MTX- 5, New P8X32A Product in Development - Updated

Batang

We are an OEM electronics & software design and manufacturing company in Malaysia.

We have in our line of OEM products, devices for vehicle location systems. I have decided to do a design based upon the P8X32A to add to our range.

Basic specs: Supply Voltage 7 to 33 volts DC, 20 Channel GPS Receiver, Quad Band GSM Modem, 64K EEPROM, 32K SPI RAM as well as the usual inputs and outputs.

Added Battery Management chip for internal lithium battery pack.

Included here are some images rendered from our CAD system as well as a client program that can be used to see the prototype unit in action (See the ReadMe.txt file in the zip). Any questions that relate to the client program PM me so as not to get off track here.

Although this unit will be supplied through our OEM business if there is any interest we may make it available in small quantities should anyone wish to play with such devices.

Batang,

We are developing some objects that may be of aid to you.

One object reads the GPS $GPRMC string and parses it, returning time and location in 32-bit angles. It also performs bearing and distance computations from other points.

The other object talks to GSM modems to send and receive SMS messages.

Caution: If you are going to use a 20MHz crystal with the Propeller, don't use the PLL, because the Propeller will try to generate 320MHz internally, which might be in excess of its capability. If you run the Propeller directly off the crystal at 20MHz, though, that would be fine.

Hi Chip,

Thanks for the info about the objects, these we have already written, although I will have a look at your GPS object.

The GSM object uses UDP over GPRS with a fall back to SMS.

Ignore the crystal markings (20MHz) as it was the only CAD Model I had in my library.

Cheers.

Very nice concept! Thanks for sharing.

I'm interested if it's in my price range for a "new toy" to add to my collection, I'd also be interested to see the applications a product like this would have; the "powers that be" where I work have been meeting with reps from different equipment providers to possible replace the RTUs that connect to our SCADA via radio through a Lantronix, to -possibly- something that uses SMS. (Hey, state of the art... 20 years ago when it was put in.)

Upon receiving feedback from Parallax the P8X32A package has been changed to QFP.

Also added Battery Management IC for internal lithium battery pack.
