mistaken. Just curious on how to wire it up to get started.

Hey - found and read through the documentation, sorry about post prematurely. I
am trying to confirm the installation of my pro.

I have a USB to TTL FTDI cable that i picked up as well [ftdichip.com], and I
installed the USB driver. The device shows up on com6.

According to the documentation it appears that I need to install a two pin
jumper [C Jumper]. Is this correct? I have a two pin but no jumper block. Is
it a big deal if I go solder this on? I.E what functionality do I stand to
loose?

Cheers,
Shane

Hey Shane. Congrats on the purchase. Welcome to the group.

Bruce will chime in here shortly, I am sure. But, to throw my $.02 at ya, it is
my belief that you will not want to solder them, but rather use a the two-pin
header and a jumper cap. You should be able to steal a jumper off of any old
hard-drive/CD-Rom/Mother board if you have any of those handy.

I do not have a pro, but I have a number of other Coridium products. It is
likely that you'll need to install the jumper to affect the programming and then
remove it for the program to run...

I just confirmmed this. Take a peek here:
http://www.coridiumcorp.com/ARMhelp/index.htm. In the index pane on the left,
expand the Hardware Specs branch and then select ARMmite PRO pin diagram.
Therein it serves to illustrate all of the interconnect options that you have
available to you with the product.

Take care!

Ah thanks for the heads up Tod. I got it working!

I dug in my spare parts box and found the header. I will go ahead and solder
the pins in then I can just push the jumper on when programming etc.

Cheers,
Shane

I just got back from the Maker Faire, never been to one before, pretty
impressive.

If you use the FTDI cable (from MakerShed) or the SparkFun USB dongle, you do
need to pull the load C line low (available on the jumper or next to GND on the
cable. These 2 cable setups use that as a output to the host, though I have yet
to see any software that uses it.

The load C line (P0.14) tells the LPC2103 to come up in what NXP calls ISP mode,
for in system programming. It allows you to load a C program, note that this
erases the BASIC, so if you wanted to try out the BASIC do that first.

The USB dongle Coridium packages with the evaluation kit drives that line so the
jumper is not needed. Rather than solder a jumper in, I have used just a 2 pin
breakaway header with a shorting block, there's a picture in the Getting Started
section of the C help file. The only potential thing you lose by soldering in a
jumper is the GND pin if you wanted to connect up a Vdrive.
