That's odd.

Is strobe sitting at 1 or at 0?

Possibly try swapping all the strobe=1 for strobe=0 and vice-versa. Maybe it's best to write the data and address, pause 1mS write the strobe.

in show hal I watch strobe and it is off longer than is on but is toggling just really slow and its on only for an instant. I can never get the watch screen to say true though

the max jitter on this laptop is 6 figures. would it be better to do a for loop so the strobe stays true until something changes?

It seems to strobe as expected here:

And that is on a VM with hilarious latency:

The raw_writer is definitely added to a thread (it must be if you see the state toggling 20/10)

I was looking at the hm2 pins not raw. but now that I have changed that I see that state is working but strobe, data, and address are not. perhaps I messed something up in the comp. I've attached it

Actually, something seems to be wrong with the way that the data is being calculated.

65536 is not the right value for 000011 on the inputs.

Try:
Code:
data = in(0) + (in(1)<<1) + (in(2)<<2) + (in(3)<<3) + (in(4)<<4) + (in(5)<<5);

(and, actually, all those "in" pins really should be called "out")

Yes, and it should be 0x001. I made another mistake to do with the order of calculation of << and +

Change the data calculation according to my previous post, and if that doesn't work, try exchanging the strobe=0 and strobe=1 lines throughout.

I just changed all the in to out in the equation and compiled again. get the same result. When run halcompile does it rewrite or should i remove the old .so
