 Forum: General CCS C Discussion Posted: Wed Jun 18, 2014 6:24 am Subject: Protothreads on CCS |
| In CCS a short is defined as 1 bit while the programmers of this library assumed it to be 8 bit or larger.
This can be fixed by replacing all 'short' types by standard 'int' or use the #type directiv ... |

| The key difference is INT_RA only affects the IOC while INT_DEFAULT affects more interrupts than just the IOC, so you can sometimes introduce bugs into places where you didn't mean to using INT_DEFAU ... | |

| Why not use #int_ra instead of #int_default?
That appears to be the int handler for IOC on the pic12F683 You'll still have to do masking, but that is normal for IOC since the hardware forces tha ... |
