3.2.4.1 Downloading and Uploading Calibration Constants
The Tera Term utility called for in these sample programs can be downloaded from
hp.vector.co.jp/authors/VA002416/teraterm.html.
These sample programs must be compiled to run from the fast SRAM. To do so, select
Options > Project Options
“
Before you compile and run these sample programs, you
will also need to connect the RS-232 header at J4 to your
PC as shown in the diagram using the serial to DB9 cable
supplied in the Development Kit.

THERMISTOR.C
for display to the Dynamic C
thermistor is the one included in the Development Kit whose values for beta, series
resistance, and resistance at standard temperature are given in the part specification.
Install the thermistor at location JP25 on the Prototyping Board before running this
sample program. Observe the temperature changes shown in the Dynamic C
window as you apply heat or cold air to the thermistor.

block using a terminal emulation utility such as Tera
Term.
Start Tera Term or another terminal emulation program
on your PC, and configure the serial parameters as
follows.
Now compile and run this sample program. Verify that the message “Waiting, Please
Send Data file” message is being displayed in the Tera Term display window before
proceeding.
Within Tera Term, select
OPEN
Term will indicate whether the calibration data were written successfully.
