VTI SCP1000 30-120 kPa Pressure Sensor

I noticed Parallax has added the scp1000 to its wares, but after looking at the docs, it looks like this is more for the prop than the BS2. At least the source code posted is for the prop. The docs do mention something about BS2 ops but a voltage translator is required. I'm not half bad with TTL but never worked with SPI before, so here's my questions.

1. Is source code available for the BS2
2. What would I need for the voltage translator
3. Where can I find a tutorial for learning SPI
4. If the scp1000 isn't BS2 friendly, I'm looking at the HP03d pressure sensor as an alternitive, using I2C. http://www.futurlec.com/Pressure_Sensors.shtml· Does anyone have experience with this sensor and the BS2, If so I'd love to see some source code.

Thanks...Hermie

    Hello,

    Our goal is to have BS2 code for the SCP1000 by next week. First an easy schematic needs to be devised that the average customer can implement to connect the device without damaging sensor. Once that is settled the code will be released as well. Please check back next week for updated code and documentation for both the Propeller and BASIC Stamp modules. Take care.

    No problem...I am just sorry I couldn't get them to you all sooner. This next week will be spent getting the code that is lacking for a few things. I have cleared that time for doing this. Thanks for the feedback.

    What we ended up doing was using the 74LVC244A for the interface.· It turns out someone had already written some code for the sensor using the BASIC Stamp 2.

    Hello Chris!

    I'm a newbee to basic stamp (but and old guy - 62). I have the basic stamp usb kit as well as the VTI SCP1000 pressure sensor. I bought a 3.3 to 5v converter from Kronosrobotics. Now it looks like I need a 74LVC244A to get it all to work. Have I missed something? This is my first project on the basic stamp so any advice on how to hook it up and start measuring pressure/temperature would be much appreciated. I am a big believer in not reinventing wheels, so if there are some sample programs, pictures, diagrams etc., that would be fine. I have the "maxentropy" article from the net, but I'm not sure what he means by the "professional development board" - I think it is just the breadboard that comes with the basic stamp kit ???

    In the words of my generation, "Help me Mr. Wizard...."

    Ha!

    Thanks,

    Walt

    I have seen the code, but I don not see the pin assignment to be used and the connections involving the level translators. This information would be very valuable.

    Thanks
