Thread: Stamp --> Propeller

  1. #1

    Default Stamp --> Propeller

    I'm working on a project to transmit data across wireless. My only issue is that the transmitter is using BASIC stamp while the receiver is using a Propeller board. Any suggections? The stamp is from a BoE-bot kit and the propeller is part of the Spinneret

    Range and type of data?

    i'll be using 8 bytes using string data

    The questions Leon asked and. . .

    Do you already have transceivers? Many (most?) will work fine with either the Prop or the Basic Stamp.

    What baud rate do you need/want?

    How far do you need/want to transmit? Through walls, etc.?

    I'll be using 8 bytes in string form
    I have the discontinued 433MHz receiver and transmitter from parallax
    I'm looking at about a 9600 baud rate
    The transmission is through open air, so about 100ft would be just fine
    The data is coming from the Ping))) ultrasonic, the tri-axis accelerometer, and the compass module

    just to bring your attention to the matter

    You should be fine. I think there is code to use the 433MHz devices for both the BS and the Prop.

    You will want to decide if you'll send the data as raw values or if you'll convert them to ASCII characters first.

    To answer the underlying question - the fact that you have a Stamp on one side and a Prop on the other makes little difference, except of course to the fact that you have to write your code in two different languages.

    The receiving device cares about the format of the data (raw bytes? ASCII?) and the serial format (Baud/bits/stop bits), but doesn't care at all about what kind of device sent those data. I've sent data from Stamps to Props and vice-versa using both XBee and the standard 433 MHz Parallax transmitters/receivers (pre-transceiver) without any trouble.

    If you want to see how the fundamental serial communications is handled in a simple test between Stamp and Propeller, and see the circuit schematic, photo, and code, by taking a look at some of the posts for the Brain Stem which uses both Propeller I and BASIC Stamp 2 BOE.
