ds18b20 spartan 3e

Hi, i need to connect a temperature sensor and a pressure sensor to a spartan 3 fpga board.

Can anyone suggest some senors that can be inferfaced to this?

Im not sure on what the spec of the sensors should be for this application.....
 

sensor interfacing

DS18S20 with 1-wire connection to FPGA
PT100 to analog input of FPGA

spartan 3 spi ip

thanks, anymore suggestions, for pressure sensors also?

Temperature Sensor to FPGA.

To interface these temp sensors to FPGA's you will have to use SPI-based temperature sensors that give you digital output. You can then connect these outputs to the FPGA by using a SPI IP in the FPGA.

Pressure sensors

Most pressure sensors output an analog signal. For such devices you will have to interface the pressure sensor to an ADC first and then take in the digital signals from the ADC to the FPGA.

AFAIK, Spartan 3 doesn't have analog inputs. I'd be realy surprised if it has one.

The spartan3E starter board has an ADC/DAC on board.... so you can communicate with it just like I did over SPI interface....

Oh, im not exactly sure if i will be using the spatarn 3 or the 3E yet
