Class GpioBank - Banked General Purpose Input Output

There are 54 GPIOs named GPIO0 through GPIO53.

They are split into two banks. Bank 1 consists of GPIO0 through GPIO31. Bank 2 consists of GPIO32 through GPIO53.

All the GPIOs which are safe for the user to read and write are in bank 1. Not all GPIOs in bank 1 are safe though, it depends on the board type.

A GpioBank object can be used to read or write up to 32 GPIOs as one operation.

Methods

• GpioBank(bank)
• read()
• set(bits)
• clear(bits)
• bank()

Constants

• BANK1
• BANK2

Methods

GpioBank(bank)

• bank - BANK1 or BANK2 (optional, defaults to BANK1)

Returns a new GpioBank object for accessing up to 32 GPIOs as one operation.

read()

Returns the current level of all GPIOs in the bank.

set(bits)

bits - a bit mask of the the GPIOs to set to 1

For each GPIO in the bank, sets the GPIO level to 1 if the corresponding bit in bits is set. Returns this.

clear(bits)

bits - a bit mask of the the GPIOs to clear or set to 0

For each GPIO in the bank, sets the GPIO level to 0 if the corresponding bit in bits is set. Returns this.

bank()

Returns the bank identifier (BANK1 or BANK2.)

Constants

BANK1

Identifies bank 1.

BANK2

Identifies bank 2.
