c code library for connecting a UBLOX GPS to an AVR MCU

[h.v]

hi
i have successfully connected a UBLOX GPS to an AVR MCU with a simple program in CodevisionAVR, i can read both NMEA and UBX protocol messages in a simple program and then display the raw data on a LCD connected to MCU.

i just need the UBX protocol not NMEA !
I have read the protocol specification at:**broken link removed**

But it seems somehow difficult to filter and parse its messages
i am trying to write a function to do that in CodevisionAVR.!!

Does anyone have c code library for that?

is there a way that I can get the sample code from the ublox gps. I am trying to pull the proprietary string from ubx, 04. the time of week and week number. thank you
