1.3.2.3 Configuring the Library

I²C Bit Bang Library should be configured via MCC. The following figures show the MCC configuration window for I²C Bit Bang and brief description.

I²C Bit Bang Configuration:

I²C Bit Bang Configuration With I²C Driver:

Configuration Options

• I2CBB Operation Mode

  • Indicates the I²C mode used by the library

  • The I²C Bit Bang library only supports Host mode

• I2CBB Clock Speed:

  • Specifies the I²C clock speed in Hz

• I2CBB Data Pin:

  • Specifies the GPIO pin number to be configured as I²C Data Line

  • The specified pin has to be configured as GPIO input and open drain has to be enabled

• I2CBB Clock Pin:

  • Specifies the GPIO pin number to be configured as I²C Clock Line

  • The specified pin has to be configured as GPIO input and open drain has to be enabled

• Include Force Write I²C Function:

  • When enabled generates the I²C force write API which can be used to perform force writes to I²C client. The generated API ignores any NACK from client during the write.

  • Used in Host mode only.
