Are there any way to connect 2 Unicorn HAT HD to one raspberry pi？I am using Unicorn HAT HD at Raspberry Pi GPIO Pinout this product, and connect it with raspberry pi zero w 2. I want to connnect it to two different Unicorn HAT HD screem, and program it to achieve differet effect at same time. Are there any way to do it？ If not, what is the best way to contral two screen and synchronize those two?
No, not easily if at all. You’d would have to wire them up so they each use a different SPI Chip Select pin. One on CE0 and one on CE1. That’s doable with perf boards, but the software won’t play nice. It’s coded to work with the stock setup of one hat on the default pins.
It’s easy to do with SPI LCD’s but the Unicorn Hat is a different beast.
To do what you want you’d have to go to an Ubercorn or something similar.
