Cannot activate picam support anymore

A while back, I have purchased two camera boards (picam). I was able to get them working, but lately I have issues with them. I try to run my python script, but it keeps telling me to enable camera support through raspi-config. I do this, but I see in the background terminal the following errors whe...

Re: Gracefully shutdown RPi without ssh access

Thanks for the link! However, being a newbie, I am a bit confused...

The button should - I think - trigger some kind of function that tells the RPi to shutdown (something like sudo shutdown -h now). However, how does it do this if it's just connected to two GPIO inputs?

Thanks!

Gracefully shutdown RPi without ssh access

Hi, I am using a Raspberry Pi Model A+ to do some prototyping. To this end, I connect my RPi to my PC using an ethernet cable. The idea is that I login using SSH. However, sometimes, my RPi does not become visible through SSH and I have to reboot the RPi. Often however when I do this, the whole file...

Re: Send pictures from Raspberry to smartphone over bluetoot

Thanks for the suggestion! Sadly I only have an iPhone... Furthermore, I was looking if there was any information available to create an app that would be able to communicate with a Raspberry Pi module through bluetooth. I did manage to pair my Raspberry Pi to my iPhone. It was easier than I anticip...

Send pictures from Raspberry to smartphone over bluetooth

Hi there! I wonder if it is possible for a Raspberry Pi to send files to an iPhone or Android Smartphone over Bluetooth. I would like to send pictures I took with the PiCamera to my phone, but am unsure where to start... Will this require interaction from the user, or would it in practice be feasibl...

Re: Circular Stream seems not to work

Wow :-) I found the answer to my darkest dreams :D Apparently, the camera has to have a resolution set. Namely, the CircularIO buffer is sized not based on the amount of seconds I specify, but using the resolution! If I set the resolution to some high value (eg Full HD), than it only records a few s...

Re: Check if GPIO board is broken

Thanks a lot! It seems that this was some weird issue that now has solved itself. The testing at least could assure me that the GPIO was still functioning properly.

Thanks!

Re: Circular Stream seems not to work

I check the buffer simply by using a smartphone's timer. The video records the timer. As I set the circular video to 10 sec, I should at most have 10 seconds in the past of video. However, it was even worse that I thought. The circular video does not work at all, as it just flushes the entire video ...

Re: Check if GPIO board is broken

Thanks! I have done the following checks: 1) Used multiple different buttons 2) Used multiple different breadboard 3) Exchanged the wires 4) Checked the wiring 5) Used different pins 6) Inserted a LED on pin 23 and ground and tried to light it (did not work) 7) Checked for physical damage (none foun...

Check if GPIO board is broken

Hey! I have connected a button to the GPIO board of the RPi (Model B). Up until yesterday, it seemed to work quite well. However, since today, the button is not reacting anymore. I simply connected the button to ground and pin 17, and used a tutorial to check if it's being pressed. As it worked befo...

Circular Stream seems not to work

Hi! I am having a strange problem with the Pi Camera. My little program does the following: The camera uses PiCameraCircularIO to continuously record 20 sec Once I click a button, the previous 20 seconds will be saved to a file on the flash drive After that, the circular IO continues. If I would cli...

Re: Write recorded video to RAM

I did not yet look into the feature set of the camera module of the Raspberry Pi...

You mean to say that it includes buffering of about the last 10-20 sec of recorded video? If so, this would simplify the prototyping significantly :-)
