AVR32 - USART Driver - SPI Example Documentation
This is the documentation for the data structures, functions, variables, defines, enums, and typedefs for the USART in SPI modes software driver.
It also comes bundled with an example. This example is a basic Write to Slave Mode example.
Example's operating mode:
- A message is displayed on the PC terminal ("Basic write in USART SPI Mode (press enter)")
- You may then type any character other than CR(Carriage Return) and it will be echoed back to the PC terminal.
- If you type a CR, the SPI write mode send data through SPI
- usart.c: USART driver and SPI support mode;
- usart.h: USART driver header file and SPI support mode;
- spi_example.c: SPI example application.
This software is written for GNU GCC for AVR32 and for IAR Embedded Workbench for Atmel AVR32. Other compilers may or may not work.
All AVR32 devices with a USART module can be used.
This example has been tested with the following configuration:
- EVK1100 evaluation kit or EVK1101 evalutation kit;
- CPU clock: 12 MHz;
- USART1 connected to a PC serial port via a standard RS232 DB9 cable;
- PC terminal settings:
- 57600 bps,
- 8 data bits,
- no parity bit,
- 1 stop bit,
- no flow control.
