SYSBIOS Interrupt Assertion Testing

Larry Waterson

Other Parts Discussed in Thread: SYSBIOS

I'm currently porting CCS version 3.0 code to CCS version 5.2 using SYSBIOS. The previous code used a function IRQ_test() that would allow you to test the interrupt flag to see if it is asserted. I have not able to find a comparable function (API) for SYSBIOS, I'm using "ti/sysbios/hal/Hwi.h" for my current interrupt API functions. Please help me with this issue.

Larry,

THe code you were using was part of the CSL; not BIOS; so hence the reason it's not showing up in SYSBIOS. I'll look for an equivalent- can you tell me what part this is for?

Larry,

So would HWI_post(Uint IntNum) work for you? It's specifically designed for interrupt testing.

My understanding of the Hwi_post() is that it generates an interrupt. I'm looking of a function that would be more like Hwi_wait() that would block the program until the interrupt is asserted.

I think my only hope is to write an assembly language program that will sample the IFR.

Thanks.

Larry,

Sorry I misunderstood; but given the new revelation; I think ou can still do this without assembly. The c6x.h file is in the ccsv5/tools/compiler/c6000_YOURVERSIONHERE/include/c6x.h

Just include this file, and IFR is defined in there, so you can, in C, do something like:

while((IFR & MASK) == 0) or whatever you like.
