect the RFID on the Raspberry pi ?
