| Interfacing RTC and GSM |

hi, I am tying to interface RTC DS1307 and GSM modem to control electrical devices. Both are working independently but not when integrated.
Here is my code.
| Code: |
#include <16F877A.h>
#define max 65534
#device *=16
#device adc=10
#include"pic.h"

#use delay(clock=20000000)
#use rs232(baud=9600,parity=N,xmit=PIN_C6,rcv=PIN_C7,bits=8)
#use i2c(Master,Slow,sda=PIN_C4,scl=PIN_C3)
#include "ds1307.c"
#define h_sw rc0
#define m_sw rc1
#define s_sw rc2
#define set_sw

I am using the compiler CCS 3.36
Anyone please check these? |

Both RTC and GSM works independently.
But GSM is not working, means messages are not received by the controller. I tried to use interrupt but, not enough space. |

couple of comments...
1) whenever you use the hardware UART, be sure to add 'errors' to the uses rs232(....) code !
2) NEVER enable any interrupt without having an ISR for it ! You enable INT_RDA but I can't se the 'handler' ( ISR) for it. Program will crash...
3) your timesetting code is very similar,so codespace could be saved by creating a common function and calling it instead of all the inline code you have.
4) you've coded the ldf() function to return a float,but the ADC will only return a 10bit integer.
5) go(xx) means what ???? either I can't see it or it's missing ? |
