I give up .. no point continuing this if all you want to do is defend a confusing statement when someone asks for clarification.

this is emphasizing

THIS IS SHOUTING

learn your net etiquette

Its nothing I made up I have the right to put my ideas in my way

Yes it is there is no such thing as "Deep Trodden" rooting. I Simply asked you to explain what that meant and you said "it just means rooting", therefor you made it up. I am not suggesting that coining expressions is a bad thing but your terms are a little confusing.

READ WHAT I POST CAREFULLY BEFORE MAKING REMARKS

Now shouting is just plain rude, but in keeping with the tone of your responses , so I am not surprised.

I suggest that you take a leaf out of your own book and read the post and its thread before posting. especial in light of the fact that you said that rooting is done to gain access to the USB port but the OP clearly states that he has this already.

You seem to be being very defensive about this, I am not sure why. All I asked for was clarity on your original post which was confusing and using self invented expressions.

Cheers Pete.

There is no such thing as deep trodden rooting, rooting is rooting or according to WIKI ( http://en.wikipedia.org/wiki/Rooting_%28Android_OS%29 ) gaining access to the kernel of the OS with administrator rights. There are no levels of rooting, Deep Trodden or otherwise mentioned.

Could you give me an example of Deep Trodden routing. I am learning this as i go along and any knowledge would be useful.

Deep trodden rooting means rooting only, its just the way to put it forward and may include bootloader unlocking because if you can understand rooting ,rooting means getting deep into the realms that are not controllable else you root the device, Hence rooting is always Deep Trodden.

That is interesting , every android device that I have use OTG USB interfacing with does not require "rooting" Admittedly I have only tried connecting FDTI chipset based USB-> serial bridge hardware but never had to root my device to gain access to it.

"That you have used" this is something not to explain here OTG devices are OTG devices that have Host controller chipset they are found in new versions ,there are tons of Android devices without any OTG support what about those and Even in the case of some OTG  supporting devices there is still need to root the phone and get the access to the specific functionality in the Kernel, a classic example to this are 2 year old phones from now, I have 2 of these which support USB OTG only after rooting and which also emulate Serial ports only after rooting and without Serial port emulation whom you are going to talk with, phones ass maybe.

How do the applications in the android store do this without root access.

Many of the Apps on the Android store don't work with unrooted phones and some work they work with high end devices which have OTG, you need to read the description of these apps in detail.
The fact that many USB host controller apps, stick mount apps require rooting, thats very common requirement called from such apps.



Ahhh OK so "Deep Trodden" is just something that you made up and does not actually exist, thanks for clearing that up.

I do believe that most new devices on the market these days do have OTG support .

perhaps you missed the post where the OP said .......

Yes i have an OTG cable and my phone support the USB Host mode.
I can connect pendrives,mouses,keyboards and controllers to it.


So I guess it does not need (Deep Trodden) rooting.

Cheers Pete.

Why would you need to root your android device in order to use the USB port with a USB-> serial adapter

Because every Android kernel won't give access to its drivers down under which are not to be utilised normally, I have done this several times with Android devices at my disposal, they dont have serial port emulated without rooting.

what is "Deep Trodden" rooting as opposed to plain old rooting ? I am confused .

Rooting is always Deep Trodden never plain old as such.

How do the applications in the android store do this without root access. Perhaps I have been lucky with my choice of hardware. I am not suggesting that it is never required. That would depend on the manufacturers choice on accessibility of the core systems. That said however I have not so far found any devices that would stop me gaining access to the USB.

Android always have drivers for dealing with the Serial protocol on the usb its just that they may not be accessible without deep trodden rooting sometimes of the phone!

contact me if you may want it done.

Why would you need to root your android device in order to use the USB port with a USB-> serial adapter  and what is "Deep Trodden" rooting as opposed to plain old rooting ? I am confused .

Hello Philip,

I am a Brit (Welshman) living in France. I can help you with your project. I do a lot of work for people taking ideas from POC through to production as well as one off systems.

I have a few UK based clients who I work with as well as my USA, Canadian and other world wide clients. Working remotely is not a problem for me.

Take a look at my website WWW.EmbeddedAT.com
 If you think that I can help you please drop my an email for a chat about your requirments to Peter@EmbeddedAT.com

Cheers Pete.
52  Using Arduino / Project Guidance / Re: Shorten code (help a noob!) on: June 28, 2014, 08:43:55 am
Code:
     digitalWrite(2,LOW);  //How do I shorten this?
      digitalWrite(3,LOW);
      digitalWrite(4,LOW);
      digitalWrite(5,LOW);
      digitalWrite(6,LOW);

becomes

Code:
for(uint8_t i = 2; i < 7; i++)  digitalWrite(i,LOW);

hope this helps

Cheers Pete.

send it as two 8 bit bytes and then re assemble it at the receiving end

using a uint 16 and add the first byte in then bit shifting the second byte and or-ing it with the first byte into the 16 bit unint

Cheers Pete.

If you can provide me a sample code because i could find one

look what a simple Google search reveals

http://forum.processing.org/one/topic/read-a-16-bit-data-from-serial.html

Hope this helps.

can you show the diagram exactly?  its hard for me to read words sometimes without pictures.  So after one gate add a resistor then so on?  all connected in series?  or parallel?

It would be quicker for you to Google it, than come back to me if you are unclear.

A nice PID might also be good to soothe out minor fluctuations or even do a bit of predictive so that the display remain stable during acceleration an deceleration


Excuse my lack of knowledge, but what is a PID / how do I set it up and use it?

Try goggling it first, then if you dont understand it come back to me.
57  Using Arduino / General Electronics / Re: help with transistor output on: June 28, 2014, 07:11:30 am
you can drive multiple MOSFET gates from a single Arduino output, be sure to use a resistor for EACH gate however.

Cheers Pete.

The sensor needs to react very quickly as the wheel will be revolving very quickly (around 1000rpm) and it must be precise.
A bike wheel @ 1000rpm?
Like 16.6Hz?  smiley-eek

A very fast motor bike with very small wheels perhaps smiley

Yes a hall sensor is the best way to go on this.

Dont use a integrated hall switch , just get a hall transistor and do a bit if signal conditioning. it will be good for a few khtz

You need a fixed point of reference from which to start your display calculations.

A nice PID might also be good to soothe out minor fluctuations or even do a bit of predictive so that the display remain stable during acceleration an deceleration

The debate isn"t over.  One of  the downsides of making " hacking" (I still have trouble accepting that term) is that many  Newbies
confuse / abuse hackong in that they become (or are) lazy and won't take the time to research or Google anything and judt post on
the forum asking/demanding code and schematics.

Yes .. I understand that.. but does it really matter if they are having fun and not planing on becoming rocket scientists.

Telling someone that they cannot do something unless they follow, what for some people can be quite difficult, theory is not a great way to get along with your fellow men (women).

If these newbies frustrate you so much just ignore them and people like me will continue to help them.

Sometimes people just need a little hand holding, they may then go on to do great and awesome things paling our skills into the shadows. I am not protective about my hobbies and I dont demand that a certain bar be reached to participate.

Cheers Pete.
