I’m trying to get four p9813 lines out of a single teensy 3.1 at a decent speed… The hack at https://github.com/FastLED/FastLED/wiki/SPI-Hardware-or-Bit-banging#getting-four-hardware-spi-lines-for-the-apa102-out-of-the-teensy-3031 seems to work fine on this chipset for me, but I’m curious if anyone else has attempted it?
Just to be explicit, here’s how I’m adding the strips…
LEDS.addLeds<P9813, 7, 13, RGB, DATA_RATE_MHZ(15)>(leds_one, LED_COUNT);
LEDS.addLeds<P9813, 7, 14, RGB, DATA_RATE_MHZ(15)>(leds_two, LED_COUNT);
LEDS.addLeds<P9813, 11, 13, RGB, DATA_RATE_MHZ(15)>(leds_three, LED_COUNT);
LEDS.addLeds<P9813, 11, 14, RGB, DATA_RATE_MHZ(15)>(leds_four, LED_COUNT);
