Dear all, I am new to LPC2378..Currently i am developing code for sending a character in serial port....Below i mentioned the code what i have written..but this is not working...i am using keil uvision3...Can anybody help me in this code????In my hardware DB 9 connectors rxd and txd are connected together(loopback test)
This is my code...
#include <LPC23xx.H> #include <stdio.h> void delay(int); int main (void) { PCONP |= (1<<3) /* power for uart 0 */ PINSEL0 |= 0x00000050; /* Enable TxD0 *//* Enable RxD0 */ U1LCR = 0x83; /* 8 bits, no Parity, 1 Stop bit */ U1DLM = 0x00; U1DLL = 0x78; /* 9600 Baud Rate @ 12MHz Clock */ U1FDR = 0xA3; U1LCR = 0x03; /* DLAB = 0 */ U0FCR = 0x81; while(1) { U1THR = 'A'; while (!(U1LSR && 0x40)); }
.
The program which i have done in rs 232 programing (LPC 2148)is as follows
FOR TRASNMITTING
void main() {; U0DLL=97; PINSELO=0X00000005; U0LCR=0X83; U0DLL=97; U0LCR=0X03; U0THR='A'; while(!(!(UOLSR&0x40)); while(1); }
. when debugging this code,the character 'A'is displayed on serial window iam also aware of U0RBR which is used for receving like
while(!(U0LSR&0X01)); data 3=UORBR;
