please help create radiogroup/radiobutton sample

[ryan mcaloney]

im trying to make an app with at least 2 radio groups  with 3 radio buttons each to turn pins on and off

im an extreme newbie to ioio (went through 3 already) and also to java

im able to compile and use the samples provided but i cant seem to get the radio buttons working with pins, i cant even get the sample to work with more then the led_.

im waiting on my local library for some basic java books but im wondering if someone might be willing to help ive been wasting so much time and money i could even offer some money for help

Thanks Ryan

Would you post your code? Also, why do your IOIOs fail? And in what way? How are you powering them? What are you connecting to them?

I think its more likely that I destroyed them not really a failure but the first one I bought from jaycon and I ordered a jst connector they had I hooked the jst pigtail to 12v from a cigarette light of a car and it lit up like a sparkler on the 4th of july. not sure if the pigtail red wire was actually + or if it was just too much power jaycon never replied. the 2nd the micro usb connector came off and the 3rd I havent managed to destroy yet.

all that aside im really enjoying the ioio and what im learning from it you made a really awesome device thanks.

so my code is really helloioio hacked up to not work!

my edit of main.xml seems good for what im trying to do but MainActivity.java is where im having trouble connecting the radiobuttons to pins. ive tried many different ways with mainactivity.java but i just dont know enough and my books cant get here fast enough.  I know its ugly and probably all wrong and definately incomplete but heres what ive been basically copying and pasting and trying this morning.

1. The 12V cigarette lighter outlet of cars is often unregulated and can jump to 100V or so during ignition. You really don't want to connect your IOIO directly there... Use a regulator that is designed to be plugged in to a lighter jack.
2. MicroUSB connector coming off is often a sign of sub-par manufacturing quality. Buy your boards from SparkFun or SeeedStudio if you want to get boards which I can personally vouch for.
3. I see nowhere in your code any attempt to actually do anything with the radio buttons or pins. If you don't yet know how to use radio buttons, this is unrelated to IOIO and the Android developer site has great tutorials and examples. If it is the IOIO part that is causing you confusion, what you want to do is simply open more digital outputs from your setup() method and then write() to them in your loop() method, just like it is done with the on-board LED. The IOIO Wiki on Github has good explanations about all the IOIO APIs. Check it out if you haven't already.

I wrote hoping someone might be able to give me an example of 1 or 2 radiogroups turning on a couple pins and from there i could build on it. 

my trouble is being a newb to both java and ioio, ive spent alot of time on github and all across the internet, the ioio isnt whats giving me trouble its my lack of knowledge.

[Ytai Ben-Tsvi]

This is a pretty specific request. While it is possible that someone else has written exactly that, it is not extremely likely. It is probably better for you to just learn how to do it yourself. It is really not that hard and there is some very good documentation and tutorials out there to help you get started.

its amazing how much this one sentence helped me "what you want to do is simply open more digital outputs from your setup() method and then write() to them in your loop() method, just like it is done with the on-board LED" from that tip i came up with what i beleive is working code.

Thanks
