-The EVAL-CN0391-ARDZ shield uses the [[http://www.analog.com/en/products/analog-to-digital-converters/precision-adc-10msps/ad7124-8| AD7124-8 part]] which is a **8-Channel** Low Noise, Low Power, **24-Bit**, Sigma-Delta **ADC** with PGA and Reference. All signal conditioning and excitation is performed by the AD7124-8, no additional components are needed.

 The **EVAL-CN0391-ARDZ** board has 4 thermocouple ports: **P1**~**P4**. The board has **4 Pt1000** RTDs: **R1**~**R4** close to each thermocouple socket for cold junction compensation. It supports all 8 types of thermocouple: **T, J, K, E, S, R, N, B** with full range temperature measurement. The RTD operates in the 2-wire mode and the excitation current is generated by the AD7124-8.

+The **CN0391_example** application reads the 4 RTD channels and the 4 thermocouple channels, processes them, makes all necessary calculations in order to output a linearized temperature for each available port. The **UART** interface (9600 baud rate, 1 start bit, 8-bits data length, no parity bits and 1 stop bits) is used to send data to a terminal window.

The **UART** interface (19200 baud rate, 1 start bit, 8-bits data length, no parity bits and 2 stop bits) is used to send data to a terminal window.
 The user has the possibility to enable/disable calibration on each channel separately. In the terminal window after initialization will appear information messages regarding this: if calibration is enable then the user will be informed when the calibration is completed, otherwise the user will be informed that the calibration is disabled (see //USE_RTD_CALIBRATION// and //USE_TH_CALIBRATION// parameters).

 ===== Configuring the Software Parameters =====
 Before running your program, make sure that you have configured the software appropriately to your settings:
-   * **RTD channel calibration** - //USE_RTD_CALIBRATION// parameter - enable/disable calibration on RTD channel - //YES// -> enable calibration; //NO// -> disable calibration(//CN0391.h//).
+   * **RTD channel calibration** - enable/disable calibration on RTD channel (//CN0391.h//).
-   * **Thermocouple channel calibration** - //USE_TH_CALIBRATION// parameter - enable/disable calibration on thermocouple channel - //YES// -> enable calibration; //NO// -> disable calibration(//CN0391.h//).
+<code>
-   * **Terminal refresh** - //DISPLAY_REFRESH// parameter - how often to refresh the output data - input time value in [msec] (//CN0391.h//).
+    #define USE_RTD_CALIBRATION  YES  // Set YES to enable calibration on RTD channel, otherwise set to NO
-   * **Thermocouple types** - //P1_TYPE// - //P4_TYPE// parameters - selects on of available thermocouple types for each port - //TYPE_T// - //TYPE_B// -> thermocouple types(//Thermocouple.h//).
+</code>
+   * **Thermocouple channel calibration** - enable/disable calibration on thermocouple channel (//CN0391.h//).
+<code>
+    #define USE_TH_CALIBRATION   YES   // Set YES to enable calibration on TC channel, otherwise set to NO
+</code>
+   * **Terminal refresh** - how often to refresh the output data - input time value in [msec] (//CN0391.h//).
+<code>
+    #define DISPLAY_REFRESH     (1000)   //ms
+</code>
+   * **Thermocouple types** - selects available thermocouple types for each port (//Thermocouple.h//).
+<code>
+    #define   P1_TYPE    TYPE_T      // TYPE_T,TYPE_J,TYPE_K,TYPE_E,TYPE_S,TYPE_R,TYPE_N,TYPE_B
+    #define   P2_TYPE    TYPE_T      // TYPE_T,TYPE_J,TYPE_K,TYPE_E,TYPE_S,TYPE_R,TYPE_N,TYPE_B

     Data: 8 bit
     Parity: none
-    Stop: 2 bit
+    Stop: 1 bit
