Q: Why does my xxx_SW_I2C() device not work with my other I2C devices
Q: Why does my xxx_SW_I2C() device not work with my other I2C devices?
A: SW_I2C emulates I2C with digitalWrite(), which will have a conflict with other
I2C devices at the same pins. There are two options: (A) use xxx_HW_I2C() or
(B) use different pins with xxx_SW_I2C()
Q: My display has a pin labled as "A0" (or "RS"). How to connect this pin?
