Macros for debugging use.
#define JTAG_DEBUG_ASSERT | ( | x ) | MACROS{ if (!(x)) { JTAG_DEBUG_BREAK(); } }MACROE |
Macro for testing condition "x" and breaking via JTAG_DEBUG_BREAK() if the condition is false.
#define JTAG_DEBUG_BREAK | ( | ) | __asm__ volatile ("BREAK" ::) |
Defines an explicit JTAG break point in the resulting binary via the ASM BREAK statement. When a JTAG is used, this causes the program execution to halt when reached until manually resumed.
#define JTAG_DEBUG_POINT | ( | ) | __asm__ volatile ("NOP" ::) |
Defines a volatile NOP statement which cannot be optimized out by the compiler, and thus can always be set as a breakpoint in the resulting code. Useful for debugging purposes, where the optimiser removes/reorders code to the point where break points cannot reliably be set.
#define STDOUT_ASSERT | ( | x ) |
MACROS{ if (!(x)) { printf_P(PSTR("%s: Function \"%s\", Line %d: " \ "Assertion \"%s\" failed.\r\n"), \ __FILE__, __func__, __LINE__, #x); } }MACROE
Macro for testing condition "x" and writing debug data to the stdout stream if false. The stdout stream must be pre-initialized before this macro is run and linked to an output device, such as the AVR's USART peripheral.
The output takes the form "{FILENAME}: Function {FUNCTION NAME}, Line {LINE NUMBER}: Assertion {x} failed."
