car engine start thru sms

[ECE200407406006]

mga sir, baka may comments po kayo on how to improve/increase efficiency ng program po namin.. ang project po namin is itetext yung car para istart ang engine.. owner type jeep ang pinagkabitan namin.. we used the IRC slimboard, GSM module, both form e-gizmo, and switchboard na DIY para intranslate yung 3.3V output ng zilog to 5v para maswitch ang 6V relay.. eto po ang code.. nakuha ko po yung pinakalogic nung program from a code na pinost po ni sir efilaypee, not sure kung kasama sa nabura yung thread na yun.. inedit ku lang to fit ours.. thanks ulit sir..  eto po yung code namin..

yan na muna sa ngayon. marami pang pwedeng ma enhance sa code... btw, baka may mga unintentional akong na erase kasi panay copy cut paste ang ginawa ko hehehe...

[xueyuanlu]

Mga mams and sirs, ask ko lang po, tinatry ko po intindihin yung code, para matuto ng AT command embedding sa Zilog. Bakit po may line na ganito:

if(TESTING){select_port(_UART1); printf("%s", msg); }

dun sa code, eh di ba po nakadefine yung TESTING sa "1" so ibig sabihin lagi lang itong line na ito maeexecute? So bat pa po nilagyan ng IF na condition kung lagi rin naman po siyang maeexecute? thanks po. salamat po ng marami

[kelvinblank]

san nyo po ikakabit sa owner jeep yan? ung amin kasi sa kotse sa ignition wire namin kinabit ung output ng relay

[xueyuanlu]

^^ ako po ba yung tinatanong niyo? yung sa akin po kasi concern ko lang yung sending, iba yung application ko hindi car engine start, sa ibang sensor nakakabit. wala po akong makitang resources sa internet regarding C-Embedded AT Commands, puro examples lang. so I am trying to dissect and analyze bawat code na makikita ko. sorry po kung off-topic yung post ko, pero medyo related naman hehe..

anyway sir masasagot niyo po ba question ko bakit

if(TESTING){select_port(_UART1); printf("%s", msg); } 

ganito yung code? kasi TESTING was defined, #define TESTING 1
so meaning, before hand "1" na ang value ng testing. so ibig sabihin etong line na to laging
maeexecute pag natagpuan ng compiler. bakit po nilagyan pa ng condition na "IF" kung lagi rin
naman siyang eexecute? sir patulong po ha.. salamat po sa pag-reply

[0b00000111]

most commonly ginagamit yang ganyang style sa debugging at testing stage...

for example tapos na ang testing nya, rather than commenting all the lines he can just do this

#define TESTING 0

then di na mageexecute yung if statement.

although this method is commonly used with conditional compilation directive #if/#endif.

[xueyuanlu]

^ah ok thank you po, mam/sir.

[xueyuanlu]

isa pa po pala, yung line po ba na ito (interrupt parts):


#pragma interrupt
void read_uart0(void){
   if (U0STAT0 & 0x80) msg[msg_index++]=U0RXD;
}

void initial_uart0(void){
   DI();
   SET_VECTOR(UART0_RX, read_uart0);
   IRQ0ENH |= 0x10;
   IRQ0ENL |= 0x10;
   IRQ0 &= ~0x10;
   U0CTL1 &= ~0x02;
   EI();
}

ang may kinalaman para magfunction yung line na:

strstr(msg,"ERROR")

kasi I am wondering, saan manggagaling yung laman nung "msg" na variable. salamat po.

pati po ano po ibig sabihin nung U0STAT0 and U0RXD. halos lahat po kasi ng sending SMS codes na nakita ko may ganyan.

[ΔЅịMø]

mga sir, working na poh ba ito?
