+
+### Software Support
+
+We provide a library for the DALI_2 Click on our [LibStock](https://libstock.mikroe.com/projects/view/2333/dali-2-click) 
+page, as well as a demo application (example), developed using MikroElektronika 
+[compilers](http:https://shop.mikroe.com/compilers). The demo can run on all the main 
+MikroElektronika [development boards](http:https://shop.mikroe.com/development-boards).
+
+**Library Description**
+
+Library implements DALI master functionalities. 
+
+Key functions :
+
+- ``` void dali2_sendCmd(const uint8_t balAddress, const uint8_t cmd, const uint8_t cmdType, const uint8_t folType) ``` - Executes DALI command
+- ``` void dali2_masterInit() ``` - Initializes master functionality
+- ``` uint8_t dali2_masterStatus() ``` - Returns master status
+
+**Examples Description**
+
+The application is composed of three sections :
+
+- System Initialization - Initializes GPIO pins for TX and RX
+- Application Initialization - Initializes driver, initializes DALI master functionality and configures timer
+- Application Task - (code snippet) - Application task is composed of three sequences, first sequence toggling
+light twice with delay of one second. Second sequence decreases intensity of light by 8 steps with delay of 
+half second. Third sequence increases intensity of light by 8 steps with delay of half second.
+
+
+```.c
+void applicationTask()
+{
+ uint8_t counter;
+
+ for (counter = 0; counter < 2; counter++)
+ {
+ dali2_sendCmd(_DALI2_ADDRESS01, _DALI2_OFF, _DALI2_BROADCAST_CMD, _DALI2_FOLLOWING_COMMAND);
+ Delay_ms( 1000 );
+ dali2_sendCmd(_DALI2_ADDRESS01, _DALI2_RECALL_MAX_LEVEL, _DALI2_BROADCAST_CMD, _DALI2_FOLLOWING_COMMAND);
+ Delay_ms( 1000 );
+ }
+
+ for (counter = 0; counter < 8; counter++)
+ {
+ dali2_sendCmd(_DALI2_ADDRESS01, _DALI2_DOWN, _DALI2_BROADCAST_CMD, _DALI2_FOLLOWING_COMMAND);
+ Delay_ms( 500 );
+ }
+
+ for (counter = 0; counter < 8; counter++)
+ {
+ dali2_sendCmd(_DALI2_ADDRESS01, _DALI2_UP, _DALI2_BROADCAST_CMD, _DALI2_FOLLOWING_COMMAND);
+ Delay_ms( 500 );
+ }
+
+ current_state = dali2_masterStatus();
+}
+```
+
+**Note** 
+
+This implementation of DALI master requires timer with exact 104 uS interrupt time. The MCU used 
+for example must be cappable to execute ```void dali2_isr()``` function in time less than 104 uS.
+In theory it is usable on faster MCUs but before usage you should check does your MCU is cappable to 
+acomplish dali2_isr function call for less than 104us.
+
+
+The full application code, and ready to use projects can be found on our 
+[LibStock](https://libstock.mikroe.com/projects/view/2333/dali-2-click) page.
