Hi to everyone in this post!
As a novice user on the USART (and without any knowledge on
Assembler) I was trying to implement an AN from IAR on the Workbench
which is intented to provide a "circular buffer for the serial
interface" in C code.
When declaring the variables for the buffer it states the following:
sfrb URXBUF = 0x76; // receive register
sfrb UTXBUF = 0x77; // transmit register
The compiler says it cand resolve sfrb. I have checked the TI User
Guide and I found that the SFR states for Special Fuction Register,
but I couln't figure it out how to resolve it.
I would like to ask anybode who can give me a hand about a proper way
to define the above.
Also, I have had trouble init the USART to be used with a XTAL
running at 8Mhz and connected to a MAX232 (I'm using an MSP430F133).
My goal is to use it a an speed above 19200 and 8N1. Has anybody an
example of how to set it up correctly in C for the IAR compiler?
Thank you for any light on it. I appreciate your kind help.
Good luck to everyone.
