The IO-Warriors take care for that. If you do a write commend without generating a stop then do a read commend it will automatically generate a restart condition.

Re: Neues Produkt über Kickstarter: I2C zu PWM Controller

In GitHub haben wir jetzt ein Beispiel, wie man LED-Warrior18 von einem ESP8266 Modul aus ansteuert.

Re: New product on Kickstarter: I2C to PWM controller

We have just added an example how to use LED-Warrior18 with ESP modules, in this case with a ESP8266.

Re: LW-13 configuration

There is no DALI command for smooth fading. This is a parameter that you have to set inside the DALI device. FadeRate and FadeTime are the values that set the speed at which your lamp transitions from one power setting to another. If I remember it correct FadeTime is the time for transition from one...

Neues Produkt über Kickstarter: I2C zu PWM Controller

LEDs dimmen mit Singleboard-Computern ist oft nicht so einfach. Die Auflösung der PWM reicht nicht, die Programmierung ist umständlich, oder es ist gar keine PWM in Hardware vorhanden. In jedem Fall fehlt der Leistungstransistor, um die LEDs ansteuern zu können. Wir haben uns entschieden dagegen etw...

New product on Kickstarter: I2C to PWM controller

Dimming LEDs with a single board computer is not always easy. The resolution of the PWM is sometimes insufficient, programming ist badly supported, or the PWM hardware is missing completely. In any case a power stage is missing to drive the LEDs. So we decided to do something about this and started ...

Re: LW-12, LW-14 Questions

DALI does not have any option to poll all devices at once, at least not one that will give you a useful result. So there is no way but to query each device separately. Reading the Command register in the LW14 makes only sense when that status flags indicate that new data has been received. Not sure ...

Please keep in mind that this works only with IOW24. IOW24 is a discontinued product. It did run out in 2018.

Re: IO-Warrior 28 replacing IO Warrior 24

IO-Warrior28 uses full speed USB, versus the low speed on IOW24. This allows 1000 reports per second and the data payload is 64 bytes versus the 8 on the IOW24. Also it has a dedicated interface for I2C which means the bandwidth is not shared with other functions. IOW28 can saturate a 400 kHz I2C an...

Re: LED-Warrior14 DALI initialisation

The LW14 is fine with a 3.3 V I2C and since it is the device and not the master this should work without a level shifter. A LW14-02MOD should only be used when the complete circuit is powered off the DALI bus via the LW14-02MOD. The DALI deployment is a somewhat complex process. We don't have comple...

Re: Scheme for two LED-Warrior12

Yes this does work, you don't even need to double the R4 and R6.

Driving the relays should work if you are going only to zero or full output. The relay will have no chance to follow the 730 Hz PWM.
