Wouldn't help, the problem is further up, and a lower body transplant could be risky, I might end up with boobs or something! Hmmm! thinking on it would that be So bad?

Well typing can be difficult when you only have limited use of your hands. I'll try to do better next time.

I believe you were looking for “frightening” not “fightening".

Why oh why are you bit banging this when the MSP430 has an extremely simple UART in hardware. Are interrupts that fightening?

Hello, I'm trying to communicate with my RF module through UART interface. However, I get many errors even with low load. I suspect that I have an issue with the way that I configure the clock or the UART.
Basically, for the UART functionality I use http://glitovsky.com/blog/?p=300
(I configured the connection as 8N1 at 115200).
The clock configuration below is used with MCLK = 25 MHz ( when I use it with MCLK=16 MHz I cannot communicate with the UART module at all ) .
P5SEL |= 0x0C;
/* Select REF0 for FLL reference. */
UCSCTL3 &= ~SELREF_7;
UCSCTL3 |= SELREF_2;
/* Set ACLK to use REF0CLK.
* Set SMCLK to use the DCO.
*/
UCSCTL4 &= ~SELA_7 & ~SELS_7 & ~SELM_7;
UCSCTL4 |= SELA_2 | SELS_4 | SELM_4;
/* Initialize FLL. */
Init_FLL_Settle(mclk/1000L, mclk/32768);
XT2_Start(XT2DRIVE_0);
UCSCTL4 &= ~SELA_7;
UCSCTL4 |= SELA_2;
UCSCTL8 |= SMCLKREQEN | MCLKREQEN | ACLKREQEN;
/* Enable interrupt for TBCCR0. */
TBCCTL0 = CCIE;
/* Number of ticks per millisecond. */
clock.aclk = 32768;
clock.ticks_per_interrupt = clock.aclk / 1000;
TBCCR0 = clock.ticks_per_interrupt;
/* Use ACLK, set timer to up-count mode, and start timer at zero. */
TBCTL = TBSSEL_1 | MC_2 | TBCLR;
/* Enable interrupts. */
__bis_SR_register(GIE);
Thanks,
Mike
