Library Description

The 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 demo 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, the first sequence toggles light twice with a delay of one second. The second sequence decreases intensity of light by 8 steps with a delay of half a second. The third sequence increases light intensity by 8 steps with a delay of half a second.

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 capable 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 if your MCU is capable to execute dali2_isr function call for less than 104us.
