Got my p16Pro - Electronic Circuits Projects Diagrams Free

Squintz · 17th October 2003, 03:56 PM

I got my programmer and its fully assembled. And i went to the store and baught the parts to connect it to my variable power supply and i got some solder type protoboards. Now all i need is for micro to deliver my sample pics i ordered last wednesday.

About how long did it take for you guys to receiver your free samples?

Also i notice that the pic programer uses a DC plug but it says it accepts ac and dc. What is the polarity of the DC? is it Positive or negative center?

took about 2 weeks for me...

but this is belgium... once it reaches the postal offices here things get really slow :lol:

Squintz · 23rd October 2003, 07:02 PM

OK i got the PIC16pro and i got my PIC16f84a i built a circuit shown here:
http://www.mstracey.btinternet.co.uk.../progtut12.htm

Now i want to take the code from that site and program my PIC

What software do i need? Please give free ones and links are good!

Squintz · 23rd October 2003, 07:19 PM

Well while waiting from a responce from you guys i ound PicALLw software but still i dont know what to do with it. How do i take the program from the above site and get it into my PIC.

Kane2oo2 · 23rd October 2003, 07:43 PM

you need a program which turns that assembler code into a hex format which can be programmed into the chip.

the most well known is MPLAB which can be found at the microchip webiste and is free

OK i got MPLab and installed it. How do i use it?

Open your files in a project. Then at a node. Then tell wich PIC you have and then you BUILD ALL. And then you see in your work space a HEX.

It does not matter. The plug connects to the rectifier bridge, so whichever plug configuration you use the programmer will still work.

the picallw software was written by the guy that designed the programmer. His software is not free, if you want to use a PIC other than the F84 you'll have to register your software. A free programmer that works with the p16pro is icprog. The settings to make the software work with your programmer are here.

ok... Got the IC-Prog and installed it. And i have the following code.

now do i put that code into an text file and save it as "FILE.asm" and then goto open file? When i do that it ask me if i want to swap bits.

Can someone please explain what i do once im in the program. I have already setup the prog as the link above said to. and i'v picked that im going to be programming a pic16f84a. Whats the next few steps? When i first chose my PIC that i was going to be programming the window filled up with all kinds of HEX? What is all that Hex code for. Do i delete this hex?

Exo · 24th October 2003, 07:10 PM

First go to MPLAB IDE

Choose 'Project' - 'New' to create a new project
give it a name and a destination folder

Then choose 'project' - 'add files to project' and add your file.asm to the project

then choose 'project' - 'build all' to compile your file (turn it into machine code HEX file)

The now produced hex file (if you have no errors) is the one you need to open with ICPROG

Why all the errors.... I got this code right from a web site and tryed to convert it into hex with MPLab and no luck!

Exo · 24th October 2003, 11:03 PM

They're warnings, not errors (the build succeeded, see the last line)

Microchips assembler persists that you nicely format your file...
Put labels at the beginning of a line, and code after some tabs, and so on

like this

Code:

    ORG 0x00
    goto main 

Main
    org 0x04 
    movwf TEMP 
    incf COUNT,1 
    ...
    ...
    End

It is meant to make your code more readable and easyer to understand
... You got to admit, the code you posted looks like quite a mess without format

Bank selection messages, you'll get them all the time, even when code is correct..

ignore them or add ERRORLEVEL -302 to the top of your code
