msp430f2013 and RS232

Development Boards MicroMod

hello,

I have a great problem concerning msp430f2013 on the ez430 board…

I want to launch the example from texas instruments that returns a character which i send trough the terminal via rs232

I know I have to use a voltage converter (I use max3232c)…

but something is wrong… in the debugging mode i step through the code and I discovered that the uc gets what I have sent him but doesnt return anything… is there something wrong with the example code from texas instruments (i use the assembler example) or am I doing some mistakes??

can anyone help me with this?? :smiley:

Which sample code are you using for your echo program? Also, could you explain the need of the max3232c? I am trying to build a similar project, but hooking the MSP430 to a BlueSmirf bluetooth module (Acts as a wireless serial port).

Any help would be great!

You don’t need a level converter or talking to a bluesmirf, because it already uses logic voltage levels (0v / +5v). You only need it if you’re talking to a real serial port, which uses rs232 voltage levels (-9v / +9v or so).

I don’t know the answer to Dziubasek’s question though :frowning:

wiml: Have you by chance gotten the MSP430 to work correctly with the bluesmirf?

Dziubasek: Which TI code samples were you using?

Thanks again!

nope, I’ve used the msp430 and I’ve used the bluesmirf, but not together :slight_smile:
