PNUT issue with INA?

rjo__

When I do this it works fine

setb     outa, #25
setb    dira,#25

when I do this it works fine

mov   temp,#0
wrlut ##$FFFFF,temp

when I do this it works fine

mov   inna,##$FFFFF
mov   temp,#0
wrlut inna,temp

BUT not when I do this...

mov   inna,INA
mov   temp,#0
wrlut inna,temp

Gives $FFFF FFFF
Using P123 A7 with fix
I have tried every addressing mode for INA... so that isn't it. So, what is it?

What is INA connected to on the hardware side? If none of the pins go anywhere, then $FFFF_FFFF would not be a suprising value to get.

I have two input pins connected to +V3.3 on the header and one output pin connected to an LED... which lights correctly. The rest are floating. The +V source is fine.

I'm hoping that it is just an issue with my board. But it is weird enough that I thought it was worth mentioning.

When I look at INB in a similar way... pins 15 and 16 are the only ones that change to zero... even though nothing is hooked up:) V+ to other pins has no effect.

Do I have to declare pins as inputs? My understanding is "no" and that INB should show the states without any fuss... as on the P1.

I have serial working fine... using pins 62 and 63. And I have video working fine in the same program.

At the beginning of your code, put a WAITX ##25_000_000 and see if that works for you. Several weeks back, there was an issue reading inputs unless a large delay was inserted. I am not aware of a resolution to that issue, so you may be encountering it here.

INA is working Ok on my P123-A7 board
All pins tested Ok as inputs (INA 0..31)

Thanks guys. I did what I was supposed to do.... have a beer and go to bed.

This morning, I retried everything and get the same. I have to believe that it is the board. Problem is that every other time I have believed this (except once)... it wasn't the board; it was me.

if I look at #INA, I do get $1FE, so INA is where it is supposed to be;)

rjo_, are you still experiencing trouble?

rjo__

nope:)

neglected to pull down my pins. Which is probably the mistake I was also making with my P1V project. BUT I still can't figure out how to rotate (x32,y32) by theta

Use QVECTOR to convert your x,y values to Ro,theta.
Use QFRAC to convert angles to 32 bit values.
and use QROTATE to get back x, y values from a R0,theta pair.

Something like this:

		qvector	#50,#50		'x=50,y=50
		getqx	ro		'ro = $47 = 71
		getqy	theta		'theta = $20000000 = 45 degrees

		qfrac	#12,#360	'convert 12 degrees
		getqx	angle		'angle = $08888888

		qrotate	ro,angle
		getqx	new_x		'new_x = $45
		getqy	new_y		'new_y = $f

Hope this helps

I thought I tried everything:)

SETQ Y
QVECTOR X,ANGLE
...
SETQ Y
QROTATE X,ANGLE

If the SETQ is missing, then 0 is used for Y.
