The MCP9800 Temperature Data Logger Demo Board 2, once programmed, will log 
temperature measurements for a predetermined amount of time until the 24LC16B is 
fully programmed with temperature data (i.e., 2,048 temperature readings). Each sam-
ple uses one byte of memory. The intervals can be changed in the firmware we have 
provided by changing the 

 variable. The firmware will take measurements 

for approximately 45 minutes (approx. 1 sample/sec).

The MCP9800 Temperature Data Logger Demo Board 2 has the following features:

• Small PCB layout. Can be placed virtually anywhere you need to measure 

temperature.

• Standard ICSP™ pinout so the firmware can be modified using a PICkit™ 2 pro-

grammer or any of Microchip’s programming tools using the ICSP programming 
adapter. 

• Standard Two-Wire 8-pin pinout (inverted) for easy reading of the 24LC16B into 

the SEEVAL

® 

32 evaluation tool software.

This section describes how to get your MCP9800 Temperature Data Logger Demo 
Board 2 programmed and ready to take temperature readings. The boards have been 
pre-programmed at the factory with the default settings, so it is not necessary to 
program them unless the firmware has been modified. It will also show how to read the 
logged data from the board into the SEEVAL

® 

32 evaluation tool software. Then it will 

show how to export that data from the SEEVAL 32 evaluation tool software and also 
how to import and display the data on an Excel spreadsheet.
