I/O timer module function in MSP430

[TERRYWU3]

Dear expert,

I am new user to use MSP430(F2013) . It has many module function described on
IO like: TA0~2、CA0~x .

I want to know if I need to decode rs232 signal . I want to use timer to implement.


1.Do I need to select IO which have TAx function?
2.If question 1 is "yes" , then what's different that IO with TA0 and with TA1 ?
What does I need to modify the relative register setting when use TA0 change
to TA1?

Very very thanks ~

Hi

It depend what member of MSP430 are you using whether it include a hardware UART you will need to set the UART on and set the corresponding I/O as well

Whether the MSP430 dosen't have a UART module then you will need to use the TIMER as your time base and some I\O as input and output

There are many examples how to do it both ways - see TI site for MSP430

All the best
