Hi,
I am wondering whether you could do a change on on your driver.
From my experience, with this APA102, the start frame with 32 x 0x00 is important and works.
But the 32 x 0xff is wrong even the datasheet tells you different.

I found out if you send (32 x 0x00) - n*4Byte (LED data) - (32 x 0x00 plus n/2 x 0x00) the frame will be displayed even you send only one time a frame.

For eg.
150 LEDs on one row and you need to light up only the first 100 LEDs.
You send (32 x 0x00) 100 x 4 Byte (57 x 0x00). Only the frst 100 LEDs are on.

If you send (32 x 0x00) 100 x 4 Byte (32 x 0xff) your 101 LED is on white and the
LEDs are on if you send the second frame.

Conclusion: End Frame (32 + n/2) * 0x00 will allow you sendonlyon times a frame and then+1 LED is off.

hi, so sorry to draw issue for my question , actually I'm Arduino user and try to make POV with ESP and APA102 ,however after couple of try , I find current version of FastLED does not support HW SPI for LED chip such as APA102, hence I've tried to look proper lib to drive APA102 on ESP, I really appreciated if you could guide me to proper APA102 lib on ESP can be added in Arduino IDE and support HW SPI?
