# PPI Parallel ADC example
## Overview

This example project shows read data from external parallel ADC by PPI, using asynchronous SRAM interface to access.

The PPI memory address region is 0xF8000000~0xFFFFFFFF, base address should be aligned by 1MB.

## Board Setting

External parallel ADC module is required. The tested parallel ADC is MS9280.

## Running the example

When the project runs correctly, and the serial port terminal will output the following information:
```
