I am using fastLed on a ESP8266 12E. I have read that the new library Fastled can do parallel output to increase fps. Will it work on the esp or is it just for the teensy ?
Will multi controller setup with the esp will increase my FPS ?
Thank you

ESP8266 still makes SPI bit banging only, while a Teensy is capable of DMA. So, if you really want speed, go with a Teensy (which can do parallel output on top!)

I didn’t understand the difference with using multiple controllers but ESP seems supported.

@Thomas_Runge Indeed I have just made the test ‘splitting’ the screen towards several pins do not increase the fps even worse the fps slightly went down -3fps :). Thank you for the tip. I like the esp8266 as it has the wifi onboard.But as I have 600 leds the refresh of the screen takes 18ms (55fps). Any other calculation will make this fps drop. I will try the ESp32 to have one core focusing on the screen and the other one on the application to try to keep 55fps. But otherwise I will as you propose move to a teensy with wifi shield. Thank you for your advice

You’re welcome! :slight_smile:

I love the esp8266 too. The price, speed, available RAM and flash space make a very nice combination. But I don’t need that Wifi feature. :slight_smile:
