serial.h

Go to the documentation of this file.

/*
  serial.h - Contains definitions and function prototypes for the RS232 serial port
  author(s): pkv
  
  Directions:
  Call the initialization function for the serial port you wish to use.  Then, use
  either the provided functions or the stdio functions (fprintf, etc) to read and
  write characters to the serial ports.
  
  UART Mapping:
  usb_*() -> UART0
  xbee_*() -> UART1
  
  Options: (Add the following defines to your code to configure this library)
  #define USB_BAUD { 115200 | 9600 } <= pick ONE value from in here
  #define XBEE_BAUD { 115200 | 9600 } <= pick ONE value from in here
  #define USE_STDIO
  
  Note: If you enable USE_STDIO, the first init function that is called will 
  automatically be linked to stdin, stdout, and stderr.  To use the baud rate 
  commands, add something like the following to your code:
  
  #define FOO_BAUD 9600
  
  **UNLESS YOU KNOW WHAT YOU ARE DOING, PLEASE DO NOT CHANGE THIS FILE**
  Many, many other people use this file in their code.  If you change it, you will
  probably break all of their nice code.  You should not need to change anything in
  here, except to accomodate new hardware.
