Since debugging on every device is completely different, a DBG macro is
|
|
implemented. On Linux for example, this macro will print the string given
|
|
to the screen (using printf). On AVR, it will send debug strings through the
|
|
UART. For compatibility with other devices, it is necessary that you always use
|
|
the DBG-macro instead of a device-specific debugging commands.\newline
|
|
\newline
|
|
Because AVR-GCC puts strings in sram memory by default, every string should be
|
|
surrounded by the TXT-macro. On AVR, this macro will put the string in program
|
|
memory (flash), on any other device, this macro will be ignored.\newline
|
|
\newline
|
|
Example of a debug string:\\
|
|
\code{DBG((TXT("This is test nr \%d of \%d.$\backslash$n"),id,total));}
|
|
|
|
\subsubsection{Debugging on Linux}
|
|
On linux, debugging strings are sent to stdout using printf.\newline
|
|
\newline
|
|
To enable debugging, set DEBUG in \filename{config.h}.
|
|
\subsubsection{Debugging on AVR}
|
|
On AVR, debugging strings are sent through the UART and can be read using
|
|
a terminal like minicom (linux) or hyperterminal (windows). Standard, the
|
|
first UART is used, but this can be changed in \filename{debug.c} to the
|
|
second UART.\newline
|
|
\newline
|
|
To enable debugging:
|
|
\begin{itemize}
|
|
\item{Set DEBUG in \filename{config.h}}
|
|
\item{Set CLK to the clock speed of your AVR in \filename{config.h}}
|
|
\item{Set BAUDRATE to the baudrate you want in \filename{config.h}}
|
|
\item{Initialize debugging in your program by calling \code{debug\_init()}}
|
|
\end{itemize}
|
|
Remark: when you use the serial port in your main program, make sure you
|
|
use a different UART than the one efsl is using when sending debug string.
|
|
\subsubsection{Debugging on DSP}
|
|
On DSP, debugging strings are sent to Code Composer using the printf function.

To enable debugging, set DEBUG in \filename{config.h}.\newline

Remark: this will only work when using a DSK-kit.
