| |
Hi,
I just wrote a small driver (actually just a line in do_timer() and a new entry to the procfs) for my selfmade DCF77 receiver (DCF77 is the official German time signal broacast at 77.5kHz).
My hardware is very simple and cheap; it just demodulates the signal and feeds it to a joystick button input. The joystick button register is sampled with each timer tick and written to a ringbuffer. The buffer is examined and converted to readable output just like that of "date" each time /proc/dcf77 is read. I use this to set the time using "date" (funnily date is stupid enough not to understand its own output as input).
If anyone's interested I could provide both hardware and software documentation.
Maxi
