Re: BMP280, testers needed

What "virtual" files do you find in /sys/bus/iio/devices/iio:device0/* on your system?

You may be able to "echo" some values into the controls for your sensor using those.

Re: How to add files on the SD card with the ISO on it?

Not easily, because Windows applies the "not invented here" rule to the Linux filesystems and won't recognise them or mount them for normal use. Move files from Windows to Linux using a USB stick, or a USB hard disk. Or make your Raspberry run a SAMBA/CIFS server and mount that shared filesystem on ...

Re: My Zero W died when I plugged in a hub to the OTG adapter.

It's more likely that you've corrupted your SDCard.

Grab a factory fresh card, write Raspbian 2018-10-09 onto it with Etcher. Try booting that. If that works you can use a USB SDCard reader to repair the broken filesystems on your original SDCard.

Re: Cannot login to my pi via Putty...

Have you enabled ssh?

Pull the plug, pull the SDCard. Insert the SDCard in your Windows system and create F:\ssh.txt on it. Eject it safely, put it back in your RPi. Boot the RPi and it will automagically enable ssh for you.

Why not use the kernel driver? Add dtoverlay=i2c-sensor,bmp280 to /boot/config.txt Your BMP280 will then appear as /sys/bus/iio/devices/iio:device0 with various "virtual" files in there to give you the readings from the sensor.
