Hello All,
I started to work on lpc2148 with xbee series 2.
On the transmitting side i am using lpc2148 with xbee coordinator in API mode,
and Rx side i am using xbee on Shield in router AT mode.
I want XBee to activate a D3 pin, which could be used to turn on relay on Rx side
API frame format as below code using c program .
#define Delimeter 0x7E
oid Init_UART1(void) //This function setups UART1
{
unsigned int Baud16;
U1LCR = 0x83; // DLAB = 1
Baud16 = (Fpclk / 16) / UART_BPS;
U1DLM = Baud16 / 256;
U1DLL = Baud16 % 256;
U1LCR = 0x03;
}
void main() {
Init_UART1();
LED1_ON();
setRemoteState(0x5);//AD3 config DOUT HIGH
Delay(25);
LED1_OFF();
setRemoteState(0x4);//AD3 config DOUT LOW
Delay(25);
void setRemoteState (char value) {
UART1_Write(Delimeter);//start byte
UART1_Write(0);//high part of length
UART1_Write(0X10);//low part of length
UART1_Write(0X17);//remote AT command
UART1_Write(0X0);//frame id 0 for no reply
UART1_Write(0X0);
UART1_Write(0X0);
UART1_Write(0X0);
UART1_Write(0X0);
UART1_Write(0X0);
UART1_Write(0X0);
UART1_Write(0XFF);// broadcast
UART1_Write(0XFF);// broadcast
UART1_Write(0XFF);
UART1_Write(0XFE);
UART1_Write(0X02);//apply changes immediately on remote
UART1_Write('D');//writing on AD3 pin
UART1_Write('3');
UART1_Write(value);
sum = 0x17 + 0xFF + 0xFF + 0xFF + 0xFE + 0x02 + 'D' + '3' + value;
UART1_Write(0xFF - (0xFF & sum));//checksum
Delay(25);
}
}
i am not able to get any communication or data on my Rx side.
Please guide on this point...
This program is working fine with arduino using Serial.write Function.
Regards,
Vijay
