Expand description

MCP23017 register map.

Note: This operates the chip in IOCON.BANK=0 mode, i.e. even register addresses are bank 0. This driver does not set IOCON.BANK, but the factory default is 0 and this driver does not change that value.

See the datasheet for more information on the device.

impl Map for Mcp23017

source

fn map(self, reg: Register) -> (u8, usize)

A way to map a named register (Register) and pin (from Pin, depending on the variant) to a register address and bit index. This may depend on the number of IO banks, the way the banks are ordered in memory, and even the current configuration (IOCON.BANK). Read more
