# Project Name: CddUart_Demo

---
## Functional Description

+ This Demo showcases the usage of CddUart API and demonstrates how to configure buffers using CddUart_SetBuffer() API for continuous transmission/reception.
+ The demonstration utilizes LinFlexd2 in UART mode with the following configuration:
  ***115200 baud rate, 8 data bits, 1 stop bit, and no parity***.

---
## Operation Instructions

+ ***Step 1***: Launch the sample YCT project file (**CddUart_Demo.yct**) using YCT tool and configure the toolchain as needed (default: VS Code + GCC).
+ ***Step 2***: Generate the code. Modify configurations if necessary (to accommodate your hardware design), ensuring all changes are correct and error-free before code generation.
+ ***Step 3***: Open the generated project in your preferred development environment (VS Code/IAR/Keil IDE) based on your configuration.
+ ***Step 4***: Compile the project, power on the EVB, and flash the compiled executable using an available debugger (e.g., J-Link debug probe).
+ ***Step 5***: Power off the board, disconnect JTAG/SWD debug cables, then power on again.
+ ***Step 6***: Configure a serial terminal with 115200 baud rate, 8 data bits, 1 stop bit, and no parity. Run the demo code and send 5 bytes of data to the MCU, which will echo back the received 5 bytes.
