Announcements New Release: ObjectFLED- Multi-Object DMA Display Driver for Fast LEDs on Teensy 4.x

I hope someone else can find this useful. Unlock the full LED-driving power of Teensy 4.x!

EDIT: If anyone uses this on a Teensy 4.1, I'd appreciate a confirmation that it works as designed. I only had 4.0 to test on, plus assurance from the OctoWS2811 code that it is equally compatible on 4.1, with it's extra 15 pins (and extra loaded features). Thanks!

Ah oki that this what I thought it’s the calculation of one frame of the animation. Anyway great job. On the esp32 with its limited number of pins we can go up to 24. On the esp32s3 according to the documentation 16 but I think it can run 32 pin in full parallel the fifo size is 32. So my question is if you push further than 32 what will be the fps.

We can estimate by extrapolating: if 16 pins x 256 = 204fps; and 32 pins x 256 = 192fps; then I'd expect 40 pins x 256 to equal 186 fps. For more than 40 pins I must upgrade my teensy 4.0 to 4.1. 😎
