# I2c Slave Example Code

## Project Name: I2c_Slave_Demo

---

## Function description

This project is designed to demonstrate the configuration and use of the I2C module as a slave:
- **I2c_Slave_Demo**: 
  - I2c slave waits for i2c master to send 8 bytes of data.
  - After the reception is completed, wait for the i2c master to read 8 bytes of data.

## Setup

+ ***Step1***: Open the project.yct with the YCT tool, config the toolchain per your required(by default, the VS code + GCC are used)
+ ***Step2***: Generate the codes, you can change the configurations if needed(to adapt to your own HW design), if so, please ensure all the modifications are OK with no any errors exist before generating the code.
+ ***Step3***: Open the generated project with VS code/IAR/Keil IDE per your selected.
+ ***Step4***: Compile the project, power on the EVB and download it to the EVB via the available debugger, such as a J-LINK debugger probe.
+ ***Step5***: At last, enjoy the demo example.
