Ledstrip.h multi DMA

[kurtwerbrouck]

Is your feature request related to a problem?

hello

is it possible to use Ledstrip.h on 2 ledstrips with DMA? I only can have 1 DMA on 1 single ledstrip working.

@kurtwerbrouck Can you link to a simplified example / project so I can see the code you're using - and also provide any error / warning output that you're getting when you try it?

For the LED strip communications, are you using RMT peripheral or what is the peripheral you're connecting the LED strip to?

hello

thanks for the reply , see attachment.

I am using an ESP32-p4 nano from waveshare with ethernet connection do receive the DMX artnet.

The artnet dmx is send by Resolume to drive 2 x ws2812 ledpanels 8x8, and 1 x ws2812 ledpanel 32x8( working on it).

ledstrip1 is running with DMA, .flags = {.with_dma = true},

ledstrip2/3/4 can t run an DMA, .flags = {.with_dma = false},

Hope this helps to simulate the issue.
