GPS Seriale con output non ASCII

-

buongiorno, ho smontato da un antifurto viasat il circuito del ricevitore gps, l'ho alimentato, ho collegato l'uscita ad un convertitore usb-ttl e mi sono connesso in seriale con il computer per tentare di sniffarne il traffico, l'output è una cosa del tipo:

code: [select]
isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ.......isa.rÛ

oppure

code: [select]
|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|..@....isa.\¡..@....isa.\¡..@....isa.\¡..@....isa.\¡..@....isa.\¡.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°|.......isa.°

trasmessa in continuo ed ogni tanto una scritta "disabled". ho provato inserire una not pensando che il codice fosse negato ma nulla da fare, ho allora inserito due porte not in modo da stabilizzare solamente le tensioni ma ancora niente, sempre lo stesso codice, cosa sbaglio? il modulo è un sgm5610 o anche venduto come mkn5610

solitamente quel genere di apparati usa ricevitori gps custom con out in formato binario tramite protocollo proprietario, non forniscono le classiche sentenze nmea.

hey everyone, i'm trying compile simple code on rpi3 using geany. code written using code::blocks on windows , working without problem. errors i'm getting are: untitled.c:33:5: error: ‘for’ loop initial declarations allowed in c99 or c11 mode , untitled.c:33:5: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 compile code understand code not problem way i'm compiling it. can give me advice? you need add 1 of suggested options compile command configured in geany, in menu.. build -> set build commands add "-std=c99" after "gcc" in compile , build boxes. (i'm looking on mint pc expect version on pi same). petero raspberrypi
