It appears that there is a bug with Energia, some driver, or my computer. When I try to send anything from the MSP430 to my laptop over the serial port, the data gets corrupted in a systematic way. All bits are duplicated in place and then a zero is appended to the end of the bits. For example, if I send across a 1 (0b1), it becomes 6 (0b110), and if I send across a 2 (0b10), it becomes 24 (0b11000).
Below, I have a basic Hello World example that captures the problem pretty clearly. Please let me know if you can replicate the problem and/or have a solution.
