ALTERA DE 2 BOARD

This project divided into two parts: hardware and software. Hardware part includes the ALTERA board and three sensors, which converts physical quantities such as temperature, humidity, and rainfall into electrical analogue signal. An Analogue-to-Digital Converters (ADC) circuit is needed in order to convert the physical signal to an electrical signal. After signal conditioning the analog signals are given as input to the eight channels ADC to convert them into digital data. Altera periodically read these data from ADC and display the values of measured quantities on LCD display.
To know ALTERA

For software part, Field-Programmable Gate Array (FPGA) was found to be other alternative integrated circuit apart from microcontroller. Verilog HDL coding is applied to control all the system by reading the output signal from sensor and convert it to get the output (display).

The very basic nature of FPGAs allows it to be more flexible than most microcontrollers. The term field programmable already tells you that the whole FPGA device can be reprogrammed to do any logic task that can be fitted into the number of gates that it has. You can rewire all the logic gates to configure it to the task you had in mind. Microcontrollers already have their own circuitry and instruction set that the programmer must follow in order to write code for that microcontroller which restricts it to certain tasks.
