Hi, I wanted to write a simple program that doesn’t use interrupts or check any of the possible error flags, but that shows a simple UART application for receiving data. This is a part of the code I wrote.
int uart0Getch(void)
{
if (LPC_UART->LSR & LSR_RDR) // check if character is available
{ return LPC_UART->RBR; // return character
}
return -1;
#include "includes.h"
#include "uart.h"
int value;
extern int main( void )
system_init();
screen1[0]='a';
screen1[1]='b';
screen1[2]='c';
while(1)
//KeyScanProc(buf,screen1);
if ((value = uart0Getch()) >= 0)
send_to_uart(screen1,3);
Yes, in fact I just ran the program with the flush function and the output
was something like: "HEL W". Thank you very much for your help!!! It has
been very useful
