PiFace Real Time Clock utility available

[John Howie]

Hi everyone,

I just released on GitHub source for a utility that manipulates the PiFace Real Time Clock, available for the Raspberry Pi. I have tested it on FreeBSD 11.0-CURRENT, running on a Raspberry Pi Model B 2. It should work on a Raspberry Pi B (original), and it might even work on 10.2-RELEASE (it requires I2C bus support).

I will be doing some more testing and refining it in the coming days, but I invite anyone who wants to play around with it to do so. The repository is https://github.com/jhowie/FreeBSDPiFaceRTC.

Even if you do not have a PiFace RTC you might want to pull the code, and in particular the I2CRoutines.[ch] files, as they contain a simplified means of interacting with I2C devices. The code currently supports devices with only 256 bytes of addressable memory. I will correct that in a future release.

I will also be developing a Real Time Clock Device Driver for FreeBSD. I will release that later this year.

Regards,

John
