You may use interrupt for reading message indications from GSM module.
Use UART_Read() to read data only after receiving data. You can make sure that the data is received, by using UART_Data_Ready().Try using following functions.
void gsmInit() { UART1_Init(9600); Delay_ms(200); UART1_Write_Text("ATE0\r"); // ECHO OFF Delay_ms(100); UART1_Write_Text("AT+CMGF=1\r"); // Text Mode Delay_ms(100); UART1_Write_Text("AT+CNMI=2,0,0,0,0\r"); Delay_ms(100); } void gsmSendSMS(char mobile[11], char message[10]) { UART1_Write_Text("AT+CMGS=\""); UART1_Write_Text(mobile); UART1_Write_Text("\"\r"); UART1_Write_Text(message); UART1_Write_Text(26); Delay_ms(100); }You should use UART1_Read_Text() or UART1_Read() without any delays…
Eg:for(i=0;i<34;) { if(UART1_Data_Ready()) { s[i] = UART1_Read(); i++; } } // All further data processing or LCD commands should be here..Yes, ofcourse.
HC06 is a 3.3V device. So power it from a 3.3v supply. Make grounds of both supply common.
You should reduce the 5V TX output of PIC to 3.3V by using voltage divider resistors before connecting to RX of HC06. You can use a 10K and 4.7K for that.
3.3V TX output of HC06 can be directly connected to PIC RX. PIC will detect 3.3V as HIGH level.
For MPLAB you can use the following link.
Generating PWM with PIC Microcontroller – MPLAB Hi-Tech C
That code is working fine for me.
MikroC libraries are working fine without any problem. Try the following link.
If you are using MikroC, please use the HELP section to find details of SoftUART library. It is very easy to use.
Yes, you can. You have two options.
- Multiplex UART using IC 74HC4052
- Using Software UART, which means that you can program any GPIO pin of PIC as UART. MikroC Pro provides built in library for that.
MikroC functions are 100% working..
You can use the following MPLAB XC8 tutorial to write your own functions.
Hello
I don’t understand what you are saying. If you are talking about GSM modem,, its data is already ASCII, no need to make any change.
