AN-1050: EnerChip™ EH with TI LaunchPad
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.
