# Project Name：CddI2c_Master_Demo


---


## Function description

This project is designed to demonstrate the MCAL CddI2c module config and usage:
- **CddI2c_Master_Demo**: 
  After reset, the demo project will initialize the I2c driver .Then test the the I2c driver as following:
 + After I2c init, I2C0 transmit data to eeprom.
 + I2C0 read data from eeprom .
 + Compare the I2C0 tx data and rx data are same or not.
 + ***The data can be transmitted or received in async mode or sync mode.***

<p style="text-align: center;"><strong>Note</strong></p>

- The bitrate = Frequency / (((MCLKCFG[LOW] + MCLKCFG[High] + 2 + ROUNDDOWN((2 + MFLTCFG[FLTSCL] + SCL_RISETIME) / 2^DIV)) * 2^DIV)).
- Since SCL_RISETIME is related to the electrical characteristics of the peripheral/external circuit, the default value used in the calculation of YtTools is 0.0, to improve the accuracy of the baud rate, please fill in according to the actual situation.

## Setup

+ ***Step1***: Open the CddI2c_Master_Demo.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.
