    Using 8051 for making a PLC

    Re: 8051 based PLC Update, Go to https://www.cq.cx/ladder.pl, open source PLC for PIC and AVR, now maybe 8051 too -- look in the Forum. Couple of uploads which may work with Amtel 8051's. Like other members thoughts.

    Do you believe that universe is built on some simple equations?

    Re: Do you believe? simple equations are reassuring and make us think we understand. I don't think the situation has changed much since I was a physics major -- back then they could solve the 2 body central force problem and hooks law. (Note, these are idealized case that do not reflect any...

    The next step in our understanding?

    I would like other member's thoughts on an especially interesting book: The Field, the quest for the secret force of the universe by Lynne McTaggart ISBN 978-0-06-143518-8 Our understanding has always struck me as incomplete and fragmented. This book doesn't plug all the holes or...

    Mayan Prophecy: What's your view?

    I find it very strang that the Mayan's should fixate on 2012 and that what we see happening in the world seem to correlate? Supposedly, the Mayan prophecy was derived from some insight about the cycles of the sun? It does appear to be getting hotter, but not because of the sun spot cycle...

    Using 8051 for making a PLC

    ladder para 8051 I just recently found the following link to some orphaned software that has source for a ladder program: https://www.desmet-c.com/sources.shtml Note that the executable supplied are for Atmel ATmega 1281 / Atmel ATmega 2561, but with source it might be able to be ported to...

    Diff between PLC's and microcontrollers

    Well, there are some simularities, but there are lots of historical and practicle differences. PLC's evolved out of early indusstral controls. There are certain things that are implied with a PLC: latency input/response time, isolations of inputs, ect. Also the languages that a PLC is...

    What is the embedded C and how does it differ from normal C?

    Re: Embedded C It appears that I submitted the same comment twice. Sorry about that, but I'll modify my dublicate posting to answer the question about sources of information about embedded C. Search for information on the 8051, PIC, and AVR. There are lots of ebooks for these micros...

    What is the embedded C and how does it differ from normal C?

    Re: Embedded C "C" as originially written was for developing operating systems on mini computers. The power and elegance of this tool soon made it very popular for all types of applications. It soon moved to the micro computers that were taking the place of the larger machines. In all these...

    Bad news for US Engineers

    Of course it is about profits! Bussiness for the most part are design of the growth model - make more and more money have more and more control. Problem is we live in a finite world. Moving to a lower wage country does increase profit marge and it may open new markets. It also avoids some...

    Can PIC work instead of PLC ?

    Re: PLC & PIC Just about amy micro can be used to take the place of PLC- often with improved efficiency and almost as goo reliability. However, the problem with using micros is that when problems develope only personnel familar with the micro can troubleshoot at the chip level. In real life...

    Which Programming Language do i need for...

    Based on the discussion so far I would sugest that you acquire a simple micro development board with normal components. Once you understand how to use the board and software, I think that most of you questions will be answered. I would suggest that you get one of the standard offerings based...

    What's the Best Linux For EDA tools ?

    Maybe everyone should keep and eye on SuSE, seems that they may be in a good possition in very near future if the SCO attack goes forward. Couple of good ref to article on the accquisition of SuSE by Novell and implications: https://eletters.eweek.com/zd1/cts?d=79-293-2-3-10648-36175-1...

    what is the difference between 74ls and 74hc

    difference between hc and vhc One point that was implied, but maybe not stated. HC has the same functions as the corresponding TTL part, but the parameters are different. i.e. they are not interchangeable in a actual cicuit! The HCT line was introduced to be closer fit and can be...

    Detecting which radio stations people listen to?

    I recently saw an article about a "smart" billboard which detected which radio stations passing cars were tuned to and adjust it mesage for the precieved target group. Any ideas on how this is done? The coupling between the station and the reciever has to be of a low order, the changes in...
