+# AD7606X-FMC/ZED HDL Project
+
+The parameters configurable through the `make` command, can be found below, as well as in the **system_project.tcl** file; it contains the default
+configuration.
+
+If other configurations are desired, then the parameters from the HDL project (see below) need to be changed, as well as the Linux/no-OS project configurations.
+
+All of the configuration modes can be found in the chosen chips's data sheet. We offer support for only a few of them.
+
+- INTF - Defines the operation interface
+  - 0 - Parallel
+  - 1 - Serial
+- NUM_OF_SDI - Defines the number of SDI lines used: 1, 2, 4 or 8
+- ADC_N_BITS - Specifies the ADC resolution: 16 or 18 bits (only for the Parallel Interface)
+
+For the serial interface (INTF=1), the following parameters will be used in make command:
+- INTF
+- NUM_OF_SDI.
+
+For the parallel interface (INTF=0), the following parameters will be used in make command:
+- INTF
+- ADC_N_BITS.
+
+:warning: When switching between Serial and Parallel Interface,
+make sure to replicate this move in hardware too by changing the hardware switch (JP5). Rebuild the design if the variable has been changed.
+
+### Example configurations
+
+This specific command is equivalent to running `make` only:
+
+#### 16-bit parallel interface (default)
+
+```
+make INTF=0 ADC_N_BITS=16
+```
+
+#### 18-bit parallel interface
+
+```
+make INTF=0 ADC_N_BITS=18
+```
+
+#### Serial interface with 1 SDI line
+
+```
+make INTF=1 NUM_OF_SDI=1
+```
+
+#### Serial interface with 2 SDI lines
+
+```
+make INTF=1 NUM_OF_SDI=2
+```
+
+#### Serial interface with 4 SDI lines
+
+```
+make INTF=1 NUM_OF_SDI=4
+```
+
+#### Serial interface with 8 SDI lines
+
+```
+make INTF=1 NUM_OF_SDI=8
+```
