IoT Hardware
Introduction
The Internet of Things IoT
hardware subsystem provides APIs for operating IoT devices, including flash, general-purpose input/output GPIO
, Inter-Integrated Circuit I2C
, pulse width modulation PWM
, universal asynchronous receiver-transmitter UART
, and watchdog APIs.

Constraints
The IoT hardware subsystem is compiled using the C language. Currently, only the Hi3861 development board is supported. If you want to use other chips, you need to implement OpenHarmony APIs.
