binary # output on i/o

zafh15a

I would like to have a variable expressed as a binary # in parallel on the I/O pins. the variable will be incremented or decremented by user inputs. so I would like the var to be input as a decimal # but then expressed in a 1 byte output on pins

ex:
user inputs··· 1

outputs go
················· 0-0
················· 1-0
··················2-0
··················3-0
··················4-0
················· 5-0
··················6-0
················· 7-1

I can do all of this with lookup table but at the expense of memory. Will the stamp perform this function thru its command set for me somehow.

Well, without looking in the Basic Stamp manual, here goes.

VAR BYTE yourNumber

out0 = yourNumber.bit7
out1 = yourNUmber.bit6
out2 = yourNUmber.bit5
out3 = yourNUmber.bit4
out4 = yourNUmber.bit3
out5 = yourNUmber.bit2
out6 = yourNUmber.bit1
out7 = yourNUmber.bit0

Or something like that...

The ideal instruction for this is the OUTS register, the OUTS register (look under Memory and Variables in the PBasic help file) can switch anywhere between 1 and 16 output pins simultaneously with one line of code

OUTA=3· would result in 0011 on P0 to P3
