Re: Current draw from GPIO pins

The site does not explain all the restrictons. From a document (can't find it now) I read on this site years ago, the maximum curemt that can be drawn from all the pins at the same time should not exceed 55ma, and the current drawn from any one pin should not exceed 16ma. For the moment ignoring the...

Hello, rpDom How about for NOOBS, because it only requires a smallish partition for the install, your program could write a default blank formatted partition, then put the NOOBS files in it. The size could be fixed at just big enough for the NOOBS files (allowing for future increases)? That would sa...

Re: A modified Win32DiskImager for Pi users

Hello gjennings,

I think I've found the cure.
If you would care to download all the files again, it should work.
I've uploaded some extra files that seem to be needed .
I tested by renaming my QT dirs so the system couldn't find them and it ran OK.
Otherwise I don't know the solution.

Re: A modified Win32DiskImager for Pi users

Hello gjennings,

I think I know what the problem is.
It seems that some of the files in my QT installation are refered to by the program.
I can replicate the same errors by renaming my QT directory so it can't be found.
I'm not using Visual C++ but Qt creator.
I'm searching for a cure.

Re: A modified Win32DiskImager for Pi users

Hello mikerr ,

On the file search, it defaults to *.zip / *.ZIP, but you can search for *.img / *.IMG or all files *.*
No, it does not expand *.zip files.
The image is just showing the *.zip file hash, but its a nice idea to go from a zip file to an image on the SD card.
I'll have a play.
