Has somebody got experience with programing arduino or any other microcontroller?
Can i connect arduino into the jornada with pcmcia? Do you know abouth any software for hpc (for example: avr studio)?
Making them talk to each other is not a big problem. Like.. the Jornadas all have a serial port, you'll just need a Converter IC such as the MAX232.
Of course you'd have to write software on the jornada! I don't know if there's a serial terminal program available..
Once a did a trick with my Jornada and some PICs. Using MAX232 and the J728 serial port I stabilished communication from my jornada to PIC using a small firmware I wrote on the PIC. Arduino is a very good idea to implement. But I think that it's a little hard to run the compiler on our small (and low JAVA-enabled) HPC devices. To just communcate (like transfer files, programs or information) between your HPC and Arduino is pretty easy. If you have and Arduino Serial (the one without FTDI Chip and with a serial output) then you are ready to go. But if you have Arduino Duemillanove or other USB version, probably you will have to find FTDI Drivers for WinCE (I don't believe that they exist actually).
But if you want to compile your software on the HPC, you first need to get the Arduino source code and try to run it on a good portable JVM available for you HPC, and cross your fingers (dunno it will run it). Running the entire Arduino IDE is a way more complex task
The arduino IDE is written in Java, but it depends on numerous other non-Java Tools such as avr-gcc, avr-g++ and other avr toolchain tools, aswell as avrdude for uploading programs.
Too bad Rainer Keuchelt doesn't do stuff anymore, otherwise we should poke him and ask to port the avr toolchain..
There's PersonalJava which is Java 1.1 compilant. Meaning you won't be able to run anything new on there, but you can write your own Java apps.
If you want it, send me a pm! I also have a (not tested yet) package that should allow you to use the Serial port with java.

but i have arduino with rs232.
