There's a ready built DT overlay that should work with that TFT. Add dtoverlay=rpi-display,rotate=90 to /boot/config.txt. shutdown wire it to the SPI interface using CE0/CS0 wire the following pins: rst ==>gpio23, rd or wr? ==> gpio24, backlight led => gpio18 reboot So: SCK -> GPIO 11 (PIN 23) MOSI...

OK, so I have the documentation now, but I doubt if I could read it, I'm not that professional, can some one read it for me?

That's the TFT board I have brought for $30. But how do I use that? I know GND and 3V3 but, I don't know the rest of them.

Before we had USB 3.0, let's have eMMC first. USB3.0 controller is still costly nowadays.

I know there's a lot of GPIO TFT shield out there, yet they are small(3.5-3.8 inch) and cost-ineffective(>$25) which is not really compatible with the project I was doing. I could have bought a 4.6 inch TFT with controller board (ILI9486) for $30, however I haven't played the powerful-yet-difficult ...

One of the more interesting clues recently is the https://www.youtube.com/watch?v=L991wyOHTJ4 Raspberry Pi Guy interview with Eben Upton. Starting around 5:48, they talk about the Pi 2 A; Eben specifically says that they could make a list $25 Pi 2 A w/ 512 MB RAM right now, but they really want to ...

I think Arch Linux is a good choice. Unless you're a new Linux user and have never encountered Arch or Linux before. It's also a right royal pain to install after the Arch folks stopped building SDCard images. Small and simple are: raspbian-ua-netinst (which is well established) and Raspbian Diet-P...

Wait, in Raspbian you only have one account in default, and that is root, so what I have told above were bulls. Anyway, you are facing permission problem with your file, this one should fully solve the problem chmod -R +x /home/pi/mine/bin/ Before you distribute or want to redeploy your PocketMine ...

but there are a lot of full version of Minecraft out there, and we only have PC version gift code selling in shop so I think it was Minecraft Retail.

They've just advertised for a new charity CEO at £100k a year. http://www.cambridge-news.co.uk/Raspberry-Pi-foundation-Cambridge-advertises-new/story-26001955-detail/story.html hundred thousands for a CEO/year? It seems the foundation is not a crazy at money at all... Back to the front, how do you ...

Performance-wise they are quite close for general purpose use, thanks to the quad core ARM, but when it comes to emulation, single-core performance is what counts, so the Pi 2 would most likely be considerably slower for that purpose than an old Atom netbook. Emulating x86 too is necessary on the P...

one core of Core i3 of any version already beat the CPU of Pi 2. Silly comment; but to respond - Cost, size and power requirements ? ;) The closet Intel CPU for Pi 2's is N270 my guess, N270 runs Linux and Hackintosh(yup) quiet well, but I have to wait for 30 seconds to boot up the Windows, even if...

cia48621793

Me too! :P Four Xeon cores will do that, but it's not entirely realistic on a Pi. And 100000 active connections are not a realistic workload anywhere, http keepalive makes the standard situation lots of connections but only a minor portion active at any one time. In the meantime, here's a benchmark...

As above, there are lots of interrelated things that will makes things between 2 and 30 times faster. Multi cores means when using the desktop all the graphics processing can be moved off the core doing your application work, so even if single threaded, you app will have more of the CPU to use. Mor...

My Pi boards hardly ever see a mouse, keyboard or monitor. Those things don't fit well with my robots and other Pi powered gadgets. Yes I use a 10 dollar WIFI dongle for network and you need an SD card. Hardly a huge expense. I do not use Linaro or any other cross compilation tool chain. The Pi and...

launch the bash script with root permission, in Raspbian you can use sudo ./start.sh , while others such as Arch Linux or CentOS, you will have to go root using su . If you are using Raspbian, you can install the PHP from apt-get: sudo apt-get install php5 Or Arch: pacman -S php5 CentOS: yum install...

In Windows you will have to go Linaro, but I'm having issue with my Cygwin and MinGW, have to do a full wipe of my Cygwin for the sake of Pi 2.

I would like to see 100K(not kelvin, kilo) active requests in multi-core.

cia48621793

I know Pi 2 was $35, but it was not a full solution, you still need a mouse, keyboard and a monitor, and of course internet. Also Linaro is required to do cross-compile. I'm also curious about how much is the parts of Pi 2, like CPU, RAM, USB port and sort, and how does the Pi Foundation profits fro...
