This is an Energia sketch for the TI MSP430 LaunchPad with the MSP430G2553, which provides encoding and decoding of Morse code. Morse symbols received by the UART are encoded and "sent" on the LaunchPad's green LED; symbols keyed on pushbutton S2 are decoded and written to the microcontroller's UART.
This program relies on the MSP430G2553's hardware UART, and so requires the LaunchPad's jumpers to be configured accordingly.
