Re: Pi Camera - Minimum Distance from Object

@goldberg Thank you for your reply, that is interesting. I understand that your camera is 110mm from the meter. I really need to get a lot closer than that though and I am hoping to mount the camera on the inside of the plastic lid that hinges down at the front of the Meter box. With the position th...

Re: Programming an i2C interface in Python

@bensimmo
Yes, that is the command to turn them ALL on but I am just trying to turn the White ones on using 0x5a and this command works perfectly from the Terminal. The 0xff doesn't work either from the Python script but it is fine from the Terminal.

Re: Programming an i2C interface in Python

Sorry, to be a nuisance but I cannot get the simplest of parts to work. I decided to start with the smbus option. when I first tried the 'write_byte_data' command, it reported that 'write_byte_data' is not defined, so I added the 'bus = smbus.SMBus(1)' and changed 'write_byte_data' to 'bus.write_byt...

Programming an i2C interface in Python

I have a product named 'Bright Pi' that consists of a small board with 8 IR LED's and 4 white LED's that mounts in front of the Pi Camera. It has an i2C interface and I have got it working perfectly using sudo commands from the terminal. I now want to incorporate it into a Python program but I have ...

Pi Camera - Minimum Distance from Object

I understand that the lens on the Pi Camera can be rotated to ensure that close up items can remain in focus. I could do to be able to use the camera to take a picture of an electric meter reading, so the camera needs to be about 25mm away. Does anyone know if a distance this short is possible. (I d...

Re: GPIO.setmode - Error Message

So it seems the cleanup is within the for loop. It does one pass where it captures a frame, sleeps a bit, calls cleanup, then tries the next pass through the for loop and fails because you have undefined the setup of the gpio pins you have used? Yes, I have removed the 4 spaces before the cleanup c...

Text overlaying 'Welcome to Pixel' flash screen

A few days ago, I successfully loaded the latest version of Raspbian, with VNC and Pixel. Today though, the 'Welcome to Pixel' Flash screen comes up but is then overwritten with text, in a style similar to the Terminal but not in a separate screen, just overlayed. The final line of the text says: SS...

I didn't actually understand this step, so I thought I would try the suggestion of getting the Micro SD card working in another Pi and swapping over and come back with more questions if it didn't work - fortunately it did, Thanks anyway.

Thank you for your suggestion. I tried what you said and I have now got it working, so loading the Pi zero with a card that been set up on a Pi 3, has solved the issue.
