90-30 Bit Operations

Hi, I'm a "bit" confused with shift registers for the 90-30, cpu 323.

I'm trying to start a group of 16 motors in sequence using a shift register. How do I write the %R's to %Q's?

Thanks

Hi you can simply use MOVE

make sure you target a byte boundary for your %M bits

eg %M0001 / %M0016 etc

why not use shift bits. Once you pick Shift Register change type to bits instead of word.

Try this. Every scan in which both %M0001 and %M0002 are true and %R00001 has the value 1, you will shift the bit pattern of the sixteen bits starting at %Q0001 by one place and move a 1 into the vacated LSB.

You can clear all sixteen bits by putting the value 16 into %R00001, turning %M0002 off and turning %M0001 on.
