 		 #146876 - P89V51RD2 system
Responding to: ???'s previous message
Yashveer Singh: Can you suggest me some controller to start with which would be readily available and not very costly. Also what downlaoder can i use for .ihx file generated for the controller you would suggest?


In the links below there is a simple system I designed and used often both assembled in a bread and in PCB form. It uses the P89V51RD2 microcontroller from NXP. It is cheap, easy to assemble, easy to program, and easy to flash.

Schematic:

Breadboarded system:

It should take under an hour to setup this system with nice-short wires as shown in the picture. All the parts were acquired from DigiKey. If I remember correctly the parts for this system, not including the breadboard, cost around 9$ (Canadian).

The compiler I use is SDCC (http://sdcc.sourceforge.net/). I also put together a simple IDE which includes a flashing utility for the P89V51RD2 microcontroller. You can download it from the link below (use at your own risk):

http://www.ece.ubc.ca/~jesusc/crosside_setup.exe

Aditionally, I have been told that this simple Window$ flashing program I wrote for the P89V51RD2 runs on Linux under Wine (use at your own risk). Both the source code and the executable are included in the zip file.

(This microcontroller system also works fine with Flashmagic.)

For debugging, I put together CMON51 some time ago. CMON51 is a monitor for the P89V51RD2 you can download from:

http://cmon51.sourceforge.net/

Well, that is all. Hope this helps...

               Please explain one by one what you need to do.            01/01/70 00:00      
               this way            01/01/70 00:00      
                  you got it!!!            01/01/70 00:00      
                     dont forget the Boot Loader part of the job            01/01/70 00:00      
                        what bootloader "part of the job"            01/01/70 00:00      
                           there is nothing to do there - here-            01/01/70 00:00      
                              he does NOT need to make a "Boot Loader"            01/01/70 00:00

                           or it can be this way            01/01/70 00:00

   I do not know what you imply by "low cost"            01/01/70 00:00      
      for "home" and hobby use, though...            01/01/70 00:00      
         WHY?            01/01/70 00:00      
            hobby...            01/01/70 00:00      
               I doubt that            01/01/70 00:00      
                  OK, then maybe 95.3%            01/01/70 00:00      
                     but let's talk about the rest            01/01/70 00:00      
                     We once had a selection of shops ...            01/01/70 00:00      
      $99 is no low cost            01/01/70 00:00      
         low cost is a relative term            01/01/70 00:00      
            Everything in this world is relative            01/01/70 00:00      
               many hobbyist use SILabs devboards            01/01/70 00:00      
                  many hobbyist use SILabs devboards            01/01/70 00:00      
                     check with Mouser            01/01/70 00:00      
                        or Digi-Key            01/01/70 00:00      
                           DigiKey doesn't seem to stock 'em            01/01/70 00:00      
                           @#$%! double post! sorry            01/01/70 00:00

                  It's not rocket science            01/01/70 00:00      
                     what about the cost            01/01/70 00:00      
                        that can vary widely            01/01/70 00:00      
                           which?            01/01/70 00:00      
                              look at the available peripherals            01/01/70 00:00      
                                 last you raised this issue            01/01/70 00:00      
                                    that\'s only half the story            01/01/70 00:00      
                                       The connector on the SiLabs boards is female            01/01/70 00:00      
                                          to some people, that's ambiguous            01/01/70 00:00      
                                             Stop yapping and start reading!            01/01/70 00:00      
                                                When I ask the question ...            01/01/70 00:00      
                                       Why do you even care            01/01/70 00:00      
                                          I care because it has to work.            01/01/70 00:00      
                                             I knew I had one laying around            01/01/70 00:00      
                                                That is not how I see it            01/01/70 00:00
