hello ,
I am using UART in PIC 24FJ128GA010 for receing data from Hyperterminal & displaying on LCD. After 4th character Receive Buffer overflows & U2STAbits.OERR becomes set. I am detecting OERR bit, then clears the same & transfering 5th character onwords... but program is not working.. it overflows after 5th character... Please suggest any solution . I m herewith giving my code....
/****************************************
void lcdCmd(int);
void lcdWrite(char *);
void delay(int);
#define RS PORTBbits.RB15
#define RW PORTDbits.RD5
#define EN PORTDbits.RD4
main()
{
const unsigned char MyString[15]; //
RS232Init(); //This function has to be defined by me to get data (UART in receive mode)
LCDInit();
int i = 0;
while(1)
{
MyString[i] = GetRS232();
while(MyString[i]!=0)
{
lcdWrite(MyString);
i++;
MyString[i] = GetRS232();
delay(500);
while(U2STAbits.OERR)
{
U2STAbits.OERR=0;
U2RXREG=0X0000;
delay(500);
MyString[i] = GetRS232();
}
}
i=0;
}
}
/************************************************
#include <p24FJ128GA010.h>
RS232Init()
{
char p;
TRISFbits.TRISF5 = 0;
U2MODE = 0x0800;
U2BRG = 0x0019; //0x26;
U2MODEbits.UARTEN = 1;
U2STAbits.UTXEN = 0;
}
char GetRS232()
{
char P;
while(!U2STAbits.RIDLE);
{
P=U2RXREG;
delay(500);
}
return (P);
}
thanks in advance..
