Port.Bit on X2

Jeremy Leach · Jul 14, 2009

I was hoping to use a command like:

Code:

Pulsout B.B0,10000

But it doesn't like the variable in the BIT position

But in the manual, for Pulsout it says

Pin is a variable/constant (0-7) which specifies the i/o pin to use.

Hmmm, pity ...

You can't mix a variable into a port.bit name, but you can use a variable as a pin name

Code:

b1 = C.0
pulsout b1,10000

Code:

b1 = c.0

So, what is the actual value that is placed in b1? What is the numbering system? I'm using the code to calculate the bit to use

b.0 to b.7 are 0-7
c.0 to c.7 are 8-15
a.0 - a.7 are 16-23
d.0 - d.7 are 24-31

Ah, great thanks !

Which means you can do things like this ...

For b0 = B.0 To B.7
Toggle b0
Next

For b0 = 0 To 7
b1 = B.0 + b0
Toggle b1
Next

Hah,

So that's how that works.

Thanks

So can you do this ?

symbol LCD_RS = b1
b1=C.0

high LCD_RS

Yes, you CAN do that.
