2.1.1 MCU and Hardware Design Dependent Configurations

The following are the configuration files that must be modified based on the hardware design.

  1. conf_winc.h

    This configuration file has ATWINC15x0 SPI and pin mapping settings. The user needs to modify these configurations based on the hardware design.

    Figure 2-1. Hardware Design
    Figure 2-2. Software Code Setup
  2. conf_spi.h

    The Host MCU and ATWINC15x0 are connected over SPI. The Host MCU acts as the master while communicating to the ATWINC15x0 module. The user needs to enable the MCU master mode configuration using CONF_SPI_MASTER_ENABLE.

    Figure 2-3. conf_spi.h
  3. conf_exint.h

    The ATWINC15x0 uses an external interrupt for changing the notification. Enable the external interrupt clock source input to use the external interrupt.

  4. Conf_clock.h

    The user needs to modify the clock configuration based on the hardware design.
