Which Raspberry Pi do you have?

fangfufu

If I put

dtparam=spi=on

in my

/boot/config.txt

, my UART pins stop working, after booting up. The login prompts don't show up. Is anyone else experiencing the same problem?

I received my Raspberry Pi Zero W. I tried to configure it as a USB Ethernet gadget. It doesn't seem to be working. I tried following this tutorial: https://gist.github.com/gbaman/975e2db164b3ca2b51ae11e45e8fd40a This tutorial works fine for Raspberry Pi Zero v1.2 So has anyone else tried what I did...

I don't think lcdproc has native support for the backlight control. A quick Google search led me to this thread.

fangfufu

The last time I used my Pi Plate was probably 2 years ago. I did mess with lcdproc, but I can't remember if I messed with the backlight colour. I vaguely remember that if you don't ask lcdproc to turn the backlight on, you can manually change it to the colour you want. But I honestly can't remember ...

fangfufu

I hope I am not breaking the forum rule by replying to a 2 year old thread. I suppose you are saying that basically LCDproc cannot control Adafruit LCD Pi Plate's backlight colour, right?

I am genuinely surprised that somebody is actually using my code...

That's normal behaviour for screen. Pressing Ctrl-d is the same as typing "exit". You're ending the process that is running in the screen session.

GNU Screen works in a weird way in the image generated using your script - detached screen terminals get terminated when you log out. To test this, you need to connect to your Raspberry Pi 2 via SSH, and then do the following: $ ssh $IP_ADDRESS $ screen # type in ctrl +d to detach your screen sessio...

Thanks, it is really useful.

I don't understand the dbus part. What does it do? Do I actually need it, if I am running my Raspberry Pi headless?

fangfufu

This thing apparently has Raspberry Pi inside them!

I have run Doxygen on the driver code released by Broadcom. I am not sure how useful these are. I have posted it here for whoever wants to use it.

I turned on both caller graph and call graph. This somehow results in a folder that's 4GB big.

I wrote some user space program to replace the hwclock. No, it can't be used as rtc0, but you can write a RTC driver for it. I decided to replace the hwclock with my user space program instead.

Hello everyone,
Is the pre-compiled kernel headers available anywhere?

fangfufu

thanks dom!

I suppose I could filter out duff readings too, but that's just masking an underlying problem. I suspect core_freq affects other buses' speed. Apparently it could cause problem to SD card too. http://elinux.org/RPiconfig#SD_Card_Usage_with_Overclocking I will just lower the core_freq for now. I migh...

Hello guys, I bought one of those Web4Robot Weather Station Board (http://www.web4robot.com/PiWeather.html). Problem occurs when I set the core_freq in /boot/config.txt to 450. I get strange readings. When core_freq = 450: fangfufu@snowden:~/Pi-Weather$ ./Pi-Sensors Board Version: 1 Board Temperatur...

Hello guys,
I wrote a C library for Adafruit RGB LCD Pi Plate. Any comments and suggestions are welcomed.

ffmpeg is not in Raspbian repository, mate. Debian switched to libav a while ago now. I think it was due to some dispute within the ffmpeg development team.

fangfufu

How do you know for certain why it won't work for armel? How about people who use Arch Linux? I simply can't locate that file. I am pretty sure the problem will be solved if I can find that file. I use Debian because I like the ffmpeg from the deb-multimedia repository. I don't want to have to compi...

fangfufu

I rebooted, and it complains that file is missing. I am not using Raspbian. I am using Debian armel. I did not boot into the normal X environment.

I am trying to get Wayland Weston working on my Raspberry Pi. I use Debian armel, so I have to compile the whole thing. I followed the instruction at http://wayland.freedesktop.org/raspberrypi.html. The whole thing compiled succesfully. However when I try to launch Weston, the following error messag...

I bought one, my air pressure is wrong. It is reported to be 89.1 kPa, but it should be around 100kPa.

fangfufu

Dom, it seems that overvolting and using the performance governor doesn't void the warranty. You might want to address this problem. Also the new turbo mode (1000MHz ARM, 500MHz core, 500MHz SDRAM, 6 overvolt) is unstable for my particular Pi. My stress test method is running, dd if=/dev/zero | ssh ...
