I agree with local is easier, but that's not always an option.

That's the price of my time, besides I don't want to charge in cash. Feel free to do it for any amount you see fit, I'm not precious about anyone else doing it for whatever they see fit, you could do it gratis if you so chose

Thanks

Three hours is a guestimate, it took most of the morning but that did include coffee breaks, stopping to re-focus my eyes, and at one point hunting for the smd capacitor I dropped, doh!

Can you describe or post a picture of where you've connected the i2c clock and data lines?

I thought that the second i2c channel was not on the main header (but am currently away from my Pi so can't check)

I've seen a few places now where people are asking about pre-assembled gertboards. I don't know if this is something that will ever happen, but in the meantime, having assembled my own yesterday in about 3 hours, I would be prepared to assemble a small number on the basis of a buy one give one for e...

One of my boards turned up today, will wait with anticipation to see if the other turns up tomorrow, although the jiffy bag would probably have been big enough for both.

Guess I'll play the same game as before. Order one from each and see which arrives first. :D Ordered 2 deluxe gertboard kits from Tandy 7pm yesterday, have received a shipping confirmation today and as I paid for express delivery I expect them to arrive tomorrow or Thu. Will post an update when the...

Thanks for that, I'm collating code snippets before diving in myself

Can you post the final code please?

Thanks

just to add, having done some reading it could be to do with clock stretching, but I don't know enough about the linux driver, BCM SoC, or i2c to prove/disprove.

Has anyone else tried hooking one of these up to a Pi? All works as expected on Arduino, so I don't see there being a problem with the chip itself or the wiring. When connected to the Pi I can send one command which is recognised and actioned, but cannot send anything else without power cycling the ...

I can confirm that the DS1307 works without logic level shift (as do a few other I2C devices I've tried) whether this is recommended or not I don't know.

btw, thanks to ksangeelee and Gordon for the more constructive answers.

In order to know that my wording was wrong, you must have understood the question in the context that was provided, so why provide an answer to a wholly different question.. just to prove you know better and people who do not use the correct terminology do not deserve to be helped? You could have qu...

ailwyn

Spot on Gordon, just as the first line of my post stated (in obviously the wrong words) I shall ensure I try my best to use the correct terminology in future, else face the wrath of the pedants :oops: :roll: Mike, if you keep picking up newbies (or even old hands) on terminology that is not really a...

not so... try accessing a tapatalk enabled forum on a tablet or smartphone without using tapatalk and get an annoying popup every time... no thanks.

If the offending bit of code is removed from the script then fine, I'd have no problem, but unless that will happen -1

ailwyn

-1 for tapatalk (yes, it's a minus)

I'm trying to work my way around the need to be root to use GPIO via the /sys/class/gpio. If I were to write a small script to enable all (available) GPIOs at boot, will this cause an overhead on the system, and by that I mean an overhead that would have visible impact, not just using a few bytes/KB...

Conventional bootloaders do not work on a R-Pi. Why? (genuine question) My understanding of a bootloader such as grub is it is loaded at startup and this provides a menu then to start any kernel you like (providing it can access it) - please correct me if I'm wrong. If you created your "grub" and c...

Good enough for me, I'll hold off buying anything for now.

Thanks

Just wondering if the light is getting any closer or whether the embargo has been lifted....? It would be good to know some basic info, either from the foundation or their partner(s) like will this just be a pcb, will there be a full kit of parts, will there be a pre-assembled version? I'm particula...

Thanks both for the replies, that helps clarify it for me.

A slightly related question... at what point do you need to switch from transistor to a relay? Let's say for example you wanted an RPi as a media player in a car, and you wanted it to activate power to the amp in the boot (I neither have an amp nor do I wish to make my RPi a media player - I was jus...

I got my invite to order on 1st April.. duly placed my order and heard nothing since.

One thing worth checking is seller history feedback for the account that contacted you as the foundation did auction 10 beta boards a few months ago...
