WS2812B Emteria with Raspberry PI 4 How-to?
I need to manage the WS2812B address tape with Raspberry PI 4.
When controlled via
There is not enough frequency. The minimum pulse duration is 50 milliseconds, to supply control to the address tape, a duration of 350 nanoseconds and 900 nanoseconds is needed, respectively, for 0 and 1.
These commands show that the PWM is not enabled:
To do this, pin 13 is used as a PWM, described in the device tree.
Tell me how to enable PWM for 13 pins in Emerita, Advanced license?
