external SD in a USB card reader: which path?

hi,
I had just copied my internal SD to an external SD card in a USB card reader by the new SD copy feature:
which is the path to it?
I can't find it to check the contents! :evil:

Re: change HDMI screen resolution manually during runtime?

82 is the only 1920X1080 mode, and it worked automatically for that resolution before I had to force the config.txt changes for the small TFT

Re: change HDMI screen resolution manually during runtime?

writing all that into a bash script, it didn't change anything then nevertheless - all stayed as it was before at 800x480:

Code: Select all

tvservice --explicit="DMT 82 HDMI"
fbset -depth 8
fbset -depth 16

Re: change HDMI screen resolution manually during runtime?

ok - thanks - but now it's getting far too weird to me. I have no idea about all those low level hardware stuff. and how should I type anything if I don't see what I type?

Re: change HDMI screen resolution manually during runtime?

I honestly don't understand a single word.
What is group? what is drive? I only need the resolution!

couldn't you provide the complete commands, please?
no -e parameter?
`tvservice -e ......` to set your required mode
hell, that's awfully weird that stuff to me! :evil:

heya, the new Raspbian version 2016-05-10 https://www.raspberrypi.org/blog/another-update-raspbian/ is really amazing, especially the SD copy tool and some board or interface settings in the preferences, and more. About the mouse settings there is IMO still 1 issue nevertheless: Although I can adjus...

Re: SD backup on the Pi during runtime: rpi-clone? alternati

that tool looks really awesome!
I just have started a SD copy and then will check it.

BTW, is there something like a disk compare tool to verify the SD copy when finished ?

Re: change HDMI screen resolution manually during runtime?

yes, thank you, I saw that already entering tvservice in a terminal - but I still don't see which parameters I have to use for the pixel resolution settings to switch between 1920x1080 and 800x480 (both 16:9) required DMT modes might be 9 or 87 and 82. but, e.g.: tvservice -e mode 82 does not work s...

new Geany version 1.27

hello,
as I am not experienced with update procedures:
I currently have Geany 1.24
for upgrade to 1.27:

can I just use
sudo apt-get install geany
for a new complete installation,
or do I have to uninstall before,
or did I miss a simple update command?

Re: Raspberry Pi with Arduino

you may use an Arduino Due or Mega to generate the pwm signals, both have lots of hardware pwm pins (min. 12, pins 2...13) You can interface them via UART or USB (Due directly, Mega on UART with level shifter!), or you may use i2c to communicate (works just for the Due). pwm on Arduino is 8bit (0-25...
