- Fri Jun 26, 2015 4:21 am #21737 Sorry if you felt it this way.
I don't want to push someone who is down.
There is a lot of confusion, wrong assumptions, wild guessing etc. going on here and you can only judge
people by their words.
I am not a native speaker and that makes it even more difficult.
I tried to choose my words carefully but obviously failed.
Flippy australians, boringly serious germans, grumbling russians. It's a colourful mix.
Let's try to calm down and try to make clear what are facts, assumptions, works for me, etc.

Let's have fun,
Cal

This guy obviously cant accept that he might be wrong in calling me wrong . Go whichever way you want, but high or floating are definately correct and no-one is wrong . I am fed up with his stupidity-same post four threads

Ehhhh ! Guy, look and re-read my post !!! I've never flamed you, I have simply stated the true about facts and basic that any electronics engineers agree with. I'm part of those, NOT you ! Simply go back to school to learn those basics. If I posted four time the same things, it is simply because you have posted so many time the wrong argument that GPIO2 should NOT be pulled-up but left floating, you even pushed your argument saying we need to change this Wiki Boot Process table to put an X instead of H, for which I prove it to you yesterday that X means I can decide to put it to L without any effect. Who is REALLY WRONG here ?
You says that I have posted "stupidity" ? Ask real engineers to see if what I posted has any thing wrong, prove it !
And ask yourself about you own posts if they are stupid such the following :

If I wire up 2 1.5 volt batteries in series I get 5 volts
If I wire up 2 more and put them in parallel you will find that an acceptable 5 volt supply

First 2x1.5V != 5V, Secondly, I hope you never did that with Lithium batteries in parallel ! You can ignite fire in your house !
And here is another one from viewtopic.php?f=13&t=3533&p=21359&hilit=arduino.cc#p21359 :

You will have to add an interupt somewhere . See Arduino.cc interupts.

Did you ever think that the UART is also in Sleep Mode ?

Seems a few people have barrows to push around the place Cal . As a full call ,ham radio operator in Australia the study and knowledge of radio and electronics required is extensive . I fancy myself as a bit of a Yagi specialist . I understand antennas. Normally I would not reference that fact but your speech necessitates it . look me up VK4AAZ until I no longer required it. So as they say don't tell me about boats.Hi Hi

I'm a bit disapointed with your speech though. Its a bit like trying to kick a man when he's down and thats not acceptable conduct here in Australia and in many parts of the world still. Things like that are never forgotten .

Now on the technical side, not connecting the pin as per the connection diagram not only works for me, but for many many others I gather .Look around . You can take it high if you feel that is safer but it is incorrect to say I am misleading anybody by telling them to leave it unconnected. At no point have I said its a "don't care " thats just been made up and shoved in for effect I fear although I admit at one time I interpreted the Olimex board jumpers that way . That was a really confusing piece of work by Olimax.

I've also said that I am going to make many mistakes in posts. Thats the nature of the device we bought to play with and the learning forum we joined . I hope you might see the merit in my post.

First, I'm suprised that you're calling yourself a Yagi specialist and still argue that floating pin is better than pullups !
And about Olimex, did you ever opened that schematic from https://www.olimex.com/Products/IoT/MOD ... ematic.pdf ? Please, do your homeworks !
It is clearly shown that options for those jumpers on GPIO0 and GPIO2 are GND or VCC (Not floating) and the Boot-Process table is also shown on this schematic :

So, please, not only re-read my posts, but YOURS too ! and withdraw YOUR flamings with excuses, especially since myself I've never flamed you in first place !!!
