u16 E2_ReadMem(u16 VirtAddress,uint16_t* Data)

•

Reads data from EEPROM

3.2.6

lite_timer_8bit.c

These files constitute the timing module. They contain all the virtual timers needed for DALI

timing, such as intervals for the dimming function and DALI timeouts. Reference timer ticks

come from the DALI I/O pin driver layer.

void Timer_Lite_Init(void)

This function:

•

Initializes the timing module

•

Initializes the internal variables to their default state

void RTC_LaunchTimer(timer_value)

This function:

•

Initializes a timeout for DALI command repetition

void RTC_LaunchUserTimer(TimerCount),

void RTC_DoneUserTimer(void)

This set of functions:

•

Dims the update intervals (start and stop)

void RTC_LaunchBigTimer(mins)

This function:

•

Initializes the timeout (usually 15 minutes) - expiration of the DALI "Initialize" command

void RTC_LaunchDAPCTimer(void)

This function:

•

Initializes the timeout (200 ms) - expiration of the DALI "DAPC sequence" command

void PowerOnTimerReset(void)

This function:

•

Stops the power-on timeout (600 ms) previously initialized during power-on (using the

Timer_Lite_Init() function)
