Digital Thermometer

EDA platform : ispADVANCED

design type : ABEL

 

Description

*The Digital Thermometer contains the necessary logic to allow the displaying of temperature (in real-time onto a 7 segment display) from a off-shelf digital thermal sensors.

*Contains an IIC serial port to interface to IIC digital thermal sensor

*Contains multiplexed 3-digit 7-segment LED driver

*Contains 8 bit HEX to 3 digit (4bits) BCD converter. This converter is composed of a multiplier (sequential) and a succesive approximation integer divider.

*The temperature can be displayed as Celcius or Fahrenheit.
