Proteus ISIS custom PIC's

[TheKnight]

Hi to all.

I've noticed that in Proteus there isn't a plain PIC16F84, only the 16F84A. Following the attached schematic, I noticed it's done with 16F84. What would the difference be? Will the other PIC be a problem? Should the pins be switched?

The schematic is taken from : http://www.ke4nyv.com/picprojects.htm

If someone happens to have projects done in Proteus or other simulation programs, feel free to share.

Thanks to all, happy holidays and a happy new year!

The 'a' version is just a later silicon revision, and both are LONG obselete, they were replaced by the 16F628 way back last century!.

So I should definetily consider other PIC? Or maybe Arduino? I was checking out Arduino, seems pretty decent but it's not as famous as the PIC or am I wrong?

Go on Nigel..... I'm waiting for the aaarrrggghhh!!!....." Arduino is a platform not a micro " speech...

"Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software." My bad.

Arduino is originally for the AVR chips now its on a ton of others from ARM-FPGA-PIC etc.. Arduino is great for beginners... if you are a beginner then use it, i hear its awesome .. i use everything

Arduino for AVR and FPGA
Xilinx ISE for FPGA
MPLAB X for PIC
Crossstudio for ARM

so it up to you to choose what direction to take... PICs are more common here but AVR is picking up speed (slowly)

Arduino for AVR and FPGA

Surely the FPGA shields need a JTAG cable or is the AVR capable of programming it?

Nope i use this:

Really fun and easy as pie! Can also use this on it:

its 100Mhz softcore... real simple and also open source... can run sketches from arduino software (modified version)

All of the above using a FTDI USB type setup so no real JTAG 20pin is needed... nice and simple

If your upgrade licence has expired, u can obtain the new library and model files by downloading and installing the latest demo on another pc. Then just copy them across to your active installation.
