|

|
|
///
|
| 35 |
|
|
/// This module provides definitions and functions for using the Debug Unit
|
| 36 |
|
|
/// (DBGU).
|
| 37 |
|
|
///
|
| 38 |
|
|
/// It also overloads the fputc(), fputs() & putchar() functions so the printf()
|
| 39 |
|
|
/// method outputs its data on the DBGU. This behavior can be suppressed by
|
| 40 |
|
|
/// defining NOFPUT during compilation.
|
| 41 |
|
|
///
|
| 42 |
|
|
/// !Usage
|
| 43 |
|
|
///
|
| 44 |
|
|
/// -# Enable the DBGU pins (see pio & board.h).
|
| 45 |
|
|
/// -# Configure the DBGU using DBGU_Configure with the desired operating mode.
|
| 46 |
|
|
/// -# Send characters using DBGU_PutChar() or the printf() method.
|
| 47 |
|
|
/// -# Receive characters using DBGU_GetChar().
|
| 48 |
|
|
///
|
| 49 |
|
|
/// \note Unless specified, all the functions defined here operate synchronously;
|
| 50 |
|
|
/// i.e. they all wait the data is sent/received before returning.
