Webinar: Basics of running NFC and RFID on your Raspberry Pi - 4/8/2015 9:00AM CDT (America/Chicago)

elau
elau over 10 years ago

Join the webinar and learn about the basics of NFC, modes of operation, communication protocols and the new scenarios that the technology opens in the contactless applications domain. The second half of the webinar will be used to demonstrate use cases that can be realized with the expansion board for the Raspberry Pi.

    Since the board is designed for the Raspberry Pi, I'm assuming that the board doesn't have the pull-up resistors (they're on the Pi).  If we were to use the board with a different controller that didn't have the resistors, we'd have to add them (possibly a level converter too).  Anyone have any recommended values for the resistors?

    Not sure which one you mean.

    Reset pin and I2C do have pull up in place. For SPI it's not needed.

    IRQ pin does not have one in place.

    But most MCUs have built in pull-up and pull-down resistors.

    That's good to know.  I'd asked about the resistors because I've been working with Arduino boards on the Raspberry Pi.  Arduinos don't have the resistors as they're normally place on the boards.  In some cases, it's not a problem.  In others, the I2C interface won't function.  Thanks in any case.
