Re: ttk

Are you using the correct import for the version of Python you are using?
In Python 2 you use:

Code: Select all

>>> import ttk
In Python 3 you use:

Code: Select all

>>> import tkinter.ttk
Hope this works. If not can you post the error message you get.

Re: Solderless connector pins for Pi Zero GPIO

Before the advent of the B+, when there was only the Model B and Model A, there was an unpopulated 'P5' header adjacent to the GPIO connector which gave access to the I2S signals for audio. Some Audio cards (such as the HiFiberry, which I've been happily using on a model B for a very long time) requ...

Re: Is a new Raspberry Pi model coming?

jamesh: I agree with your 'guess' about the performance increase of the Zero: I can't imagine that there would be a modified or specially selected SoC in a $5 board. So the improvement is probably due to changes in the overclocking-related entries in config.txt. I've seen a comment somewhere on the ...

Re: External power on LED?

I'll assume that you have connected your LED/resistor between the GPIO pin and Ground (0V) so it is ON for GPIO=1 and OFF for GPIO=0. As joan says, BCM_GPIO14 (pin 8) is the uart TX. Although this GPIO will go ON or OFF as the uart transmits, or if you switch it ON or OFF under program control, if y...

Re: Looking to use a Pi as a media server - a few questions.

AFAIK Plex Media Server does not run on the Raspberry Pi at all.
See here: https://plex.tv/downloads.

There is a Plex client http://www.rasplex.com/ , but the Plex Server would have to be on a PC or similar device.

Re: Set up as WiFi

USB wireless adapters that use the Realtek RTL8188CUS chipset do not work in AP (Access Point) mode directly in Linux. @SirLagz indicates that yours is one of these.

Re: GPIO Robotic Arm

No sorry to be so blunt, but I don't want you to damage your Raspberry Pi! The small motors that drive the joints on the Maplin Robot arm require a higher voltage and far too much current than the GPIO pins can supply directly. You can connect them to the GPIOs via an interface board such as the Ger...

Re: Don your testing hats, it's WiringPi2-Python

Hi,
I got the same error as @alexjames, so it may be pervasive.
Unfortunately I don't understand c so I can't contribute by trying to debug the installer. :(

Great news that wiringpi2 is now available- I became a fan of the original version when I first got my Pi in May last year.

I've added "screen bash" in "Connection > SSH > Remote command" in the PuTTY Configuration for my session. That solves the issue for my three examples.

In layman's terms, as far as the Raspberry Pi is concerned, all simple mechanical switches are the same: They are either ON (short circuit) or OFF (open circuit). This applies to the switches you illustrated, to a common 'light switch' or even to a switch made by just touching two bare wires togethe...

You have entered the following line wrong:

It should have empty brackets at the end:

I made the change, tried it again and it now works as you wanted. :D
