I fact the previous example was just for demonstration,but when I tried
while(!(U0IFG & UTXIFG)) I experienced also garbage on terminal input from
usart0.
I changed to while(!(U0CTL & TXEPT)) what looks to be more accurate, but I
haven't tested.
What ddo You think ! Is it better?
I can not use interrupts
