8051 gps
GPS receiver sends a lot of ASCII strings.
For example:
$GPGLL,2138.0754,S,11218.8060,E,202328,A*33
The usefull information is:
2138.0754 S(south) and 11218.8060 E(east)
Using 8051 serial port interrupt, what is the most efficient way of extracting this information and ignoring all other strings (hundreds of useless characters)
Thanks
