Terminal Emulator Quirks

In Windows the terminal emulator must be operating on a USB COM port emulation driver which instantiates as

COMX where X could be any number based on the particular port and particular connection of the LaunchPad

hardware when the LaunchPad is plugged into the USB port. Various terminal emulators can be quirky on

“hooking” or connecting to a particular COM port. Use the device manager to make sure the COM port for the

“MSP430 applications UART” appears under Ports (COM and LPT). If the “MSP430 applications UART” does not

appear try unplugging the LaunchPad/USB cable from your PC and plugging it into a different USB port. Once

you see the “MSP430 applications UART”, note the COM port number and configure the terminal emulator to use

that COM port. Remember that when you unplug the USB cable to the LaunchPad, the COM port will probably

disappear and so will its connection to the terminal emulator. You may need to close the terminal emulator,

unplug the LaunchPad cable, wait a few seconds, plug in the LaunchPad, restart the terminal emulator, and

configure the terminal emulator.

To configure the desired COM port, set the port for 8 bits, 9600 baud, no parity, with one stop bit and no flow

control.

Code Description

The datalogger code is based on the original LaunchPad temperature demo code. This original code makes use

of many timer modes and uses the watchdog timer as a switch debounce timer. The timer code and the function

PreApplicationMode was modified to make the button detect a short or long button press. There are several

routines that reconfigure the timers for the various modes of the LaunchPad demo and an additional mode was

added for the Cymbet Datalogger demo. The Cymbet Datalogger demo code checks for the modem cable not

present and then calls the CymbetLogData routine which reconfigures the timers, runs the Cymbet datalogger,

and then blinks the red LED when full. If the modem cable is present the routine waits for a button press to dump

any logged data, erases the logged data if the button press was long, and then returns to the original LaunchPad

demo.
