hello
my objective is to get the 1PPS signal to synchronize a 10 Mhz VCXO
for the moment I spend hours to understand how to "speak" with this GPS Receiver
I got a lot of sotware .. TSIP104 seems the best one
for the moment the 1 PPS is a 0,5 PPS ! with a very short Positive pulse (0,2µS)
I have done a very big program to monitor it !

essai:
if PPS = 0 then goto essai
high ledrougeause 100: low ledrougeause 100
goto essai

I works ! but not very wonderfull, may be the 12F675 int clock has problem
to sample the 3,3 volts signal (1PPS from GPS) because the flashing is not OK all the time
I see in the GPS datasheet that PPS signal can be setted with many options
One could be good for me "option that say that PPS signal will be avalaible if the receiver
see at least 3 sats" I didn't find how to set up this condition
eitheir in NMEA or TSIP mode ..
If "somebody" has done with this PPS signal, any input will be appreciated
thanks
Francois
