How on earth do I get PBP3 to talk to my EasyPIC v7 ?

EasyPIC v7 USB device drivers are loaded and running. Windows 7 (64Bit) can see the board.

PBP3 is running but when I try to unite the two I get nothing.

[HenrikOlsson]

Hi Andy,
I have tried to explain this to you in one of the other threads but I guess (yet) a new thread is better than continuing in one of the others. Anyway....

You need to understand that PBP is a compiler, it compiles programs - that's it. It does not talk to ANY hardware what so ever.

You use PBP to compile programs, the compiler than automatically launches the assembler (that's why you need MBLAB installed) and the outcome of the assembly process is a .hex file which is to be programmed into the PIC chip (can be one on the EasyPIC 7 or elsewhere, PBP does NOT know or care).

If you want to program the PIC chip onboard the EasyPIC7 you need to use the programmer application supplied with the board (mikroProgSuite).

For future reference, are you using PBP3 as a tool inside MPLAB or are you using the MicroCodeStudio IDE or are you using anything else?

Finally, I'm sure you realise that PBP3 is a product from MicroEngineeringLabs while the EasyPIC 7 is a product from one of their competitors (MikroElectronica).

/Henrik.

[AndyFreestone]

This is the problem. PBP3 just does not connect to IDE ???

PBP3 outputs .pbp files. How the **** do you then import them into IDE.

You state that PBP launches IDE - HOW ??

I've tried asking melabs, but they are about as helpful as a chocolate fireguard to us newbies.

I appreciate that these are simple questions to seasoned PIC programmers but us newbies need somewhere to start.

I don't mean to be a pain but it's often difficult to ask the right question in the right topic.

Does anyone know of a good tutorial just to exercise how the bits are supposed to work together.

Once I can get a simple program into a PIC I can then progress.

Most tutorials stop short. Yes they show you the basic programming, and then they jump to IDE. Can someone come up with a single tutorial that lights an LED ?

I'm perfectly capable of writing PIC basic but I just cannot understand the process of getting it into the PIC.

As Henrik explained (several times actually):

You need to understand that PBP is a compiler, it compiles programs - that's it. It does not talk to ANY hardware what so ever.

You use PBP to compile programs, the compiler than automatically launches the assembler (that's why you need MBLAB installed) and the outcome of the assembly process is a .hex file which is to be programmed into the PIC chip (can be one on the EasyPIC 7 or elsewhere, PBP does NOT know or care).

If you want to program the PIC chip onboard the EasyPIC7 you need to use the programmer application supplied with the board (mikroProgSuite).

[HenrikOlsson]

Hi Andy,

This is the problem. PBP3 just does not connect to IDE ???

IDE stands for Integrated Development Environment. It's piece of software on the PC, basically a fancy text editor with some extra functions. MBLAB is an IDE and MicroCodeStudio is an IDE.
The most common one for use with PBP is called MicroCodeStudio.

PBP3 outputs .pbp files. How the **** do you then import them into IDE.

No. If you're using MicroCodeStudio it saves your source files as .pbp files but these are just plain text file. Before you can get them into the PIC you need to compile it/them. This is where PBP3 comes in.

Question: Are you, or are you not using MicroCodeStudio as the software in which you write your PBP programs? If not, what are you using?
Before we've got that squared away it's hard to give proper advice because you can very well write your program in notepad and compile them from the command line.

You state that PBP launches IDE - HOW ??

I did NOT state the PBP launces IDE. I said that PBP launches the assembler automatically (as long as it's installed properly).
PBP3 can be launched FROM the IDE but not the other way around, but again, before we know what IDE you're using it's hard to help.

At the top of the window of the program you're using to enter your program, what does it say there?

/Henrik.

[AndyFreestone]

HOW.

I am using MicroCodeSudio. It does not automatically launch IDE.

All I get is .pbp files as previously explained.

The the top of the window it says MicroCodeStudio - PICBASIC PRO

I can press the compile button but where does the .hex file go.

[rmteo]

Yet another hapless response - HOW.

I am using MicroCodeSudio. It does not automatically launch IDE.

All yours, Henrik. Have fun!!!

[HenrikOlsson]

I am using MicroCodeSudio. It does not automatically launch IDE.

Finally, we're getting somewhere..... First of all MicroCodeStudio IS the IDE.

Select View->Compile and program options and make sure the correct path where PBP3 is installed is specified there. If not, click Find Automatically and let it search for it.

Then Click the Compile in the toolbar. (The IDE (MicroCodeStudio) will now launch the compiler (PBP3) which will compile the program and the launch the assembler which will assemble the compiled program into a .hex file. That file will be in the same folder as you saved your source file/program. It's that .hex file you should program into the PIC.

If you don't see the compile button click View->Toolbars and check and make sure that Compile and Program is enabled, the button should now appear.

/Henrik.

EDIT: I guess you've seen the install video that's on the MELABS site? If not, here it is.

[Demon]

Tell microcode studio where pbp compiler and mpasm resides.

Type in your program, then click compile, then start whatever programming software came with your development board.

That software will use the hex file from compile to program your pic.

Robert

[AndyFreestone]

OK - sorry to sound rude but it's just so frustrating when there isn't a simple tutorial to follow.

I've managed to get mikroProg suite for PIC to load .hex files onto the EasyPic v7 so I'm halfway there.

I simply cannot get PBP3 to generate .hex files, all it generates are .pbp files ?

[HenrikOlsson]

Hi,
I understand it's frustrating but you're not helping us help you either. It'll be much easier to help you if describe in more details what you're doing so we can spot any possible mistakes that you may be doing. Simply saying that it doesn't work is the worst problem description ever - which I'm sure you, as an engineer, can appreciate. We've tried to explain the process in quite some detail here but apparently we've either haven't been clear enough or you're not following the instructions properly or there's something wrong preventing it from working.

* Did you watch the video I linked to?
* What does it say when click View->Compile and program options, does it point to the folder where you indeed have PBP3 installed?
* What happens when click the Compile button in MicroCodeStudio? Any error messages? If so, what does it say?

/Henrik.

[AndyFreestone]

Finally I'm getting somewhere.

My apologies but I eventually found the .hex files that PBP3 has been generating.

I'm starting with the real basics - trying to turn on an LED.

I can't get any of the demo projects to work at all !! I did read and save the hex from the demo board and can reload that successfully.

[HenrikOlsson]

And where did you find it?
Again, saying that it doesn't work doesn't allow us to help you. Can you compile them? Did you select the correct target device and which one is that?

I'm perfectly capable of writing PIC basic but I just cannot understand the process of getting it into the PIC.

There are a lot of jumpers/switches on the EasyPIC7 board that needs setting correct for whatever to work.
A simple blink-a-led is by far the best method to verify that the PIC is actually running. If you feel, despite the above, that there MIGHT be something wrong with your code then post it - all of it.

[AndyFreestone]

I've just been playing with the examples that came with the demo version of MikroBasic Pro. I've had to play with the jumpers to get some of them to work too.

I'll have another try with PBP3 Pro as I do find the PBP basic far more intuitive.

PBP3 doesn't appear to need the CONFIG data that I am expecting ??

Is that generated automatically ??

The PIC on the board is an 18F452 - probably far more complex than I need, but hey, I've got a boxfull of them.

The ICD is set for the correct processor, the correct clock speed (4MHz) and the rest are at defaults.

All I'm attempting at this early stage is to set trisc to 00000000 and then set one pin high to illuminate an LED - hardly rocket science.

[HenrikOlsson]

Hi,
PBP has default set of CONFIG settings for each individual device which it uses if you don't "override" via the #CONFIG/#ENDCONFIG directives (see the manual for details). To find out what default CONFIGs PBP is using for the particular device go to your PBP3 installation folder, open the DEVICE_REFERENCE folder and open the .info file for your particular device - everything is described there (they are plain text files).

When compiling make sure you use the Compile button (or F9), don't use the ICD Compile.

/Henrik.

[AndyFreestone]

Just to try something, I was playing with a working example.

By changing the values written to Port B I would have expected the LED pattern to change. It didn't is stayed exactly the same.

Even when I removed all the calls to write to all the ports they kept on flashing as per the original program.

Do I have to delete the old .hex file and then recompile? I would have expected a recompile to overwrite a previous version ?

[Demon]

You really should bring this up on a forum that supports your programmer.

[Acetronics2]

Hi, Andy

playing it simple ...

I 'm working for years with an Easypic 5 ... Ok ???


1) you need to have the " Mikroprog suite for pic " and its drivers ( on your EasyPic CD or Here http://www.mikroe.com/easypic/programming/ ) installed.

2) connect your Easypic with the USB cable to your computer. power ON

3) open the mikroprog suite and @ first choose processor family and processor reference
Then hit : File/Load Hex in the upper left menu ... and browse for the PbP Hex generated file you want to program.

it's Here for me : C:\Documents and Settings\Alain\MCS_Prog ... Yes, Alain is my name !

4) Hit the " code" Button to show your Hex in the appearing window ...

5) Hit the " WRITE" button just under the processor reference ...

it runs ...

Alain

Edit ...

AND ...YES ... Easypic can be directly driven from MCS ...
just browse this forum to find the " How to " ...

[HenrikOlsson]

Andy,
Are you sure that you're actually ARE reprogramming the chip? It doesn't sound like you are to me.
Of course you MUST recompile the program and of course you MUST reprogram the chip - how else would it work? When you recompile the .hex file on disc will be replaces with the newly compiled (no need to delete it) but the one in the chip will of course only be replaced when you reprogram the chip. The above is how PBP and MicroCodeStudio does it. If you're actually working with the MikroE examples and their compiler then I don't know and you'll be better off asking the question on the MikroE forum.

Normally the programmer automatically erases the chip before programming but I'm sure there are settings for that in the programmer software.
If you load a .hex file into your programmer software you can use the VERIFY function in the software to compare that .hex file to the one currently in the chip. If they are not the same then you haven't reprogrammed the chip properly.

Robert,
Come on, give the guy a break will you, he's new at this and apparently struggling quite a bit (more than anyone in a long time for some reason).

/Henrik.

[AndyFreestone]

Too right I'm struggling.

The board is going through the motions of erasing and rewriting to the PIC.

Could someone send me a .pbp or plain text basic listing for say the 12F509 in PBP3 just to see where I am going wrong.

the manual just doesn't seem to have any tutorials and the example programs just don't work.

All I want to do is to set TRISA to 000000 and then to POKE and output to it to see an LED illuminate. Everything that I have tried so far has come up with a syntax error - including the examples that come with the program.

The manuals seem to be written by experts for experts. I'm an old man trying to learn new tricks.

[AndyFreestone]

This is an example that just does not work - OK laugh but once I get through the basics I'll be playing all night.

Doesn't compile due to your wrong CONFIG ...

so; moreover, it can't be programmed into the chip ...

Sorry but that might as well be in Japanese to me.

[HenrikOlsson]

Hi,
The PIC12F509 doesn't have a PortA and therefor no TRISA or PortA registers, so you get an error when you try to access things which are not available.

OK - how should it read ?

I'm trying a real basic 12F509 to start with but for convenience I also have 12F629, 16F684, 16F506, 16F722 and loads of 18F45K22's

[AndyFreestone]

Thanks Henrik,

How does PBP3 address the single port of the 12F509?

Andy

I, probably wrongly, assumed that it would use TRISA.

I did try to edit the sample program for the 18F452 just to change the outputs but nothing changed. We'll leave that problem again until later.

[HenrikOlsson]

As it does with any other register - by the registers name, which on the 12F509 is either PortB or GPIO for the actual port and TRISB or TRISGPIO for the "direction".
You know, assumption is the mother of all f**k-ups so never assume anything - a simple look at the datasheet for the device would have told you that there is no PortA.

Didn't I say the same thing? lol

All he needs is to get one example working right on whatever chip he decides to use. He's got at least 2 to work with now, so it's down to hardware connection/setup, or programmer software.

[AndyFreestone]

As it does with any other register - by the registers name, which on the 12F509 is either PortB or GPIO for the actual port and TRISB or TRISGPIO for the "direction".
You know, assumption is the mother of all f**k-ups so never assume anything - a simple look at the datasheet for the device would have told you that there is no PortA.

/Henrik.

Again way over my current knowledge. How do I address THE PORT in PBP3 ?

[HenrikOlsson]

Like I said, on the 12F509 THE PORT is named PortB or GPIO not PortA.
Otherwise you had it right - HIGH PortB.0 or HIGH GPIO.0 instead of HIGH PortA.0

EDIT: I'm sorry, make that GPIO.0 only, PortB was for the 12F605 only which share the same datasheet.

[AndyFreestone]

OK I've now got a HEX file that has compiled correctly. PBP3 does not recognise the EasyPIC board and the other IDE programs are looking for PICs that are far more advanced than my poor peasant. How do I now get that HEX file into a poor mariner. I've also got 10F200's that I would like to play with.

[AndyFreestone]

MikroProg Suite for PIC came the closest. It could program the PIC 12F509 but came up with over 1000 errors with the compiled code.

Maybe the PIC 12F509 just has so little memory that it can't cope with compiled code ??

Gooligum comes up with some useful assembly code programs, how do I implement assembly code into PBP3 ?

I'd rather just work the PBP3 basic - Believe it or not I am quite proficient in BASIC programming.

[HenrikOlsson]

Geez, we've been thru this a couple of times already.....
You open/load the .hex file into the programer software (mikroProgSuite). That software then connectes to the hardware device programmer which is on the EasyPIC7 board and you use it to "download" the .hex file into the PIC.
I'm sure there's a manual or help file available for the that software if you need it.

If you haven't had the 12F509 running on the EasyPIC7 board make sure to read the manual (for the board) on how to set the board up for that device.

/Henrik.

[mackrackit]

PBP3 does not recognise the EasyPIC board

Of course it does not, PBP is a compiler.
PBP takes text written in BASIC syntax and turns that text into text written in ASM syntax. Then MPASM is used to make a HEX file from the ASM text. It is up to YOU to pick the programmer (device) to transfer the HEX file to the chip.

Hi, Dave

Have a look to post #1 ... it's not a Pickit but an EasyPic board ...

you still don't wear your programming glasses ??? .... ohhhhhhh ... what a bad guy !

Regards
Alain

[mackrackit]

Yes, I know the OP is not using a PicKit. I was hoping the OP might get a general understanding of how programming works by reading through Steve's tutorial. With any luck, once he understands how code is created and moved to a processor he will be able to figure out how to use the tools he has.

But I am thinking of getting a pair of tri-focals... ;-)

[AndyFreestone]

The manual for the board is pretty basic. As far I can ascertain the board is correctly set.
