Hibernate Example (hibernate)

+//! +//! An example to demonstrate the use of the Hibernation module. The user +//! can put the microcontroller in hibernation by pressing the select +//! button. The microcontroller will then wake on its own after 5 seconds, +//! or immediately if the user presses the select button again.

Hibernation module so that it can be retrieved when the microcontroller +//! wakes. +// +//***************************************************************************** + +//***************************************************************************** +// +// Macros to convert character based display rows and columns into the pixel +// based X and Y coordinates needed for display drawing functions. +// +//***************************************************************************** +#define Col(c) ((c) * 6) +#define Row(r) ((r) * 8) + +//***************************************************************************** +// +// A counter that counts the number of ticks of the SysTick interrupt. +// +//***************************************************************************** +volatile uint32_t g_ui32SysTickCount = 0; + +//***************************************************************************** +// +// A buffer to hold character strings that will be printed to the display. +// +//***************************************************************************** +static char g_pcBuf[40]; + +//***************************************************************************** +// +// Text that will be displayed if there is an error. +// +//***************************************************************************** +static char *g_pcErrorText[] = +{ + "The controller", + "did not enter", + "hibernate mode.", + "---------------------", + " PRESS BUTTON", + " TO RESTART", + 0 +}; + +//***************************************************************************** +// +// A flag to indicate the select button was pressed. +// +//***************************************************************************** +static volatile bool bSelectPressed = 0; + +//***************************************************************************** +// +// The error routine that is called if the driver library encounters an error. +// +//***************************************************************************** +#ifdef DEBUG +void +__error__(char *pcFilename, uint32_t ui32Line) +{ +} +#endif + +//***************************************************************************** +// +// Delay a certain number of SysTick timer ticks. +// +//***************************************************************************** +void +SysTickWait(uint32_t ui32Ticks) +{ + ui32Ticks += g_ui32SysTickCount; + while(g_ui32SysTickCount <= ui32Ticks) + { + } +} + +//***************************************************************************** +// +// The SysTick handler.
