    Default PBP for dsPIC 16bit??

    hi all,

    Is it possible??i mean all the command listed in the PBP green book can be used for dsPIC??

    thanks

    Short answer: No.
    PBP works with PIC10, 12, 16 and 18 "only".
    I'd probably take a look at MikroElectronikas mikroBASIC PRO for dsPIC or move over to the dark side....

    Hi,

    The subject was discussed some times ago ...

    looked Melabs had no real project for 16 bits ...

    May be Charles Leo could make a little " update " about the future ...

    BTW CCS C compiler also is a possibility ( take care to recent versions > 4.110 : somewhat buggy ...)

    And why would 16-bit PICs be interesting? A PIC16 is rated at 5MIPs and the fastest PIC18s are rated 16MIPs (typically 10MIPs). The 16-bit PIC24/dsPIC are rated from 16-40MIPs. However, MIPs (million-instructions/second) are very misleading and do not not take into account things like instruction and data sizes. So how, for example, does a 10MIPs PIC18F97J60 compare to a 16MIPs PIC24FJ64GA004 - is the PIC24FJ 1.6x faster? In real world testing and benchmarking, it is more like 13-23x. Comparing PIC32s which are rated at 40-80MIPs, the disparity gets even larger. Instead of 4-8x that of a PIC18, it can be as much 160x. Take a look at the CoreMark figures (last column) in the table below.

    hi,
    any example of application using dsPIC??
    if it is just driving specific motor application would be wasted for dsPIC??

    thanks

    Exclamation PBP for dsPIC 16bit, why not?

    Why not? I've never used or seen a DSpic but thought this an interesting subject so I did some googling:

    dsPIC30 is a 16bit mcu:
    http://ww1.microchip.com/downloads/e...Doc/70102K.pdf
    (p. 62)
    The format supported is the Intel® HEX 32 Format (INHX32).
    PIC 24F are also 16bit mcu:
    http://ww1.microchip.com/downloads/e...tes/91025a.pdf
    (p. 2)
    The formats supported are the Intel HEX Format (INHX8M), Intel Split HEX Format (INHX8S), and the Intel HEX 32 Format (INHX32).

    It would seem it's just a matter of using a programmer that generates INHX32 hex files. I have no clue which format is generated by my MeLabs U2 programmer. The most I could find was:

    The melabs programmer software is compatible with the standard Microchip HEX format files.
    INHX8M? INHX8S? INHX32?


    So, is it possible that finding a programmer that generates INHX32 hex files is the only hurdle to using PIC Basic Pro on dsPIC devices?


    Or am I totally not seeing something?



    EDIT: This is from 18F2550.INC in PBP folder:

    LIST p = 18F2550, r = dec, w = -311, w = -230, f = inhx32
    So a PIC 18F2550 is apparently programmed in INHX32 format, why couldn't a dsPIC?

    I wouldn't make a statement like that (EDIT: Until Microchip closes the production line or issues a formal statement).

    http://www.microchip.com/en_US/family/16bit/index.html

    Microchip’s 16-bit, PIC24 MCUs and dsPIC® Digital Signal Controllers provide designers with an easy upgrade path from 8-bit PIC® microcontrollers and a cost effective option to 32-bit MCUs. The broad product line includes everything from eXtreme Low Power microcontrollers to high performance digital signal controllers. Combined with hardware and free software these 16-bit products make the design of Control, mTouch™ Sensing, Graphics, Connectivity, Digital Power Conversion, Smart Sensing and Motor Control solutions easy to implement.

    Simple answer - no. Programmers do not generate INHX32 files - that is the job of the compiler. The files required by a PIC12/16/18 is very different from that of a dsPIC. While it may be possible to take a
    PIC12/16/18 HEX file and burn it into a dsPIC, it will not do what you expect it to.

    Ok, my mistake.

    If this is from 18F2550.INC in the PBP folder:

    ...
    Then it will be used by compiler right?
    (Mecanique Studio Plus, MPLAB or whatever alternatives if there are any)

    So, wouldn't you still end up with an INHX32 hex file anyways?

    Question Re: PBP for dsPIC 16bit??

    (just had a thought)

    Or is it more an issue of how the commands are structured within the hex file?

    The layout is compatible, but the commands are not.

    That is the "file format" same as pdf, doc,pbp,xls,dwg and so on.

    But the content will not be correct. At best you will get an eight bit program to run on a 16 or 32 bit processor. This will not be too good. For instance, when we declare a WORD variable, the compiler generates code to make the uP act on the WORD in multiple BYTES. The 16 bit uP would not need the extra overhead of manuiplating the BYTES since it can handle WORDS. But the program would have it anyway since it was compiled for an eight bit uP.

    PBP could very well have a separate compiler switch like it does for longs to switch up to 16 bit compiler, yeah it would probably be a a complete rewrite from the code in an 8 bit compiler but the interface could remain the same and use the same syntax. Look at how similar "C" compilers are for each series. All said I think it would be Do able, however; I think the upgrade price would be steep, I think it would HAVE to be. My thoughts are it would be worth it so as not to need retraining in " C ".

    You can start right now with assembler or C... it's free (with some limitations).

    If you already mess with 10,16,18 series, then you'll discover PIC24, DsPIC, PIC32 assembler is far different... not to mention the extra features and architecture.

    Download a datasheet... then oh surprise, you also need to download the family common datasheet for x specific section of the internal peripherals.

    Yes it is a complete rewrite, no it's not simple... and no you don't need to stick to C, there's already Basic compilers available.

    On the long run, you may find it handy to know C.

    If you want to leverage your efforts into commercial/professional activities, then C/C++ is the way to go. It dominates the market at 84% (ASM is the next highest with 5%) with all other languages making up the balance of 11% - BASIC (all dialects, not just PBP) accounts for 1% of total usage.

    It's been said countless time in here, compilers are just tools. You want to have more than one screwdriver in your kit.

    I say, if you can, learn them all

    And Proton seems to make the first steps in the 16bit world just the previous few months. But looks more promissing than Mikroe with the tons of bugs.

    Well, I wish too for the step forward, but on a stable compiles. And Charles I am sure will do this when he is ready. I feel that the time comes...

    yes i have looked at mikrobasic perhaps for the arm processors , not look at the bugs that may come with it as yet

    i also cant see why microchip cant put larger amount of ram/prom in 18f products , would be great for say 256k/ 384k option , but that reserved for 16/32bit devices

    You answered your self.

    So, it seems that we have the freedom to "choose" which PIC to use. I say, they make us to choose the bigger chips for more memory.

    @ Robert,

    The text you select had been written in 2011... not sure that 18F67J94, if exist at this time, was suported by PBP2.60...
    ;-)


    I can see now, that, here in France, electronicians are using more and more ARDUINO, raspberry Pi, beaglebone.... (linux embedded and python prog) May be because of the price and no simple basic compiler for big PIC available. (?)

    Hi,
    The 18F67J94 (or, in fact, any of the xxJ94 devices) doesn't seem to be supported even by PBP3 (Supported devices).
    I'd love for PBP to support other device families but as have be said, the 24 and 32 series PICs are completely different animals compared to the 12, 16 and 18 series. However, and I know the thread is old so the point may be moot but if 4 USARTs is the driving factor for going to a 32bit microcontroller one might think about taking a step back and re-evalutate. Take a look at the MAX3107 for example, 4UARTs with 128bytes FIFO buffers, SPI/I2C interface to the main controller.

    /Henrik.

    Hi,

    I used some PIC24 with Basic and it's different from 12,16,18 series, but easier than using a new device like MAX3107.
    For MAX3107, it seems that it is a new device (2014 ?) and I remember that I found some other same kind of device in 2011. They were very expensive !

    This topic is not mine and there are many other things than 4 USART to use with 24 and 32 series.
    There is a song here that says those who do not go forward, go backward.
    I hope it's not already too late ;-)
