IO

This document is intended to help beginners quickly become familiar with the peripherals of RTK MCU. It introduces various peripherals, including PINMUX, PAD, GPIO, TIMER, PWM, UART, GDMA, I2C, SPI, IR, RTC, LPC, 3-wire SPI, CapTouch, ADC, QDEC, KeyScan, SLEEP LED, I2S, SDIO, CAN peripherals. Additionally, this document covers an IO demo project, peripheral functions, peripheral operation flow, and corresponding demo code.

Each chapter is mainly divided into the following aspects to introduce peripherals.

• Peripheral Function Description

• Introduction to Protocols

• Basic Information of Peripherals

• Operation Flow

• Sample Code Description
