The gles3 book samples all compile and work unmodified (https://github.com/danginsburg/opengles3-book) with cmake and libgles2-mesa-dev installed - at least all the ones I have run so far worked.

Install libgles2-mesa-dev, this gives both the GLES2 and GLES3 headers.

With cmake installed, it was trivial to build all the samples from https://github.com/danginsburg/opengles3-book. Everything I have tried has worked.

That would imply that it is included in the standard 4.1.13-v7+ kernel that I'm running, at least. It's a module, not compiled in to the kernel image itself, and so can not be used to mount the root file system. This is why Jon Archer's method works on F21 (which has the second partition as ext4) b...

From memory, I don't think the kernel from the foundation has xfs compiled in (I seem to remember hitting this myself) which is why the instructions work for F21 but not F23 (where the fedora arm root partition is xfs). Instead, look at the thread on a respin by vaughan - https://www.raspberrypi.org...

From your output, the script is configuring the build for an x86_64 host, and not arm. This is why it can't build a usable executable. ../libusb-1.0.18/configure --disable-timerfd --disable-udev --disable-shared --host=x86_64-linux-gnu --prefix=/home/pi/Desktop/hauppauge_hdpvr2_driver_ver6/3rd-party...

* Is possible to install the Raspberry Pi and get in working and then shutdown and remove all cables except Power and network. Will it bootup? Yes - this is called "headless". You can access the pi remotely using ssh (from linux) or putty (an ssh client for windows). * What happens if there is a po...

Just looking at the examples on the filebot site, the basic calling convention is filebot [options] path [more options] Each option is an option name (e.g. --def) followed by some data (e.g. ut_label=tv). When you run a command line program, the arguments are passed to the program by breaking them u...

You only ever set the value of the variable spinState at line 24.
Adding

Code: Select all

spinState = GPIO.input(18)

before line 47, so you read the state of the GPIO on each loop, should resolve your issue.
As an aside, I would normally add a sleep in this loop, so it doesn't run at 100% cpu usage

Just a guess, but I think it has started "vi" for you, to edit the file. If you type "ZZ" (that's capital Z twice) does it exit?
You can change the editor it uses by setting the EDITOR environment variable. For example:

Code: Select all

export EDITOR=nano

Firstly, I think you are making too much "static" in your class. "static" means there is only one instance of this variable, shared between all instances of your class. Secondly, you are invoking a static contructor using the value pin before pin is initialised. Try something like the following: pub...

I had the same symptom with the workstation image, but not with XFCE, which worked fine. If you just want an image, user vaughn created one using the proper respin tools, see https://www.raspberrypi.org/forums/viewtopic.php?f=51&t=122403 . If you are more interested in doing it yourself, I can cross...

If I type nano /ect/apt/sources.list then it tries to create a new folder.

That should be /etc, not /ect.

Pimoroni do these starter kits:

That gives you everything apart from a monitor with an HDMI input to plug it in to.

I haven't used this device, but have used the adafruit 16 channel, which seems similar. As you say "it just spins continuously", is this a continuous rotation servo? Have you set up "standard mode" on the device (address 20, value 0) What value are you setting on servo 0? 127 should give 1.5ms pulse...

Maybe take a look at SDL, although I haven't tried it with a touch screen, and Kivy (python, but well structured and there are examples of it working with the RPi touchscreen, including multitouch support)

Actually, my question may suck. Since every graphics are based on x or wayland + gpu drivers, I am wasting my life trying to implement a new stack.. Am I right? You don't necessarily need X/Wayland, OpenVG or OpenGLES will both work on the raspberry pi without running X. However, writing a custom O...

The official instructions are for building the whole kernel and all modules. My instructions cover getting just enough in place to build a single module - in my case it was the XBox 360 big button controller https://github.com/micolous/xbox360bb

hexelpdkk

I wrote some instructions a couple of years back that might help: see https://paulspiblog.wordpress.com/2013/ ... he-kernel/
Obviously kernel version numbers have changed since.

Can I remind people that the code being discussed is from a member of this forum - please be constructive rather than insulting. Apologies if what I wrote came across as harsh, I was actually trying to get across that I could see where the OP had difficulties. Additionally, I meant my code to say t...

This might work (it does over ssh to an old centos virtual machine)... Try setting the DISPLAY variable in the ssh session. Log in as the same user on the pi as over ssh, open a terminal on the pi, and type "echo $DISPLAY". This will give you something like ":0.0" Then on your ssh session, set the D...

This is mostly made difficult due to the very light documentation on the supplier site. A board schematic would make life a lot easier. It is worth taking some time to look at the multiplexer they use http://www.microchip.com/wwwproducts/Devices.aspx?product=MCP23017 which was referenced in the blog...

Your first line imported the module, giving you access to things inside it only if you use the module name as a prefix. So you could access the class as follows >>> import tm1640 >>> tm1640.TM1640(clock_pin=3,data_pin=2) My line imported the class inside the module, so you can use it without the mod...

hexelpdkk

How about:

Code: Select all

from tm1640 import TM1640

Have you tried what it says in the error message?

Can't open the mysql.plugin table. Please run mysql_upgrade to create it.

I wouldn't expect this on a clean install. Normally you have to do this as you upgrade across particular versions.

You need the Adafruit I2C module, which you can get from https://github.com/adafruit/Adafruit-Ra ... afruit_I2C

Put the file in the same directory as Adafruit_ADXL345.py
