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.

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.

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.

Re: Excel VBA for IOWarrior and Sensirion SHT7x
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.

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.

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.

Re: LED-Warrior14-S signals 3.3V level compatability.
No
The chip needs 5 V supply, the I2C signals are 3.3 V compatible.

Re: JoyWarrior56FR1 Kommunikation unter Raspberry OS mit pyUSB
Der JW56FR1 gibt von sich aus die Daten über die Joystickschnittstelle aus, mit den abgespeicherten Parametern. Dafür muss nichts konfiguriert werden.
