#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

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 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 ?

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 !!! :evil:
