Serial Grapher Application
In order to unsecure a device with this application, please specify the
hardware interface that you are using. If your P&E Multilink or Cyclone PRO is
successfully detected, the name of a corresponding device will appear in the
Port text box. Please select HCS08 or CFV1 from the Select Architecture drop
down menu and press the Perform Unsecure button. The application will
finish unsecuring and erasing the device shortly thereafter.
This PC-based application is included on the DVD-ROM that accompanies
the DEMOEM, and may also be found at:
http://www.pemicro.com/fixedlinks/demotoolkit.cfm.
This PC-based application is a generalized version that may be used with
custom microcontroller code which transmits data in the correct format. The
serial graphing utility allows incoming data on the PC serial port (or one of
P&E’s virtual serial ports) to be automatically graphed in time or displayed as
a series of bar graphs. The virtual serial port exists on several of P&E’s
Embedded Multilink designs including the DEMOEM board.
To start using this application, please choose COM or virtual USB COM
settings from the drop-down Port menu. By doing so, you are specifying the
port on the evaluation board that will be used for transmitting captured
accelerometer data via a COM or USB serial port. Please make sure that
jumpers J7 and J8 are set accordingly. Prior to starting serial data capture,
please specify the Baud setting to reflect the parameter at which your serial
communication interface is operating. Once your port settings are configured,
please plug a USB or DB9 serial cable into the evaluation board and click on
the Open Serial Port and Start Demo buttons. The graphing of data can be
