SIM300使用PIC16f在Mikroc中发送SMS

Question

我一直在尝试使用SIM300模块发送SMS。尽管使用超级终端尝试模块时工作正常，但我无法使用PIC发送短信。

下面是我试图代码（LCD还包括（LCD工作正常））：

编程：MIKROC
控制器：PIC16F877A
模块：SIM300

sbit LCD_RS at RB4_bit; 
sbit LCD_EN at RB5_bit; 
sbit LCD_D7 at RB3_bit; 
sbit LCD_D6 at RB2_bit; 
sbit LCD_D5 at RB1_bit; 
sbit LCD_D4 at RB0_bit; 

// Pin direction 

sbit LCD_RS_Direction at TRISB4_bit; 
sbit LCD_EN_Direction at TRISB5_bit; 
sbit LCD_D7_Direction at TRISB3_bit; 
sbit LCD_D6_Direction at TRISB2_bit; 
sbit LCD_D5_Direction at TRISB1_bit; 
sbit LCD_D4_Direction at TRISB0_bit; 

void main(){ 
//CMCON = 7;      //Disable Comparators 
Lcd_Init();      // Initialize LCD 
UART1_init(9600);     //Initiate baud rate to 9600 
Delay_ms(500);      //Delay 
UART1_Write_Text("AT+CMGF=1");  //Write "AT+CMGF=1" 
UART1_Write(0x0D);     // mean (ENTER) 
Delay_ms(500);      //Delay 
UART1_Write_Text("AT+CMGS=");  //Write "AT+CMGS=" 
UART1_Write(0x22);     //Write (") 
UART1_Write_Text("9449869619");  //Number SMS send to 
UART1_Write(0x22);     //Write (") 
UART1_Write(0x0D);     // mean (ENTER) 
Delay_ms(500);      //Delay 
UART1_Write_Text("WELCOME"); 
UART1_Write(0x0D);  //Words to be sent 
UART1_Write(0x1A); 
       //Write "ctrl+z" 
Delay_ms(500);      //Delay 
Lcd_Out(1,1,"MSG SENT SUCESSFULLY"); // Write text in first row 

} 

Answer 1

您应该尝试

Uart1_Write_Text（“AT + CMGF = 1 \ r”）;

因为“\ r”代表“输入”或“返回”，有时“0x0D”在微控制器中不起作用。

我一直在使用它，它适用于我。
