This Forum is Dedicated For all The Object Oriented PIC Lovers .......... The concept behind OOPic is straight forward. Use preprogrammed multitasking Objects from a library of highly optimized Objects to do all the work of interacting with the hardware. Then write small scripts in Basic, C, or Java syntax styles to control the Objects. During operation, the Objects run continuously and simultaneously in the background while the scripts run in the foreground telling the objects what to do.

RE: [oopic] Re: where is everybody!

My book is called Digital Logic and Computer Operations by Baron and
Piccirilli published 1968 McGraw Hill. It's quite good. Is a little
confusing in some parts because some of the diagrams have labels on them
that aren't referred to in the text i.e. It has a block schematic of a
single pulse generator (like an oOneShot ?) with two terminals marked F and
G and makes now reference as to what that means. In one diagram the G
terminal is connected to the toggle switch of a set/reset type flip-flop but
in another diagram it had the F terminal connected. Do you know what they
mean?

Mike.

www.alibris.com has a LOT of used books. So just post the title and
author with or without the ISBN.

My fist book was "Logic Design with Integrated Circuits by Wickes
published in 1968 - I bought it in early '69. At that time RTL logic
was king of the heap and DTL was just coming into play. What an
exciting time!
