Re: partitions problem

in fact, I used a Linux with gparted to extend the partitions without [losing] data. Okay, I'll give that a try using the Pi itself since I can plug the ready-to-change 32GB SD card into another USB slot. W.r.t. to the unusual partition layout where partitions are overlaying each other - did you si...

Re: partitions problem - resolved yet?

Has this been resolved yet? I have essentially the same problem - all the instructions "on the 'Net" are either dated or applicable to some prior version of NOOBS or something. I bought a Canakit Pi with an 8GB NOOBS SD card. Booted it successfully, selected "Raspbian" as the OS, it came up flawless...

Re: parking sensor connection with raspberry pie

Using sensors at every parking spot....Is it like the data has to go to a transmitter for every sensor at the parking spot and it can be sent to one raspberry pie for the whole parking lot. Please do help me out. One Pi is sufficient to handle the largest parking lot assuming you're "sensing" prese...

Re: wpa-psk or wpa-passphrase?

That would be a different problem for another thread - while searching for the answer to the first post's question I found a number of pages noting that there are devices out t...

Re: wpa-psk or wpa-passphrase?

Perhaps they are synonyms? 8-63 ASCII characters in the range 32-126 (decimal). Aren't they both just converted into a 256 bit key anyhow? Not to my knowledge, no - but that IS my question since, as noted, it appears a LOT of people are treating them as synonyms and that MIGHT be the problem behind...

wpa-psk or wpa-passphrase?

I've always used wpa-passphrase in the /etc/network/interfaces file with a string value representing a LOOOOOONG password...in fact, so long it's called a passphrase instead of a password. The syntax would be something like: wpa-passphrase "Thisisawholelotofwords,actuallyASCIIcharacters-upto64ofthem...

Re: Standardized "bit order" of header I/O lines

You're missing the point. No, I'm not....YOU are. For diverse people to interact and design hardware and software that automatically is compatible with one another's software/hardware there have to be standards.

Re: Standardized "bit order" of header I/O lines

If you want to use it as a parallel port then you have to decide on which of the 20 odd lines available will be your 8 bits and map them yourself. You have total freedom to do that. I understand that anyone CAN come up with a mapping from internal-numeric-values to external-header-pin values. The p...

Re: Standardized "bit order" of header I/O lines

Why must there be a "standard" mapping scheme for something that it doesn't apply to? Because it applies to the very real examples I've contrived in this thread. ======= A hardware designer needs, say, 8 bits of data and a "data ready" signal to load the elsewhere-designed device with that 8-bit da...

Re: Standardized "bit order" of header I/O lines

[To set a group of gpios to an arbitrary value you need two writes, one to clear gpios, one to set gpios.
