Encountered a strange behaviour Adafruit Pro Trinket 5V
I’m using 2 APA102 strips and had the sketch running on an UNO
DATA_PIN_L 6
CLOCK_PIN_L 8
DATA_PIN_R 7
CLOCK_PIN_R 9
On the Trinket I changed to
DATA_PIN_L 6
CLOCK_PIN_L 8
DATA_PIN_R 9
CLOCK_PIN_R 10
but no LED lit up.
CLOCK_PIN 3 and DATA_PIN 4 works.
Experimented and found that it works when I share the CLOCK_PIN 3 and assign different DATA_PINS
DATA_PIN_L 6
CLOCK_PIN_L 3
DATA_PIN_R 8
CLOCK_PIN_R 3
