Astra SRSDK Driver Library

Introduction

The Astra SRSDK Driver Library provides low-level access to the hardware peripherals of Synaptics SoCs. It is designed to offer a consistent API across supported devices, helping developers accelerate embedded system development.

This documentation covers two main areas:

• Common, reusable driver APIs (platform-independent)
• SoC-specific documentation (pin mappings, registers, interrupts, etc.)

Sections

• Astra SRSDK API Reference
• Astra SRSDK Hardware Identifiers

Supported Drivers

The following drivers are included in the SDK:

• UART: Universal Asynchronous Receiver/Transmitter interface for serial communication.
• I2C: Inter-Integrated Circuit controller for communication with I2C slave devices.
• SPI: Serial Interface for high-speed synchronous data transfer.
• SDIO: Secure Digital Input Output interface for SD cards and similar devices.
• Clock: Clock management and configuration APIs.
• GPIO: General-Purpose Input/Output configuration and control.
• Pinmux: Pin multiplexing and alternate function configuration.
• DMA: Direct Memory Access controller for managing high-performance data transfers between memory and peripherals.
