void E2_WriteMem(addr, data),

void E2_WriteBurst(addr, times, *buf)

This set of functions:

●

Reads/writes to/from EEPROM data

3.2.6

lite_timer_8bit.c,

lite_timer_8bit.h

These files are the timing module. They contain all virtual timers which are 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.

The most important functions of these files are given below in bold.

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) which was started during power-on (using the

Timer_Lite_Init() function)
