Run Script on SSH Port Trigger?

Hello, I have a rpi connected to a small VPS server via VPN (running OpenVPN). The rpi's IP is not public, yet the server's IP is public, and static. I would like to setup a port-forwarding via SSH from the server to the rpi. Say server's IP is 12.12.12.12 Setup a port forwarding of port, say :4040 ...

Basic 4-Wheel Robot

Hello everyone, I want to build a small, basic 4-wheel robot with a rpi. Where could I start? For the mechanical parts, I believe I will be using motors from a mobility-scooter. Yet, how would you go about interfacing the rpi with the motor controllers? Would you use the GPIO pins to communicated wi...

Re: Cyan vignetting after rpi-update

gorak9000,
Yes, the -st flag is for raspistill.

Try using it in your script (or command).
With the latest updates, plus the -st flag, the odd coloring (vignetting?) went away from my cams!

You are 100% right...
Just checked my scripts, and it is fixed by adding the -st flag.

Re: rPi + 10DoF IMU

Ok, progress!
I added
dtparam=i2c_vc=on
to the end of /boot/config.txt

Now I can list ls -l /dev/i2c* and both i2c-0 and i2c-1 will show up.

If I do i2cdetect -y 1, I get a listing of the 10DoF imu board.
If I do i2cdetect -y 0, I get a listing, yet nothing is connected to it.

How has the Loligo LPS worked for you?

Hello everyone,
I have kept on playing with the code and the IMU module...
Yet I can't seem to get it working properly.

Anybody have any insight as to why the accelerometers are not getting any readings?
And why would the Gyro readings continue climbing for ever?

All help is appreciated!

Odd.
When I run the -st flag with raspistill I get:

Code: Select all

Invalid command line option (-st)
Here is my full command:

Code: Select all

raspistill -st -n -w 800 -h 600 -q 50 -o photo1.jpg -e jpg
