Libfap is a C port of the Ham::APRS::FAP Finnish APRS Parser perl module. As the original Perl code, libfap parses normal, mic-e and compressed location packets, NMEA location packets, objects, items, messages, telemetry and most weather packets. More information on HAM::APRS::FAP is available at http://search.cpan.org/dist/Ham-APRS-FAP/
- libfap version >= 1.4 (http://www.pakettiradio.net/libfap/)
Simple program that decodes the APRS-IS feed (omitting errors):
func main() {
defer fap.Cleanup()
conn, _ := net.Dial("tcp", "rotate.aprs.net:23")
fmt.Fprintf(conn, "user N0CALL pass -1 vers goAPRS 0.00\r\n")
reader := bufio.NewReader(conn)
for {
line, err := reader.ReadString('\n')
if err == io.EOF {
break
}
packet, _ := fap.ParseAprs(line, false)
fmt.Println(packet)
}
}
- wx_report
- telemetry
- capabilities
- tests
- ++
The parser (Ham::APRS::FAP) has been originally written by Tapio Sokura, OH2KKU and Heikki Hannikainen, OH7JZB. It has been ported to C by Tapio Aaltonen, OH2GVE and wrapped in go by Martin Hebnes Pedersen, LA5NTA.
