opengauge development: gunio technical considerations

[jimboradley]

Yes, COM1 gets removed from the list when I unplug the cable. Not sure if I said this before, but I wired up the ends of my serial cable as a test plug (handshaking lines tied together and rx tied to tx and I received back what I was sending with the Arduino serial monitor, so I'm pretty sure I'm transmitting and receiving correctly on the USB to serial link.

I don't need to put any jumpers on for the serial version of the board, right? Just if using external power on the USB version?

Also, I was foolish enough to order the serial version before I checked to see if either of my computers had a serial port, that's why I'm doing the USB to serial converter cable. If worst comes to worst, I suppose I'll just have to buy the USB kit, though that's basically doubling the money I've already sunk into this.

Well, it isn't all bad. If you buy a USB one (with the dip socket), you can use it to program just the chip for the serial one, then put the serial one in your car and you will still have an arduino on your desk to play with

Here is another *duino that is cheap and has a very small form factor. From Makezine...

Sparkfun has a great tutorial on finding out the right enclosure for your project. I thought this could be a useful reference for the Opengauge.

Here is another small form factor duino that looks like a real bargain @ < $18.00. It comes with usb connector and would fit behind a 2x16 LCD:

I am currently using a USB to Serial adapter to program my arduino. It doesn't work "out of the box", but if you aren't afraid to open it up and get a little dirty, you can make it work. I have a write-up on my site that will show you what to do. The chipset may be different, but the basic concept will still apply.

Hope this helps!

Wow, you totally owned that USB adapter

I might suggest a USB to TTL kit for $7.90 though

(or the assembled one for $11 if you don't like SMD kits)

By no means is my hacked adapter the most suitable solution!
There are lots of other options out there, including the ones posted above. In my case, I didn't feel like waiting to have one shipped, so I figured out how to do it with what I had on hand. I'm slightly insane that way, spending way more time and effort (and sometimes $$$) to reinvent the wheel!
But hey! I have tons of fun doing it, and it is also furthering my self-education in electronics.

Well, it is nowhere near as crunchy as your rig, but I'm using the iduino as a USB p4 type programmer at the moment (reset button works too ):
