1. My Development Board came with a small piece part that has "key" stamped on it. Best way to describe it is it looks like rectangular plastic piece with a flat metal piece attached to it. Wondering if this is actually part of the dev board, or something put in by the distributor by mistake. I'l be glad to post a picture if needed.

2. The course current loads Sourceboost version 6.55. I was alerted to updates for the compiler, version 6.89. any problems with upgrading?

I think that "key" is a tool to alter the voltage output on the power supply.

As for the upgrade question, it could cause problems. I'll ask someone here to look at the implications this morning.

Hello Don

Please can you tell me if it is version 3 or version 4 of the C for PICmicros course so I can copy your versions to perform the install.

The Sourceboost update for C for PICs can be downloaded from here. V4 of C4PICs ONLY
http://www.sourceboost.com/CommonDownlo ... stv689.exe

Simply run the install once it has downloaded and install to your C:\Program Files\Sourceboost directory (note if your sourceboost directory is different to this then you will have to edit the install location to suit)

Then you should be able to load and compile files from the course as before. I have tested a few of the programs from the course with this latest version and everything is working correctly with my current configuration.

Thanks..it is version 4.

And also, thank you for the insight re the high-tech voltage adjustment tool..

With 6.89 installed, clicking on an exercise inside the course still opens the old version...6.55. If I then open the 6.89 IDE, it will open with the same exercise I had opening with the embedded version (6.55).

Is this normal behavior, or should 6.89 open when I click an exercise link?

Hello Don

Yes the same thing happens on my PC here. Shouldn't be a problem though unless you actually need the latest version of the compiler to be running.
