Re: Dump question: Where is GND?

According to Gert van Loo's document on GPIO pad control, the GPIOs can be programmed to source/sink from 2 - 16 mA, with 8 mA the hardware default. ... Link to Gert's document: http://www.scribd.com/doc/101830961/GPIO-Pads-Control2 The thing to remember is that drive strength is the maximum curren...

Re: Need Help and also a WARNING - DO NOT TRY THIS AT HOME

Re: "Made in China" Raspberry Pi

The "Made in China" label is just a little sticker, easily removed, and underneath is silkscreened "Made in the UK".

Re: "Made in China" Raspberry Pi

I had the same problem with GPIO (you can search for my post). It looks like (as others have reported) that all the Chinese boards from newark (maybe others too) have those same 4 holes filled. Mine does work though, the poly-fuse is questionable (drops half a volt under CPU no load) though. This o...

Re: "Made in China" Raspberry Pi

I just received my third Raspberry Pi from Newark (USA). I immediately noticed that four of the through holes for the new GPIO pinouts were filled with solder. Another obvious difference from previous Pi's was the fact that the RCA video connector was not square to the circuit board and tilted a bi...

Re: "Made in China" Raspberry Pi

RS make all their boards in China, Farnell make MOST of theirs in the UK, but some in China - basically for markets that are closer to China than the UK to save on shipping. As to the issues you are seeing, does the board work OK? The GPIO holes being filled has been reported before, but not the in...

Try:

Code: Select all

arduino= serial.Serial('/dev/ttyAMA0',9600)
Programming languages are so literal!

Did you remove all references to /dev/ttyAMA0 in /boot/cmdline.txt also?

I will send another email to ask what is in going.
Ah, okay, I'll just be patient until it's all worked out then! In the meantime I'm enjoying playing with my second Raspberry Pi, a 512MB model, that arrived this morning.

Re: News articles and blog posts about Raspberry Pi

Weird. AFAIK, Farnell have a few thousand Gertboard's ready to go, and Gert hasn't mentioned anything about any cessation in production. I'm thinking its very badly worded. Have you tried another search on the site to see if there is an alternative? I have done and there is no mention of an alterna...

As a result, your order has been canceled. So, does this mean that there is a new part number ...
