Porting Notes

This file defines and consolidates various standardized data types required by the Platform Peripheral API
Generic Platform Peripheral data types are defined in this file
MCU-specific data types are defined in <WICED-SDK>/platform/MCU/<MCU_family>/platform_mcu_peripheral.h
platform_mcu_peripheral.h may include declarations, definitions, and function prototypes which are local to the MCU family
The following table outlines the structures that need to be defined in platform_mcu_peripheral.h: +---------------------—+--------------------—+ | Name | Description | +---------------------—+--------------------—+ | platform_gpio_t | GPIO interface | | platform_uart_t | UART interface | | platform_uart_driver_t | UART driver interface | | platform_spi_t | SPI interface | | platform_i2c_t | I2C interface | | platform_pwm_t | PWM interface | | platform_adc_t | ADC interface | +---------------------—+--------------------—+
