Very interesting test!

I bought a PiFace RTC and I'm trying it on a Raspberry Pi 2 Model B. I followed the many guides I found on the internet, but I'm still having problem with the date: when I reboot, the system time is always set to Jan 1, 1970! It seems to be in a reset condition.

After the execution of the .sh script as written in the PiFace RTC user guide, I set the actual date with "sudo date -s "12 jan 2016 10:30:00",

set the i2c module from raspi-config.

The device is correctly seen at the right address 0x6F, and I really can't understand what I'm doing wrong!

Any idea would be appreciated!
Thanks,

Andrea.

I concur with Mark - great write up! I'm curious - in you picture it looks as though the RTC shim is covering the processor with very little air gap between the two. Would you say that there is sufficient space for even a small heat sink to be placed on the processor and still have room for the RTC? Maybe you answer this in the video, but with metered internet connectivity I'm afraid 23 minute videos are not for me... But thanks for the info on this device!

Now this is a sweet bit of kit!

An excellent write up Alexander. Haven't watched the video yet, will do later. Looking forward to seeing other accessories on test.
