Purpose
The USART example shows the how to transfer/receive buffer over USART.
Requirements
This package can be used with SAM V71 Xplained Ultra board.
Description
The demonstration program transfer a buffer via USART in local loopback mode and receives the buffer.
Usage
- Build the program and download it inside the SAM V71 Xplained Ultra board. Please refer to the Getting Started with SAM V71 Microcontrollers.pdf
- On the computer, open and configure a terminal application (e.g. HyperTerminal on Microsoft Windows) with these settings:
- 115200 bauds
- 8 bits of data
- No parity
- 1 stop bit
- No flow control
- Start the application.
- In the terminal window, the following text should appear (values depend on the board and chip used):
-- USART Example Example xxx --
-- xxxxxx-xx
-- Compiled: xxx xx xxxx xx:xx:xx --
Menu :
========================
UART is Configured in : LoopBack
D: Perform USART DMA LoopBack Normal transfer
T: Perform USART DMA Normal transfer(remote loopback)
H: Display menu
- The user can then choose any of the available options to perform the described action.
