4.14 I2C EEPROM test
4.15 I2C Temperature Sensor test
Reference manual: EM-LPC13xx Reference Manual.pdf
Source code location: 03-Software\Examples\14-I2C_EEPROM
Test description: This testcase configures I2C working in master mode, and Read/Write EEPROM
using I2C bus. Init buffer,send the buffer data to EEPROM,read them and compare. If the data read is
the same as data written,then test success.
Test phenomenon: Build the program and download it inside the evaluation board. Open PC
HyperTerminal and push RESET button. If it displays message “I2C EEPROM test success!” in
the terminal,then test success. Phenomenon is as follows.

Test description: This example describes how to configure I2C work in master mode. It test the
temperature sensor LM75 and read the four registers' value. They are Temperature
Register,Configuration Register,Tos Set Point Register and Thyst Set Point Register.
Test phenomenon: Build the program and download it inside the evaluation board. Open PC
HyperTerminal and push RESET button. If test success,it may display the four registers’ value in the
terminal. Phenomenon is as follows.
