Re: SPI Problem for DAC 8563

I attached the image I can't read that, but it doesn't look like a proper error message to me... IMHO it would be much clearer if you use print statements that output relevant state information. Your screen dump shows 2 values and that's it. There is no info at all about other (relevant) variables,...

Re: build a specific version of raspberry pi

I was just wondering what version of raspbian does it build The current one. It's actually not a tool to create a specific 'version of Raspbian' but it's meant to create an image with the current state of Raspbian (and additional tools) using a user-defined configuration (by default that's the RPF ...

Re: How do you delete the "work" directories after a build?

Yes, I could have provided a few more details. I thought it was enough though. Back on point, do you have any suggestions? Is there a pi-gen specific forum? There is no need for a specific forum. You just need to provide more information in your post. Keep in mind that Raspbian (the section you're ...

Re: How do you delete the "work" directories after a build?

This (again) shows how important it is to give as many details as possible. Someone wanting to help has to assume several things here, starting with what tool you use to build an image (I assume it's pi-gen) If it's pi-gen one has to assume it's the standard build and not the docker version (as this...

192.168.1.1 should be your routers IP address.
Not necessarily. Eg a very large percentage of home routers in the UK have an IP address of 192.168.1.254.
It varies. I've never seen a .254 router, mostly .1 but the subnet changes.
BT home hubs use it

Only if you use RealVNC server and viewer. It has a feature to capture the video that bypasses the framebuffer (such as the pi camera preview)

Re: How do you delete the "work" directories after a build?

I am unable to due to privileges. You need admin privileges; use 'sudo' From the command line use e.g. sudo rm -rf name-of-the-directory This will recursively remove the content of that directory. Be careful when you use this; it's easy to delete something that is essential for keeping the Pi running

Re: Camera won't preview

Are you using a monitor directly connected to the Pi or o you use remote access software (VNC)? By default the preview only shows up on a local screen. What command did you try? Did you check out the raspistill / raspivid documentation? https://www.raspberrypi.org/documentation/usage/camera/raspicam...

Re: Difference between these 3.5" HDMI displays?
