PBP projects for R/C models

Not a problem Ken, this is definitely the hardest part. And the manual doesn't really pull it all together for me either. Once you have a connection, you almost don't have to worry about those parts again though.

Here is the hex file you need. I have it in a zip file attached. It also has the driver you need. You must install the driver into your computer. Right click the driver, and select install. Then hopefully when you plug the USB cord from the UBW to the computer, you hopefully will see something happen.

We will get it going, or die trying. Hopefully the former.

Thank you scalerobotics!

The .hex file you sent compares exactly to the one I used. At least each displayed using 'notepad' are identical. The .inf file you sent enticed WINDOWS XP PRO into displaying a GUI warning me against installing it as it had not passed the WINDOWS LOGO test! Do you think I should ignore the warning?

I was hoping I would find in my MicroCode Studio Target Processor pull down menu a reference to the PIC32 that we are using. Nope! Do they sell an appropriate BASIC compiler?

No, they do not. I think you are limited to C, assembly, or StickOS with the 32 bit devices. I thought you were going to try StickOS though? If so, you really don't need to learn too much about the chip. StickOS does most of background stuff for you.

AFAIK, no one makes a BASIC compiler for the PIC32 (or any other 32-bit MCU for that matter). Your best bet is to go with C which is pretty the de-facto language (not a lot more difficult to learn/use but far more powerful/flexible/reliable).

In my opinion, C would be a lot harder for the middle school students to learn. C isn't very readable if you ask me.

For one you have to teach them
{why all the
}
{darn brackets
}
{are all over the place}

Then why the main code is void, but works.

I think StickOS is a bit easier for them for their first intro to micro controllers. But that may be because I don't understand why the brackets are all over the place.

The .hex file does not load. It says that MAXIMUM must be greater than or equal to zero. In fact it is -7xx or so. Here's the error printout.

I can read the embedded .hex file using READ from the PICkit2. It appears to be all in place save one byte at the very end, byte 'c5'.

I do not understand why I need to attach a USB cable to the PIC32 card when the UART tool in PICkit2 looks like it is supposed to do the same thing. Do I need to push some of the buttons (PROG, RESET, USER) to get this thing started?
