Greetings,

I just signed up for this mailing list and am starting
out with the BasicX. I have completed a couple useful
projects with the Basic Stamp (BS2) and just finished
a PIC project with CCS C compiler.

Among my projects, I am constructing a mobile robot
and would like to build a remote control weather station.
Also, I build accessories for my amateur radio hobby.
See my web page: http://www.qsl.net/k7on/

I am starting out with the BasicX starter kit (not the BS2X).
Any helpful suggestions appreciated.

Thanks, Brian

Hi all-
I'm a newbie from the beam camp and I just got a basicx and i was
wondering how do you use the interrupt pin to do hardware interrupts.

Thanks in advance,
David

The way to get access to hardware interrupts is to call WaitForInterrupt,
which halts the program (or calling task, if you're doing multitasking)
until a hardware interrupt occurs.

Look in the app notes directory for the document and example program called
CountingPulses. This has example code that calls WaitForInterrupt.

Hello, My name is Don Lewis. I have recently purchased
a BX-24 through phanderson.com. His service was very good.
It was quite a buy in my opinion. This product is super easy to
use. I will be lurking to learn as i grow accustomed to utilizing
the BX-24. I have already searched your messages for several topics
and have picked up a great deal of info.
My project will include the BX-24, LCD+ and the jrkerr Pic_servo
chipset. I am designing, with some ideas from others, a observatory
Dome controller that will follow a telescope as it slews and
tracks.
Thank you,
Don



Don,

The bx-24 should do nicely for your project. It will do the RA-DEC
to AZ-EL conversions easily. Short term time stability will be good
enough.

How are you going to interface to the dome motors?

What temperature range will it be operating in?

Andy

Have you already worked on a project like this?

I can grab RA and DEC values from my mount. I am converseing
with the mounts software designer to get more info like
OTA East or West of pier, Local Sidereal Time and Azimuth ( features
not yet in place). > Short term time stability will be good

I thought to unload some work from the BX-24, pwm and counting.

The Pic-servo chip will interface to a mosfet h-bridge with a little
logic to interface the pic's enable, direction, brake and motor sense
pins. It will pwm the mosfets. I still have a high current relay
to switch between Dome rotation and shutter motors.
The Pic-Enc will read an encoder for fwd/rev positioning info.
I don't yet know how this combination will work out in my plans.
I am also interested in the ICON H-Bridge as a motor drive solution.

I live in central Arkansas. Our lows don't go below the 20's
and only for short durations. Summertime runs about 100 degree F. >
