PropScope with Android?

kane

Hi,

I recently bought a PropScope from Parallax, it is a nice device
and works well on my WinXP laptop.

I'd to use to take some simple measurements with my G1 Android phone.
I do not need a fancy GUI just a way to stream values from CH 1/2.

Has anyone used Android to talk to the PropScope? I've taken
a quick look at the document:

PropScope Protocol
V0.8 February 2010

and have some technical questions.

For example, how do I download the firmware to
the device from Android? The protocol doc says:

On launch, the UI uses the Propellent library
available from Parallax to detect and reset a
Propeller whose USB name is “PropScope”.
(It uses "-*,+PropScope" as a Serial Search
Rule). Once reset, it loads “propscope.binary”
from the propscope/firmware directory to
the Propeller RAM and runs it.

What is the format of the firmware file?

Thanks,

Pat Kane

Hi Pat,
Glad you like the PropScope.
The firmware binary is in the Propeller format. If you just need Ch1 and Ch2 measurements the easiest way is to write your own firmware. To do it right you would take advantage of the calibration data written into EEPROM and allow setting of the prescaler and ac/dc coupling. Then, write that data out over serial.
