UART's echo was ON.

This vehicle reminds me of the original 'turtle' for which LOGO, the language, was developed.

I am on a slightly different tact. I am trying for a robocar that looks like and is driven like a modern automobile. The model level 1/10 sized radio control vehicles fit that description. They have accurate miniaturization and good speed (up to 30 actural mph). This may connect with middle school students.

Once, as I said in my post, Hyperterminal worked. Only once!
I wrote:

If I eliminate ASCII echo and I type 'hello' I do get 'hello' on my Hyperterminal GUI. That is GOOD. Trouble is I disconnected the PICkit2 and reconnected and HELLO no longer appears.

Here's what Device Manager says:

Once, two evenings ago I sat down, turned on Hyperterminal and got 'hheelllloo' when I typed 'hello'. I said to myself that's a good connection. It has echo.

I then went to the UART TOOL in PICkit2. It did 'hello' when I typed 'hello'. I thought that was good so I took a snapshot and sent it to the forum. Then I realized that UART has the same 'echo' or 'no echo' config as Hyperterminal. It was set to 'echo'. Therefore it was not connected at all.

Having done that I went back to Hyperterminal and got nothing again and again and even today. Hmmmm But it did work once.

In no case did I get a response from the code in the chip.
Which leads me to another question.

When PICKIT2 is told to READ it displays what is labeled "Program Memory" into which I thought the original StickOS had been loaded. Am I wrong? When I first hooked up my new PICWhacker to the PICkit2 I did a READ. All it showed was FF's throughout. I just read the spec. pages on memory organization. Page 93 mentions "Separate Boot Flash memory for protected code." Is that visible from a READ? I do not understand the virtual and physical memory charts on Page 94. Things have changed since the Digital Equipment Corp made the PDP-11.

Ok, but after you said that, you said:

Nutts. Wrong again!

UART's echo was ON.

And, you should get a "??HELLO?? command not recognized" or something to that effect back. So I would say nutts, it was the echo.

But I still don't have enough information to advise you any further. I don't know what step you are on.

Yes, the new .inf is different. It is for using with the firmware originally in your UBW32. (Which I believe is only in your untouched device). It is for step 2, if you are on step 2.
