Error Handling

Detailed Description

Definitions related to error handling for Class B tests.

In order to make the library as flexible as possible, the user can configure the response to the different errors that can appear during the tests. Therefore, the user is responsible to handle the errors in a way such that the application is safe and reliable.

Global variables defined in the main application.
NO_INIT volatile uint8_t	classb_error
	The global error flag in the examples.

Error handlers for Class B tests.
These are the statements that should be run if a test fails. Note: The statements need to be declared as: do{<statements>}while(0) or similar. Example: in order to hang the device it is possible to set do{}while(1).
#define	CLASSB_ERROR_HANDLER_ANALOG()   do{classb_error = 1;}while(0)
	Error handler for the ADC, DAC and analog multiplexer test.
#define	CLASSB_ERROR_HANDLER_CRC()   do{classb_error = 1;}while(0)
	Error handler for the CRC test.
#define	CLASSB_ERROR_HANDLER_FREQ()   do{classb_error = 1;}while(0)
	Error handler for the CPU frequency test.
#define	CLASSB_ERROR_HANDLER_INTERRUPT()   do{classb_error = 1;}while(0)
	Error handler for the interrupt monitor.
#define	CLASSB_ERROR_HANDLER_REGISTERS()   do{classb_error = 1;}while(0)
	Error handler for the CPU registers test.
#define	CLASSB_ERROR_HANDLER_SRAM()   do{classb_error = 1;}while(0)
	Error handler for the SRAM test.
#define	CLASSB_ERROR_HANDLER_WDT()   do{}while(1)
	Error handler for watchdog timer test.

Configurable actions and conditions for Class B tests.
Some test have a configurable behavior. Note: The conditions should be declared as: (<condition>). Statements need to be declared as: do{<statements>}while(0) or similar. Example: in order to hang the device it is possible to set: do{}while(1).
#define	CLASSB_CONDITION1_INTERRUPT   (!classb_error)
	Condition to assign a new state.
#define	CLASSB_CONDITION2_INTERRUPT   (classb_error)
	Condition to stop checking interrupts within the monitor.
#define	CLASSB_ACTIONS_RTC()   ;
	Configurable actions in the RTC interrupt.
#define	CLASSB_ACTIONS_WDT_RUNTIME_FAILURE()
	First group of configurable actions in the watchdog timer test.
#define	CLASSB_ACTIONS_WDT_OTHER_FAILURE()   do{}while(0)
	Second group of configurable actions in the watchdog timer test.
