I searched the msp forum here, but couldn't find any specific description of the problem i realize this proves nothing , so i'm posting as complete a description of it. If you do need a device with a flawless uart, i recommend using one of the newer value line chips that have a hardware uart built in. If you have any queries, doubts or feedback on this tutorial please share in our discussion forum. It is recommended to change this to the microcontroller you are using. The msp430 launchpad board comes with an integrated usb-to-uart adapter that supports baud rates up to 9600. Here is the example i2c interrupt routine.
Since i prefer code composer studio ccs over the other methods for programming the msp430, i will quickly discuss how to use someone else's code in your projects. Msp430g2xxxx series for eg msp430g2553 comes with a 10 bit successive approximation adc that can operate at 200ksps. In section 7, you'll see how to use software to create a uart on a device that may lack that peripheral. You can see those labeled on the silk screen on the msp430 from gp i/o to the timer a0 function. Again, the ez430 is not compatible with linux, so it will not work with your current setup. Asus en6200tc512. Msp430 launchpad uart driver - to set the baud rate, we will use the table from the reference manual.
