How to use GPB0 - 7

[Rahatmaini]

On the MCP23017 chip, I know how to use the GPA0 - 7 expansion pins, but I do not know how to use the GPB pins.

Here is how GPA pins are initialized

Code: Select all

mcp.pinMode(0, OUTPUT);

Now how do I use the other 8 pins of the 16 pin expander?

Thanks Adafruit

pinMode accepts pin numbers from 0 to 15. GPIOA are 0 through 7, GPIOB are 8 through 15.
