Sometime ago pleople here talked about using the PRU´s (two cores with
predictable timing) inside the Beaglebone´s main chip to make time
measurements. Today I found this article that points to more data about
programming the PRUs, even in C:

Ulrich kept this to himself until about six months later in an email explaining

In respect for Ulrich's wishes I kept this news off the list.
Ulrich's Obituary indicates that one parent, his in-laws and siblings as we

I remember a few discussions over the last few years about building a
microcontroller (PIC, Arduino, MPS430, whatever floats your boat) based
IRIG generator. Did anyone ever get one working?
Thanks!

I bought a receiver labelled as Conexant Jupiter-T TU60-D120-041. I
constructed an RS-232 serial interface, a 1 Pulse per Second LED and a
10 kHz test point. After a few minutes the 1 pulse per second LED syncs
up with the audible ticks on WWV so it seems that the receiver is
receiving the sa
