It turns out there are only four intrinsic functions used in the TI Sports
Watch source code. I created my own intrinsics.c source file. It is
included below. I have implemented three of the four functions. The
remaining one should not be hard to do, I just haven't gotten to it yet.
========= begin code ====================
// intrinsics.c
#include<intrinsics.h>
//__delay_cycles used in main.c, rf1a.c, bsp_board.c
void __delay_cycles(unsigned long __cycles)
{
/* TODO: PFS needs to implement body of __delay_cycles
}
//__set_interrupt_state used in bsp_msp430_defs.h, rf1a.c
void __set_interrupt_state(istate_t state)
{
__asm__("bis %0,r2" : : "ir" ((uint16_t) state));
}
//__even_in_range used in adc12.c
unsigned short __even_in_range(unsigned short __value, unsigned short
__bound)
{
return (__value<= __bound&& __value>=0);
}
//__get_interrupt_state used in bsp_msp430_defs.h, rf1a.c
istate_t __get_interrupt_state(void)
{
return(READ_SR&0x0008);
}
============= end code ====================
Since I have linking problems, I have not been able to actually test the
functions, but I am now getting a clean compile with no errors. I am,
however, getting a compile warning from this section of signal.h:
#if defined(__MSP430X__)
#define INTERRUPT_VECTOR_SLOTS 32
#define RESET_VECTOR 62
#elif defined(__MSP430X2__)
Line 39 ====>> #warning X2 ist da<<======
#define INTERRUPT_VECTOR_SLOTS 64
#define RESET_VECTOR 126
#else
#define INTERRUPT_VECTOR_SLOTS 16
#define RESET_VECTOR 30
#endif
I'm not sure if I need to be concerned about this warning.
