Error: Could not find packages

ThaEagle

Hi. I'm newable to Javelin, and I have 4 weeks left before my project has to be ready for the examination.

I had to create the following folder to remopve this error, but I'm pretty shure that I need some files as well.
c:\programfiler\Parallax inc\Javelin\ Stamp\IDE\Projects/stamp/peripheral/sensor/compass/HM55B/ is empty.
Is there any files that I need to download to get my kompass working propertly? And where do I get theese files?
I need packages for: Int32, Compass HM55B, and receiving Text signals from 5V com-port.(Using GPS EM406a from GlobalSat).

My project is to create a GPS-controlled RC-car with realtime programming. And I need this project to be up and running to get my Bachelor degree.

I will be gratefull for any ideas that helps.

Attached are the two classes I have in that folder.
Actually, the path is
c:\program files\parallax inc\javelin stamp ide\lib\stamp\peripheral\sensor\compass\HM55B

Ah.. Ehe..
I belived that theese files was the program to be uploaded to the Javelin controller.
But now I understand how to use them.

Thank you for your quick replay.

Here you will find the Int32 class.

I do not know about a EM406a gps class.
There is a class for the Parallax GPS module.

Receiving serial signals (TTL=5V) is done by using
the Uart class.

Int32, is that the same as IntegerMath, but with new name only?
Got an compiling error that refered to IntegerMath.

Again, Thanks!

Edit:
It seems to that I need the IntegerMath class as well, But I can only find Int32 while searching for it.
Hopefully this will be the last claas I need for this Compass

IntegerMath package is different from Int32 package
but both packages go into folder ...\lib\stamp\math

I attached the IntegerMath class for your convenience.
Most classes can also be found at the JavelinCode yahoogroup:
http://tech.groups.yahoo.com/group/JavelinCode/files/Javelin%20Stamp%20IDE/
Just navigate to lib/stamp/math to find all available math packages.

Thank you. Now I got a complete Compass project, and I know where to find packages.
Just some bugging left on the compass then. Cp1. would not poll.

Peter Verkaik

Be sure to connect the compass GND to the javelin GND (Vss),
otherwise the datapin, clockpin and enablepin will not be
steady.

Done.
But I still got nothing.
It seems that the >>m_status = CPU.shiftIn(m_DinDout, m_Clk, 4, CPU.POST_CLOCK_MSB );<< always want to end up with the value 0.

This is in the HM55B.java
I added a >>System.out.println(m_status);<< right after the >>m_status = CPU.shiftIn(m_DinDout, m_Clk, 4, CPU.POST_CLOCK_MSB );<<
