| The **ADuCM360_demo_cn0398** project uses the [[http://www.analog.com/en/design-center/reference-designs/hardware-reference-design/circuits-from-the-lab/cn0398.html|EVAL-CN0398-ARDZ]] shield which is a single supply, low power, high precision complete solution for soil moisture and pH measurements, including temperature compensation. The circuit is optimized for capacitive soil moisture sensors that are insensitive to water salinity and do not corrode over time. The circuit also measures soil pH so it increases the range of applications where this shield can be used. | The **ADuCM360_demo_cn0398** project uses the [[adi>en/design-center/reference-designs/hardware-reference-design/circuits-from-the-lab/cn0398.html|EVAL-CN0398-ARDZ]] shield which is a single supply, low power, high precision complete solution for soil moisture and pH measurements, including temperature compensation.

| The circuit is divided into three independent measurement front ends: pH, soil moisture, and temperature. After signal conditioning, the three channels share an [[http://www.analog.com/en/products/analog-to-digital-converters/precision-adc-20msps/ad7124-8.html|AD7124-8]], 24-bit sigma-delta (Σ-Δ) ADC. The **AD7124-8**, is a low power, low noise, completely integrated analog front end for high precision measurement applications. | The circuit is divided into three independent measurement front ends: pH, soil moisture, and temperature.

| The board offers the possibility to configure **Vin** supply voltage (**P10** connector) in order to use **5V** or **7V-12V**.

For temperature compensation can be used an RTD //PT100// sensor, 2-wire (this is used in the demo), 3-wire or 4-wire connection (see **P1** connector). For this demo was used for the moisture measurement the //VH400// sensor (**P2**) and for pH measurement //Atlas Scientific// sensor (**J1**). The **ADuCM360_demo_cn0398** application processes ADC outputs for all 3 channels (RTD, pH and moisture), calculates pH and moisture values using as input RTD temperature value. This data is sent to cloud using the **UART** module on the base board and the **ESP8266 WiFi module**.

| ===== Obtaining the Source Code ===== | ===== Obtaining the Software ===== |
| |
| We recommend not opening the project directly, but rather import it into CrossCore Embedded Studios and make a local copy in your workspace. | There are two basic ways to program the ADICUP3029 with the software for the CN0398. |
| | - Dragging and Dropping the .Hex to the Daplink drive |
| | - Building, Compiling, and Debugging using CCES |
| |
| The source code and include files of the **ADuCM360_demo_cn0398** can be found on Github: | Using the drag and drop method, the software is going to be a version that Analog Devices creates for testing and evaluation purposes. This is the EASIEST way to get started with the reference design |
| |
| <WRAP round 80% download> | Importing the project into CrossCore is going to allow you to change parameters and customize the software to fit your needs, but will be a bit more advanced and will require you to download the CrossCore toolchain. |
