Detailed Description

If your application requires it, you can change the default settings for kernel and drivers.

Kernel settings are in miosix/kernel/kernel_settings.h,
while all other settings are in miosix/miosix_settings.h

Don't forget to rebuild the kernel if you make modifications to these settings.

Define Documentation

#define JTAG_DISABLE_SLEEP

JTAG debuggers lose communication with the device if it enters sleep mode, so to use debugging it is necessary to disble sleep in the idle thread. By default it is not defined (idle thrad calls sleep).

#define WAKEUP_DELAY

Uncomment if you want that to resume after shutdown, the user must hold down the button for two seconds. Comment if you want instant resume. By default it is not defined (no wakeup delay)

#define WITH_BOOTLOG

Uncomment to print bootlogs. By default it is defined (bootlogs are printed)

#define WITH_CPU_METER

If defined the function cpu_load() becomes available. By default it is defined (cpu_load() is available)

#define WITH_ERRLOG

Uncomment for debug information on error. By default it is defined (error information is printed)

#define WITH_FILESYSTEM

Uncomment to include filesystem support. By default it is defined (filesystem support is enabled)

#define WITH_INIT_CALLBACKS

Uncomment to enable support for initialization and shutdown callbacks. If enabled, the user must supply those functions:

   void callback_startup();
   void callback_shutdown(); 

By default it is defined (init callbacks are provided in callbacks.cpp)

#define WITH_RTC

Uncomment to enable support for RTC. Time-related functions depend on it. By default it is defined (RTC is active)

#define WITH_STDIN_BUFFER

If defined, incoming data fron the serial port will be buffered prior to being delivered to stdin related functions (scanf, fgets, cin...). Buffer is flushen on newline or when full. This has a behaviour more similar to desktop operating systems but requires 1KB of RAM for the buffer. By default it is not defined (stdin is unbuffered)
