Hi,
I am currently debugging my program. It all went ok until the ADC initialisation function InitAdc () is called.
Before converting, there is a delay function DELAY_US(ADC_usDELAY)
The assembly language is
_DSP28x_usDelay:
SUB ACC,#1
BF _DSP28x_usDelay,GEQ ;; Loop if ACC >= 0
LRETR
After this, my program fell into an infinte loop:
interrupt void ILLEGAL_ISR(void) // Illegal operation TRAP
{
// Insert ISR Code here
// Next two lines for debug only to halt the processor here
// Remove after inserting ISR Code
asm(" ESTOP0");
for(;;);
}
Can anyone provide any suggestion that help me get out of the trap please? Do I just remove the last two lines as suggested in the comments?
The device I am using is F28027 Piccolo Launchpad.
Many thanks.
Jingzhe
