add support for PCA9554PW Port Expander #273

Closed maromme closed 5 months ago

maromme commented 1 year ago

Hi, I added support for the port expander (https://shop.m5stack.com/products/official-extend-serial-i-o-unit). For me that is the basis adding the x85a feature in future. You just have to install that https://github.com/AD0ND/PCA9554 library first. Then it's working fine for me. Rememer that the default SG1 and SG2 ports are used by the i2c communication. Change them to what ever suits you on the expander. As it's my first pull request, please tell me if i did something wrong... Yours, markus

Thanks @maromme for this, Can you comment it by default in setup.h, and add some comments?

Thanks
