Version 1.11
2023-03-24

New Feature:

  • Define DEBUG_LOG was introduced in order to be able to switch logging on and off separately from the DEBUG version

  • Configuration parameter deactivateAutomaticSavePersistent has been introduced. If this is set, saving the persistent variables is only triggered by an internal action.

  • If the stack has reset the persistent variables to default values, the application is now notified by a reaction.

  • New reaction added to enable a distinction between Init and Reset when resetting the persistent variables to default values

  • OperatingMode 0x80 - 0xFF is now permitted by the stack

  • The calculation of the target level has been revised. When the value is changed, the application is notified via a newly introduced reaction

  • New configuration parameters have been introduced:
    - to specify the offset between the start of the stack and the current time
    - to use a random value for calculating the random seed

  • Repeated dimming now uses the actual (high resolution) light level as the start level instead of using the rounded ActualLevel.

  • The internal actions "DALILIB_ACT_INTERNAL_CTRL_GEAR_EXEC_DAPC" and "DALILIB_ACT_INTERNAL_CTRL_GEAR_EXEC_DAPC_RAW_VALUE" trigger a process that corresponds to that of an external incoming DAPC command and uses the existing settings (fading) during the transition.

  • Any number of custom Membanks can be created. The number of Membanks is still limited by MAXMEMBANKS

  • MAXMEMBANKS has been moved from "defines.h" to "libdali.h" and thus to the user-configurable area

  • For custom memory banks, addresses 1 and 2 can now be written to via `WRITE MEMORY LOCATION`.

  • In the gear_calc_actual_level() function, the calculation of the stepValues has been revised in order to increase the resolution when dimming.

  • New enumeration added that allows the application to differentiate between total and partial lamp failure when setting and querying the lamp failure status.

  • Make memory bank 1 available as a user memory bank in GEARS if DALI Part 251 DiiA extension is deactivated

  • Proprietary frames between 9 and 12 bits are now also reported to the application. These can also occur with responses from poorly programmed gears that should actually generate a collision. This allows the application to help itself.

  • SET OPERATING MODE now triggers a DALILIB_CTRL_GEAR_REACTION with the reaction code DALILIB_REACT_INTERNAL_CTRL_GEAR_SET_OPERATING_MODE

  • Function for deleting (reference) manufacturer-specific memory banks implemented

  • SET OPERATING MODE now triggers a DALILIB_CTRL_DEVICE_REACTION with the reaction code DALILIB_REACT_INTERNAL_CTRL_DEVICE_SET_OPERATING_MODE

Fix:

  • The reaction DALILIB_REACT_INTERNAL_CTRL_GEAR_DEFAULT_PERS_MEMORY now contains data in the struct gearReact

  • The IDENTIFY DEFICE command is executed according to specification, DALI_CTRL_DEVICE_IDENTIFY_DEVICE_TIME_MAX has been increased to 10s. The stack informs the application about a newly introduced reaction when the Identify device status changes.

  • The Identify device is reset for commands (except queries)

  • Send-Twice commands preceded by the ENABLE DEVICE TYPE command are executed.

  • The QUERY MANUFACTURER SPECIFIC MODE command is answered with Yes if the stack is running in a manufacturer-specific mode.

  • When the dimming curve is changed, the corresponding bit in the operatingMode variable is set or deleted.

  • When dimming using the dimming rate, overflow or underflow is avoided.

  • The stack configured as gear responds to the QUERY GEAR PRESENT command with Yes if the short address is MASK.

  • When dimming, the targetLevel is set directly to 0.

  • The Send Twice timeout has been reduced to 99 ms.

  • An underflow occurred in gear_calc_actual_level() during the calculation of stepValue; the calculation is now performed as a 64-bit integer.

  • Dimming processes are completed after the dimming time has elapsed

  • If targetLevel is 0, the actualLevel is set to 0 at the end of the dimming process

  • If the stepTime is low, the dimming process is only ended after the dimming step has been executed

  • After a system failure, the actualLevel is retained

  • When the first UP/DOWN command is executed, the first step is executed before the dimming process begins

  • When calculating the diffLevel in gear_calc_dimmrate(), the carryover is taken into account for UP/DOWN sequences

  • When UP and DOWN commands are received, the stack aborts the current dimming process

  • When calculating the stepTime of a dimming organ, a division by zero could occur; this is now tested and the division is avoided.

  • The DAPC(MASK) command retains limitError

  • With the UP command, the stack sets limitError if acutalLevel is already at maxLevel or minLevel or if the limits are exceeded when calculating the targetLevel

  • With a PowerOn, the stack sets the targetLevel with a check of the limits, so that limitError is also set if necessary

  • With DAPC sequences, the dimming process was calculated incorrectly so that there was no level change during dimming; now the dimming process is calculated correctly.

  • When executing the GO TO SCENE command (actualLevel equals targetLevel), no dimming process is triggered in this case

  • The stack only changes the actualLevel when the RECALL MIN LEVEL and RECALL MAX LEVEL commands are executed.

  • During the Identify device process, the stack set the actual light level to different brightnesses depending on the initializationState; now the stack always switches between off and 100 %.

  • When the Identify device process is ended, the actual light level is set when the process is ended

  • When executing the commands DAPC, SET POWER ON LEVEL and DTR0 (and other instructions), the stack terminates the Identify device process

  • The RECALL MIN LEVEL and RECALL MAX LEVEL commands set the actual light level to PHM or 100 %, regardless of the initializationState, if initializationState is not equal to DISABLED

  • During a dimming process, the new actualLevel is only set if the targetLevel has not yet been reached

  • In gear_init_after_power_cycle(), the targetLevel is only set together with the actualLevel after the power-on time has expired

  • The stack can differentiate between total lamp failure and partial lamp failure and communicate the respective status to it - the stack then sets the variables lampFailure and lampOn accordingly

  • The dimming times of fastFadeTime were taken from Table 1 in IEC 62386-207:2009, now the stack can use the dimming times from Table 1 in IEC 62386-207:2018, switchable to compile time via newly introduced define.

  • If the startTimeOffset was greater than the currentTime, the start time for the power-on procedure for gears and for the power cycle notification for application controllers was calculated incorrectly; now the start time is calculated correctly with wrap-around.

  • If a system failure occurs during the power-on time, the stack aborts the power-on procedure

  • IAR compiler warnings have been corrected

  • If minLevel and targetLevel were set to 1, the stack set the targetLevel to 0 when the STEP DOWN command was executed; now the targetLevel remains at 1 in this case.

  • When executing the GO TO SCENE (MASK) command, the stack sets powerCycleSeen to FALSE if sceneLevel is equal to MASK

  • If the DAPC (MASK) command is processed during the power-on procedure, the stack aborts this process.

  • The first dimming step of a dimming process was carried out 10ms after the start, even if the stepTime was significantly smaller; now a status frame is requested by the low-level driver in 2ms at the start of the dimming process, so that the first dimming step is carried out after 2ms if the stepTime is low.

  • With high-resolution dimming, the newly calculated light level was passed on to the application each time the timingHelper was called; now the stack only passes on the newly calculated light level to the application if the light level has changed.

  • Internal actions are executed during bus power down or system failure.

  • When initializing a stack instance, active instances are taken into account and the corresponding values in their memory bank 0 are updated

  • Keil compiler warnings have been corrected

  • If MEM_BANK1_EXTENSION is activated, 0x08 (V2.0) is reported for DT50 for QUERY_EXTENDED_VERSION_NUMBER

  • Defaults for MEM_BANK1 corrected

  • A go to scene message triggers the new internal reaction "DALILIB_REACT_INTERNAL_CTRL_GEAR_GO_TO_SCENE".

  • The scene index is written in reactValue.

  • Get scene internal action returns a percentage value. The raw value is still available via gearReact.reactRawValue.

  • All events now always contain the event dates

  • The reaction code of light sensors is no longer set to Unknown if the first bit of the input value is set.

  • The event filter for light sensors affects the report timer events and not just events that are triggered by value changes.

  • "QUERY LIGHT SOURCE TYPE" from Part102 - 11.5.19 corrected. Previously, the device type was output instead of the light source type.

  • The ProbitLab test 102.6.4 (fade to zero) could fail due to the internal time measurement for the API. (fixed)

  • LL-Driver gets version 1.12

 

Version 1.10
2022-05-31

New Feature:

  • Define DEBUG_LOG was introduced in order to be able to switch logging on and off separately from the DEBUG version

  • Configuration parameter deactivateAutomaticSavePersistent has been introduced. If set, saving the persistent variables is only triggered by an internal action.

  • If the stack has reset the persistent variables to default values, the application is now notified by a reaction.

  • New reaction added to enable a distinction between Init and Reset when resetting the persistent variables to default values

  • OperatingMode 0x80 - 0xFF is now permitted by the stack

  • The calculation of the target level in the stack has been revised. When the value is changed, the application is notified via a newly introduced reaction

  • New configuration parameter to specify the offset between the start of the stack and the current time.

  • Repeated dimming now uses the actual (high resolution) light level as the start level instead of using the rounded ActualLevel.

  • configuration parameter was introduced in order to be able to use a real random value for the calculation of the random seed.

  • In the gear_calc_actual_level() function, the calculation of the stepValues has been revised in order to increase the resolution when dimming.

  • Enumeration added, which allows the application to differentiate between total and partial lamp failure when setting and querying the lamp failure status.

Fix:

  • The reaction DALILIB_REACT_INTERNAL_CTRL_GEAR_DEFAULT_PERS_MEMORY was incorrect and now contains the expected data in the struct gearReact

  • The IDENTIFY DEFICE command is now executed according to specification, DALI_CTRL_DEVICE_IDENTIFY_DEVICE_TIME_MAX has been increased to 10s. The stack informs the application about a newly introduced reaction when the Identify device status changes.

  • Identify device is now reset for commands (except queries)

  • Send-Twice commands with the preceding ENABLE DEVICE TYPE command have been discarded and are now executed.

  • The QUERY MANUFACTURER SPECIFIC MODE command was ignored and is now answered with Yes if the stack is running in a manufacturer-specific mode.

  • The LED command QUERY OPERATING MODE was answered incorrectly - the active dimming curve was ignored; now the corresponding bit in the operatingMode variable is set or deleted when the dimming curve is changed.

  • When dimming using the dimming rate, an arithmetic overflow or underflow could occur; this is now tested and the overflow or underflow is avoided.

  • The stack configured as gear did not respond to the QUERY GEAR PRESENT command if the short address was MASK. Now the request is always answered with yes.

  • When dimming to level 0, the targetLevel was first set to minLevel and only after dimming to 0. Now the targetLevel is set directly to 0.

  • The Send Twice timeout has been set to 99 ms.

  • An underflow occurred in gear_calc_actual_level() during the calculation of stepValue; the calculation is now performed as a 64-bit integer.

  • Dimming processes sometimes ended too early, now the dimming process is completed exactly after the dimming time has elapsed.

  • With targetLevel equal to 0, the actualLevel was already set to 0 during the dimming process; now the actualLevel is only set to 0 at the end of the dimming process.

  • With a low stepTime, it could happen that the dimming process was ended before the last dimming step was executed; now the dimming process is only ended after the dimming step has been executed.

  • After a system failure, the actualLevel was set to zero, now the actualLevel is retained.

  • When the first UP/DOWN command was executed, the first step before the start of the dimming process was ignored; now this step is executed.

  • When calculating the diffLevel in gear_calc_dimmrate(), the carryover was ingorized so that too few dimming steps were performed for UP/DOWN sequences; now the carryover is taken into account for UP/DOWN sequences.

  • The current dimming process was not aborted when UP and DOWN commands were received; now the stack aborts the current dimming process.

  • When calculating the stepTime of a dimming organ, a division by zero could occur; this is now tested and the division is avoided.

  • With the DAPC(MASK) command, imitError was set to FALSE, now limitError is retained.

  • With the UP command, limitError was not set if maxLevel was exceeded during execution. Similarly, limitError was not set for the DOWN command if minLevel was undershot during execution. Now the stack sets limitError if acutalLevel is already at maxLevel or minLevel or if the limits are exceeded when calculating the targetLevel.

  • With a PowerOn the targetLevel was set directly without checking the limits, now the stack sets the targetLevel with checking the limits, so that limitError is also set if necessary.

  • With DAPC sequences, the dimming process was calculated incorrectly so that there was no level change during dimming; now the dimming process is calculated correctly.

  • When executing the GO TO SCENE command, a dimming process was triggered although actualLevel was equal to targetLevel, now no dimming process is triggered in this case.

  • During the Identify device process the actualLevel was changed, now the stack only changes the actualLevel when the RECALL MIN LEVEL and RECALL MAX LEVEL commands are executed.

  • During the Identify device process, the stack set the actual light level to different brightness levels depending on the initializationState, now the stack always switches between Off and 100%.

  • When the Identify device process was terminated, the actual light level was only set if the timer had expired; now it is always set when the process is terminated.

  • When executing the commands DAPC, SET POWER ON LEVEL and DTR0 (and further instructions) the stack did not finish the Identify device process, now the stack finishes the process.

  • The RECALL MIN LEVEL and RECALL MAX LEVEL commands always set the actual light level to the same level regardless of the initializationState; now the two commands set the actual light level to PHM or 100% if the initializationState is not equal to DISABLED.

  • During a dimming process in which the targetLevel had already been reached, the new actualLevel was not recalculated but was still set; now the new actualLevel is only set if the targetLevel has not yet been reached.

  • In gear_init_after_power_cycle() the targetLevel was already set depending on the powerOnLevel, now the targetLevel is only set together with the actualLevel after the power-on time has expired.

  • The stack did not differentiate between total lamp failure and partial lamp failure, now the application can communicate the respective status to the stack and the stack sets the variables lampFailure and lampOn accordingly.

  • The dimming times of fastFadeTime were taken from Table 1 in IEC 62386-207:2009, now the stack can use the dimming times from Table 1 in IEC 62386-207:2018, switchable to compile time via newly introduced define.

  • If the startTimeOffset was greater than the currentTime, the start time for the power-on procedure for gears and for the power cycle notification for application controllers was calculated incorrectly; now the start time is calculated correctly with wrap-around.

  • If a system failure occurred during the power-on time, the power-on procedure was not aborted, now the stack aborts the power-on procedure when a system failure is detected.

  • IAR compiler warnings have been corrected

  • If minLevel and targetLevel were set to 1, the stack set the targetLevel to 0 when the STEP DOWN command was executed; now the targetLevel remains at 1 in this case.

  • When executing the GO TO SCENE (MASK) command, powerCycleSeen was not reset, now the stack sets powerCycleSeen to FALSE even if sceneLevel is equal to MASK.

  • If the DAPC (MASK) command was processed during the power-on procedure, the power-on procedure continued to run unchanged; now the stack aborts the power-on procedure when processing the DAPC (MASK) command.

  • The first dimming step of a dimming process was carried out 10ms after the start, even if the stepTime was significantly smaller; now a status frame is requested by the low-level driver in 2ms at the start of the dimming process, so that the first dimming step is carried out after 2ms if the stepTime is low.

  • With high-resolution dimming, the newly calculated light level was passed on to the application each time the timingHelper was called; now the stack only passes on the newly calculated light level to the application if the light level has changed.

  • Internal actions were discarded during bus power down or system failure, now internal actions are also executed during bus power down or system failure.

  • If several instances of the stack were started on a bus unit, these were not taken into account during initialization; now, when a stack instance is initialized, instances that are already active are taken into account and the corresponding values in their memory bank 0 are updated.

  • Keil compiler warnings have been corrected
