Raspberry  plus 2 cartes PiFace

Former Member
Former Member
21 Oct 2013

Bonjour,

J'acheté 1 RaspRack et 2 cartes Piface,

le PiRack est fait pour ajouter plusieurs cartes Piface (elles sont adressables en hardware de 0 à 3 par des cavaliers).

Aucune notice ou exemple, pour commenter la partie software !

J'ai donc installé les deux cartes l'une en adresse 0 l'autre en adresse 1.

Ma question :

- Comment adresser une commande  à la deuxième carte Piface ?
- Comment lire les entrées de la deuxième carte Piface ?

Un exemple simple sous Python serait le bien venu.

Idem pour l'interface Piface-emulator il ne connais que la carte 0.

D'avance merci de votre réponse.
Cordialement Joël.

 

Hello,
I bought one RaspRack and 2 cards Piface. The PiRack is made to add more Piface cards (they are addressable hardware 0-3 by jumpers).
Any record or example, to comment on the software part!
So I installed both cards, the first address in 00, the second address 01.
My question:
- How to send a command to the second Piface card?
- How to read the entries in the second Piface card?
A simple example in Python would be welcome.
Ditto for the interface Piface-emulator, it just recognize the card 0.
Thank you in advance for your answer.
Sincerely Joel.

    1. You can send the command using

    digital_write(pin_num, value, hardware_addr=0) i.e pfio.digital_write(0,1,1);

    Turn Led 1 ON on board number 2

    2. You can read the state of an Input

    digital_read(pin_num, hardware_addr=0) i.e pfio.digital_read(0,1);

    Read Input pin 1 on board number 2

    See here for Examples http://piface.github.io/pifacedigitalio/example.html

    Hope that helps image
