    Default DT_INTS and 18F26k22

    Hi all, I am using PIC 18F26K22 and INCLUDE "DT_INTS-18.bas"

    I get error: Symbol not previously defined (INT_ENTRY_H)

    Any clues?

    Thanks

    Any clues?
    any hints like :-


    pbp ver = ?
    dt_ints ver= ?
    interrupt your trying to create = ?
    code ?


    or do we have to guess ?

    Terribly Sorry Richard, though it might be a fuse setting

    PBP ver = 2.60A
    DT_INTS ver = 3.3

    So far I have just a debug statement and a high/ low/ pause on PORTB.2
    I added the Include and it threw the error

    if you don't create at least one valid interrupt no interrupt handler is created
    hence
    Symbol not previously defined (INT_ENTRY_H) error occurs

    the dt_ints include has nothing to work with and just can't cope

    I have had some issues with the different versions of PBP so I upgraded to Vs PBPX 3.1.0.4

    This program compiles just fine but it does not enter the interrupt on RX
    Code:
        INCLUDE "modedefs.bas"
        include "ALLDIGITAL.pbp"
        INCLUDE "C:\PBP\DT_INTS-18.bas"     ; Base Interrupt System
        INCLUDE "C:\PBP\ReEnterPBP-18.bas"     ; Include if using PBP interrupts
           
        Define PULSIN_MAX 1000
        DEFINE HSER_RCSTA 90h   'Hser receive status init
        DEFINE HSER_TXSTA 24h   'Hser transmit status init
        DEFINE HSER_BAUD 9600  'Hser baud rate
        DEFINE HSER_SPBRG 25
        DEFINE HSER_CLROERR 1 
        DEFINE OSC 4
        OSCCON =$D2 'clock speed
         mem1 var byte  
    
    ASM
    INT_LIST  macro    ; IntSource,        Label,     Type, ResetFlag?
            INT_Handler    RX1_INT,    _read_serial,   PBP,  yes
            
    
       endm
        INT_CREATE             ; Creates the interrupt processor
    ENDASM   
    
    @  INT_ENABLE   RX1_INT     ; enable external (RX) interrupts 
    
       
     MAIN:
     
     SEROUT2 PORTB.0 ,16468,["here",cr,cr]
    
     pause 500
    GOTO MAIN  
     
     read_serial:
     hserin 250 , NoRS232,[mem1,mem1]
     
     serout2 PORTB.0,16468,["got it",cr]
     Pause 1000
    
    @ INT_RETURN 
    
    NoRS232:
    
    serout2 PORTB.0,16468,["No rs232",cr]
    
    @  INT_RETURN
    The exact same code runs in the 18F1320 except the OSCCON is $60 for the 18F1320 and $D2 for the 18F26K22.

    Does anyone know where I might be needing to look?

    A few things I learned about the DT_INT routines is:

    1 - You must have a copy of the DT_INT and ReEnterPBP code in the file where you save your current program. PBP3 will not search the computer and create a path. Thus, I have multiple copies of the code on my computer.

    2 - It is helpful to open the DT_INT in PBP3 and look at how the "RX1_INT" is structured in the code, and where it is looking for PIE, PIR, etc. The K22 family is relatively new, and as you stated, OSCCON SFR is structured differently than for older chips. You may have to alter the DT_INT itself, or alter the way you INT_LIST your IntSource.

    3 - At the top of the DT_INT (I believe for the PIC12F/16F) there are multiple wsave options that you have to comment out or uncomment, depending. I don't remember the -18 requiring that, but I may be wrong. On the lower chips, you must include one of the wsave options in your variable declarations of your main code (wsave VAR BYTE $20 SYSTEM for example).

    I'd wager a guess the issue you're having is #1, your interrupt routines are not in the folder you're saving your current program.

    mpgmike, I have been using DT_INTS-18 for quite a while with 18F26K22 parts as soon as Microchip released them. It's been a few years now. I have never had to change anything to do with Darrels code. What are you talking about?

    FYI: You can specify a relative path. I have a separate folder for all my includes. It is located in the same root folder of all my projects:


    Code:
    C:\
         ---Somewhere
               ---MyPBPProjects
                    ---MyIncludes
                    ---Project1
                    ---Project2
                    ---Project3
    Here my include folder is named _Include
    Code:
    INCLUDE  "..\_Include\DT_INTS-18\DT_INTS-18.bas"   ' Base Interrupt System
    INCLUDE  "..\_Include\DT_INTS-18\ReEnterPBP-18.bas"   ' Include if using PBP interrupts
    
    ...
    
    INCLUDE "..\_Include\DT_INTS-14_V110\DT_INTS-14.bas"   ' Base Interrupt System
    INCLUDE "..\_Include\DT_INTS-14_V110\ReEnterPBP.bas"   ' Include if using PBP interrupts
    
    ...
    
    INCLUDE "..\_Include\ESP8266_Base.pbp"
    INCLUDE "..\_Include\NMEA_base.pbp"
    'etc

    Dave, are you using DT_INTS for RX1/RX2 interrupts? If so, how?

    Thanks Dave, no matter what I try on the 18F26K22 it will not jump to the interrupt. I'm ordering some different chips with 2 UARTS to give them a try.

    Bingo!

    Thanks Richard, this line
    Code:
    anselc = 0 '0 = Digital input buffer enabled
    did it!
