#103448 - inconsistent Responding to: ???'s previous message |
When the conversion is through, interrupt 10's ISR turns off the ADCI bit, and sets a global variable to true. void adc_intr() interrupt 10 _naked using 0 {
_asm
push acc
_endasm;
ADCON &= 0xc0;
_asm
pop acc
_endasm;
}As Erik said, we see no such thing as setting a global variable. I keep being amazed how people stick to SDCC 2.4.0 when 2.5.0 is out for over half a year. Development is at 2.5.4. Maybe you have to pay for SDCC where you live? B.t.w. Erik, SDCC uses a peephole optimizer to replace small pieces of asm code by other more optimal pieces of code. Along the way it documents this with comments in the asm code. Have a look at the rules if you're interested: http://cvs.sourceforge.net/viewcvs.p...9&view=log |
