+### Software Support
+
+We provide a library for the Multimeter Click on our [LibStock](https://libstock.mikroe.com/projects/view/2243/multimeter-click) 
+page, as well as a demo application (example), developed using MikroElektronika 
+[compilers](http://shop.mikroe.com/compilers). The demo can run on all the main 
+MikroElektronika [development boards](http://shop.mikroe.com/development-boards).
+
+**Library Description**
+
+Library contains calibration function, to be used on startup for more accurate readings, as well as
+4 functions that measure Voltage, Current, Resistance and Capacitance.Calibration should be performed at startup 
+when all measurement leads are disconnected.
+
+Key functions :
+
+- ``` float multimeter_measureU() ``` - This function measures voltage, and returns the value in millivolts.
+- ``` float multimeter_measureR() ``` - This function measures resistance, and returns the value in ohms.
+- ``` float multimeter_measureC() ``` - This function measures capacitance, and returns the value in nanofarads.
+- ``` float multimeter_measureI() ``` - This function measures current, and returns the value in milliamperes.
+
+**Examples Description**
+
+The application is composed of three sections :
+
+- System Initialization - Initializes pin control, spi peripheral and logger.
+- Application Initialization - Initializes the driver, and performs calibration.
+- Application Task (Code snippet) - Outputs read values.
+
+
+```.c
+
+    char text[20];
+    float value = 0;
+    value = multim_measureR();
+    FloatToStr(value,text);
+    mikrobus_logWrite("R = ",_LOG_TEXT);
+    mikrobus_logWrite(text,_LOG_TEXT);
+    mikrobus_logWrite("  Ohms",_LOG_LINE);
+
+    value = multim_measureU();
+    FloatToStr(value,text);
+    mikrobus_logWrite("U = ",_LOG_TEXT);
+    mikrobus_logWrite(text,_LOG_TEXT);
+    mikrobus_logWrite("  mV",_LOG_LINE);
+
+
+    value = multim_measureI();
+    FloatToStr(value,text);
+    mikrobus_logWrite("I = ",_LOG_TEXT);
+    mikrobus_logWrite(text,_LOG_TEXT);
+    mikrobus_logWrite("  mA",_LOG_LINE);
+
+
+    value = multim_measureC();
+    FloatToStr(value,text);
+    mikrobus_logWrite("C = ",_LOG_TEXT);
+    mikrobus_logWrite(text,_LOG_TEXT);
+    mikrobus_logWrite("  nF",_LOG_LINE);
+
+    mikrobus_logWrite("-------------------",_LOG_LINE);
+    Delay_ms( 1000 );
+
+```
+
+The full application code, and ready to use projects can be found on our 
+[LibStock](https://libstock.mikroe.com/projects/view/2243/multimeter-click) page.
+
+Other mikroE Libraries used in the example:
+
+- Conversions
+- C_String 
+- UART
+
+**Additional notes and informations**
+
+Depending on the development board you are using, you may need 
+[USB UART click](http://shop.mikroe.com/usb-uart-click), 
+[USB UART 2 Click](http://shop.mikroe.com/usb-uart-2-click) or 
+[RS232 Click](http://shop.mikroe.com/rs232-click) to connect to your PC, for 
+development systems with no UART to USB interface available on the board. The 
+terminal available in all Mikroelektronika 
+[compilers](http://shop.mikroe.com/compilers), or any other terminal application 
+of your choice, can be used to read the message.
