Interface ad7705 with arduino due

Reference no: EM131910120

To interface AD7705 With Arduino Due.

1. The input is coming from AD8495,Which is connected to pin number 6(Positive) And Pin 11(Grounded)(Negative) of AD7705

2. K-Type Thermocouple is given as input to AD8495

3. In between PIN 1,4,14 and 13 i.e SCLK,CS,DIN,DOUT optocouplers(EL817C) are connected in order to reduce 5v to 3.3v for Arduino Due

4. PIN 9th i.e reference in (Plus) REF192 is connected

5. Reset PIN 5th is connected to 5V.

6. Master clock signal i.e MCLKIN (PIN 2) is getting from arduino Due and a program is written to generate 2MHz

7. Arduino Due SPI is being used to interface Arduino Due tft Display Screen.

Requirements for our code :

To interface AD7705 With Arduino Due.

We need 10 measuring points per second and the output voltage should be converted to temperature.

Attached a rar file of the code, but i am getting an Output with the due tool, which i need to resolve

using Arduino IDE 1.7.10.

Attachment:- temp value arduino.rar
