Impact of disabling the dhcpcd service

I have a RPi2 running the latest Raspian image. It is connected to the network through the ETH0: port and it obtains its IP address from my network's DHCP server. (For various reasons the DHCP server provides it with the same IPV4 address every time, but as far as I am aware, the RPi still asks for ...

Re: Python Programming, invalid Syntax

If you are running IDLE, then the cursor will be placed in your source file at the point where the error was found. It should also have a highlight at the spot.
That should help you at least locate where the compiler is having problems.

Re: What is my correct locale?

I suspect that there is a bit of confusion in some of these answers. The OP was asking about "Locale". The 'Timezone' aspect might be wrong but that is NOT the thrust of the question (as I read it anyway). I must admit that setting the locale using either method can be rather difficult and the codes...

Re: Opening .exe in Raspbian on raspberry pi 2

If the 'install.exe' program is actually for a Windows (rather than DOS) level program, then it will probably be looking for things such as the registry and windows-specific directories. While the install program might, I doubt if it will do what it is supposed to do and leave you with a runnable pi...

systemd not stopping weewx daemon

I have installed the latest weewx on a RPI with a fresh copy of the latest (November 2016) Rasbpian. Weewx comes with the old SysV script in /etc/init.d. The only change I've made to that script file is to add in a dependency on $network. Systemd seems to start weewx on boot very well. Also "systemc...

Ideas wanted for total cloud coverage device

I want to augment my private weather station with a sensor to determine the total cloud cover at any point in time (generally measured in 'oktas' or 8ths of the sky covered with cloud) day or night. I have played with the NoIR Pi Camera but there are several things that concern me with this approach...

Re: Can'r Enable VNC

Not quite related but several times I've tried to enable VNC from the config GUI and it has worked until the next boot.
The only way I've managed to get the VNC option to stick is to use the 'raspi-config' command form a terminal.

Re: 100% CPU load

Sort-of but not quite related..... When you interface to mechanical devices such as buttons or switches you need to debounce the signal. Bounces can last for over 5mSec and cause a surprisingly large number of transitions. Adding a 0.1sec and 0.2sec delay is providing some level of debounce in that ...

Re: ARMv8 instructions.

There is no need to use assembler unless you really need the speed in some odd case. And even then you only need to code that part in Assembler and leave the rest in C or whatever. It all comes down to the basics of optimisation: only start to optimise if the performance is below requirements. Even...

Re: Raspberry Pi weather station data logger.

Check out WeeWx - and there are other similar programs - that can connect to a wide variety of weather stations.
I have the program running on a Rpi2 but I'm still trying to get my weather station so I can't tell you that everything works OK - not a fault of the program though.

Re: [Beginner] "Phantom" button presses on GPIO?

Wild guess but I suspect that those wires are quite long and you are picking up EMI (I can see a car in the background - garages and cars can be a very electrically noisy environment). Keep the wires short. Also why not just run 2 sires to the button and have the pull-up resistor on the board where ...

Re: Felt current on Raspberry Pi USB port

You can get this general "problem" when using devices that are not earthed. Using some isolating transformers etc. you can get this effect when the whole "isolated" part floats at some (often quite high) voltage (but generally very low current) above the "earth" potential. When you run your finger o...

As an alternative, have a look for a GPS chip that you can connect up yourself. For a project I'm doing, I have one that needs 3.3V plus a UART connection and 2 control lines (#RESET and ON_OFF).

I must admit that I prefer to run my systems with the latest versions (avoids the obvious advice whenever a problem occurs) but I can stay with the September 2013 version if necessary.
