Reading a non-null terminated input at serial? - mbed

Question

I am working with mbed, the LPC1768. The serial input to the mbed is a unsigned character array which is not null-terminated. I don't get anything with getc(), how to get the input?

Answer 1

the null character is 0 so if you need get it u can using a Buffer Counter or a ovf variable to detect received a character!!
Config your UART0,1 by this Setting:
comment UART0 or UART1 if not use it!
so u can select UARTs with #define in: option->C/C++->Define:__UART0 or __UART1
void SER_Init (void) {
#ifdef __UART0 /* UART0 */
LPC_SC->PCONP |= ((1 << 3) | (1 << 15)); /* enable power to UART0 & IOCON */
LPC_PINCON->PINSEL0 |= (1 << 4); /* Pin P0.2 used as TXD0 */
LPC_PINCON->PINSEL0 |= (1 << 6); /* Pin P0.3 used as RXD0 */
#else /* UART1 */
LPC_SC->PCONP |= ((1 << 4) | (1 << 15)); /* enable power to UART1 & IOCON */
LPC_PINCON->PINSEL4 |= (2 << 0); /* Pin P2.0 used as TXD1 */
LPC_PINCON->PINSEL4 |= (2 << 2); /* Pin P2.1 used as RXD1 */
#endif
UART->LCR = 0x83; /* 8 bits, no Parity, 1 Stop bit */
UART->DLL = 9; /* 115200 Baud Rate # 25.0 MHZ PCLK*/
UART->FDR = 0x21; /* FR 1,507, DIVADDVAL=1, MULVAL=2 */
UART->DLM = 0; /* High divisor latch = 0 */
UART->LCR = 0x03; /* DLAB = 0 */
}
------> and use this func. for Get Character:
/*----------------------------------------------------------------------------
Read character from Serial Port (blocking read)
*----------------------------------------------------------------------------*/
int SER_GetChar (void) {
while (!(UART0->LSR & 0x01));
return (UART0->RBR);
}
