SMS CONTROLLER USING SE T230 with PIC16F877A that control relays

[chitobuknoy18]

can anyone help my project regarding sms controller using SE t230 with pic16f877a that control relays (8 relays) here is my code below:

#define TRIGGER PORTD.F1 // set porta/f5 as output
#define DATA PORTA.F4 // set data to c922 for keypad decoding

unsigned int index=0,count=0,address=0,addrLength=247,inbox=0,intFlag=0;
unsigned short intTimer;
unsigned char msg[30], mess[20];

Check this program on proteus software to confirm if it is working fine...

sir were is the you code you said sir so that i can try it

---------- Post added at 15:12 ---------- Previous post was at 15:11 ----------

ive already try it but still no effects i cant understand what is the problem

 

[ckshivaram]

compile your code and try if your serial communication is working
it will follow your code and you should see the AT commands and response...

 

[chitobuknoy18]

this is my simulation i think there is something wrong with it

 

[chitobuknoy18]

i dont have enough knowledge in programming pic that is one of my problem

 

[ckshivaram]

this thread and discussion should help you in programming the PIC
