terminal I/O on msp430F2417 - rupesh vishwakarma - Aug 12 1:15:34 2009
Hi,
I want just a simple programm which will take input from hyperterminal and =
print the same on hyperterminal ,
I can print the characters easly by the following code
void kputchar(char TXchar)
{=A0=A0=20
=A0
=A0 while(!(IFG2 & UCA0TXIFG))
=A0=A0=A0=A0=A0=A0 {
=A0=A0=A0=A0=A0=A0=A0=A0=20
=A0=A0=A0=A0=A0=A0=A0 }
=A0=A0=A0=A0=A0=A0=A0=A0=A0=20
=A0// wait for TX register to be empty //
=A0=A0=A0 UCA0TXBUF =3D TXchar;=A0
}=A0
it prints the characters on terminal
what should I do to get characters from hyper terminal just like scanf or g=
etchar to get characters from hyperterminal I tried to enable rx interrupt =
by
void UARTset(void) //Uses USCI_A0
{
=A0 P3SEL |=3D BIT4 + BIT5;=A0/* P3.4, P3.5 UART mode */
=A0 P3DIR |=3D BIT4;=A0=A0=A0/* P3.4 - output */

=A0
=A0__bis_SR_register(GIE);=A0=A0=A0=A0=A0=A0 // Enter LPM0, interrupts enab=

=A0}
but the code never goes to RX interrupt handler=20
#pragma vector =3D USCIAB0RX_VECTOR
__interrupt void RXhandler (void)
{
=A0=A0=A0=A0=A0 if (IFG2 & UCA0RXIFG)
=A0=A0 {
=A0=A0=A0=A0=A0=A0 char rx=3DUCA0RXBUF;
=A0=A0 kputchar(rx);
=A0=A0=20
=A0=A0 }
code even does not jumps to rx handler so how can I get characters from ter=
minal??

Rupesh,
Why are you starting multiple threads with the same question, and even
attempting to hijack other threads? Why should anyone take the time to
help you if you don't respond to the help?
With your additional emails, you still do not include the MSP430
device you are using in your design. Please include that when starting
a thread with a new question. A lot of expertise found in this group
is applicable across the entire MSP430 family, but some is more
specific to particular devices.
The fact that your kputchar(char) routine works suggests that your
UART is configured correctly, at least as far as baud rate and
modulation is concerned. It doesn't, however, use interrupts, so that
suggests that there is something wrong with how you're handling
interrupts. Following that train of thought, I notice that it seems
that the interrupt vector you've included is not the ISR corresponding
to the USCI interface (USCI_A0) you use in kputchar(char) or the RX
interrupt you enable in UART_set( ). Do you have another ISR that you
haven't included in this email, or is that the problem?
