DS3231 I2C RTC and g_ether - cannot use both?

Hi, I've got a couple of cheap DS3231 real-time-clock add-ons which work over I2C: https://www.ebay.co.uk/itm//153061540451 After a considerable amount of trial and error, it would appear that these cannot be used at the same time as the USB gadget g_ether ethernet mode. Does anyone agree / disagree...

Hi folks. I'm trying to set a static IP in the 169.254.x.x range for USB OTG using g_ether (an ethernet connection using a micro USB cable from a Pi Zero to a PC).

Re: Raspbian NTP clock synchronisation- how often and where?

Thanks chaps.

Might have a look for a cheapo USB RTC. Problem is that the GPIO header is taken up with a Unicorn HAT so can't use a GPIO solution.

For example, no...

Re: I need to find out the IP address of a remote RPi3....?

It's Linux. There is always another way... If your goal is to be able to ping/ssh/connect to your machine from your local area network, then you can use Avahi, also known as Zeroconf and Bonjour. Your Raspberry Pi will need to be the only machine on the network with its hostname. By default the host...

As noted above, the internal clock is set to use UTC (which is mostly the same as GMT), and then the operating system is aware of what timezone it is in, and shows the correct time for that timezone, based on an offset from UTC. You can check and configure which timezone your system is set to, by go...
