General issue report
Hello, I am trying to use 6 WS2812B strips but when trying to create "led_strip_new_rmt_device()" it causes en error. I know that in ESP32 C3 there are only 2 RMT TX channels. Is there any way to share RMT channels along strips ? The only solution i found is "led_strip_del()" before starting to animate other strip, but it doesn't satisfy my program needs.
E (309) rmt: rmt_tx_register_to_group(152): no free tx channels E (309) rmt: rmt_new_tx_channel(288): register channel failed E (319) led_strip_rmt: led_strip_new_rmt_device(154): create RMT TX channel failed
Hi @KacperStib Could you expand what issue you met when you call the delete function?

Hello @suda-morris, The solution with led_strip_del() is bad for me because, the strip loses it's former pixels colours. For steady backlight with same colour for all pixels in the strip this solution is OK. But I try to do some more advanced animation on this strip like rainbow chase. I simply animate in every step one pixel after antoher, so I need the memory, which is erased with calling "led_strip_del()" function.
Hi @KacperStib Thanks for the feedback. It sounds reasonable to me. We will provide a way to dynamically switch the GPIO used by RMT TX channel.
I've detached the leds from the api object and confirmed it works great. The array variable at the end of the struct needs to be converted to a pointer and everything just works.
