Hardware configuration
Hardware configuration
This application has been developed and tested by interfacing the ST72325 daughter board
with the main REva motherboard. The LM135 temperature sensor, connects to channel 2 of
ADC and the temperature is stored in the on-board I²C EEPROM. Figure 4 shows the
hardware setup that you can use to develop this application if you are not using the REva
board.
