Using the USB-6008 for D I/O

[AnalogKid2DigitalMan]

Sweet, I want a ride!

Always thought it would be cool to have my own personal hovercraft for land/water recreational travel.

Once i get it up and going, i'll post some videos on you tube:).

Also, Justin,

My group decided to throw a servo at me so we can control the throttle of the engine. Should i just go online and buy a servo controller or is it possible to use one of the extra channels in this controller to control the Servo?

Servo takes a little more effort to run smooth. I have had success with the printer port on my computer (but it wasn't super smooth).

That being said, that Sparkfun platform is more than enough to do what you need (but you'll need an H-Bridge) if you're willing to modify the code (an EE student over there could help you).

*A reasonable prebuilt servo driver is here http://www.hobbycnc.com/products/hobbycnc-...ver-board-kits/

could you use one of these on one of the extra PWM channels?

Justin,

I just got the prototype board in, and im expecting the digikey stuff shortly. Once i get everything, should i hook up the programmer and have at it? I was wondering if you had code I could work with to get started. I remember you saying it shouldn't take too long after i get everything to start using the chip .

thanks alot! hope your weekend went well.

-Jim

*also, an EE student over here had some chips he already programmed for a servo to lend me, so i think i should be okay on that side

[Justin Reina]

Hey jmt,

Which kind of servo are you referring to? I would recommend keeping it to one chip if you can, and a Hobby Servo (servocity) might work best for your situation and should be around $20.

btw, here is my testbench for the uC. So far I have two PWM and the ADC written and working. Should take care of the rest this week I think.

Justin,

My group bought 2 Futaba servos (model S3306). They didn't really bother to mention that we needed to use servos until after they bought it :thumbdown: ... lol, do you think it will be okay to use?

-Jim

[Justin Reina]

Yeah that's a hobby servo. Pretty simple to use (PWM) and prob pretty good for a throttle.

Justin,

Got my chips and programmer in the mail today .

going to go download the software onto my computer now, just curious tho, how should i start wiring thigns together?

-Jim

[Justin Reina]

I'll have to get back to you tomorrow. Busy Today.

-Justin

Try installing AVR Studio 4, and confirming connection to the ISP unit. Then try to get the ISP unit to recognize the uC on the board. Here's a .hex file to flash a pin.

Justin,

No worries... im not in a rush at the moment. One thing i noticed was, the programmer has a 2x3 pin interface and the proto board has a 5x2 pin interface. So I'm thining i may have made a mistake?

-Jim

[Justin Reina]

Check the subdir. Three progressive trial codes.

There are two different ribbon headers for ISP, a 6-pin and a 10-pin. You're gonna have to make an adapter , but its just a matter of wiring.

Hey jmt6009,

Started a new thread for this topic, thought it might be useful info for others:

http://forums.lavag.org/Microcontroller-PW...nch-t13796.html

Check out the info there. That should be enough to get you acclimated and running. If you have any questions (pretty sure there will be some ) don't hesitate to ask.
