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

Mike

Any clues?

any hints like :-

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

or do we have to guess ?

Re: DT_INTS and 18F26k22

Terribly Sorry Richard, though it might be a fuse setting :confused:

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

Re: DT_INTS and 18F26k22

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

Re: DT_INTS and 18F26k22

Thank you for cluing me in :D

Re: DT_INTS and 18F26k22

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?

Re: DT_INTS and 18F26k22

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.

Re: DT_INTS and 18F26k22

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

Re: DT_INTS and 18F26k22

Michel, That is exactly the way I have been doing mine for years....

Re: DT_INTS and 18F26k22

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

Mike, Here are some snipits from a program I wrote about 4 years ago:

Re: DT_INTS and 18F26k22

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.

Re: DT_INTS and 18F26k22

this works for me

Code:

#CONFIG CONFIG FOSC = INTIO67 CONFIG PLLCFG = OFF CONFIG PRICLKEN = OFF CONFIG FCMEN = OFF CONFIG IESO = OFF CONFIG PWRTEN = OFF CONFIG BOREN = SBORDIS CONFIG BORV = 190 CONFIG WDTEN = ON CONFIG WDTPS = 32768 CONFIG CCP2MX = PORTC1 CONFIG PBADEN = OFF CONFIG CCP3MX = PORTB5 CONFIG HFOFST = ON CONFIG T3CMX = PORTC0 CONFIG P2BMX = PORTB5 CONFIG MCLRE = EXTMCLR CONFIG STVREN = ON CONFIG LVP = OFF CONFIG XINST = OFF CONFIG DEBUG = OFF CONFIG CP0 = OFF CONFIG CP1 = OFF CONFIG CP2 = OFF CONFIG CP3 = OFF CONFIG CPB = OFF CONFIG CPD = OFF CONFIG WRT0 = OFF CONFIG WRT1 = OFF CONFIG WRT2 = OFF CONFIG WRT3 = OFF CONFIG WRTC = OFF CONFIG WRTB = OFF CONFIG WRTD = OFF CONFIG EBTR0 = OFF CONFIG EBTR1 = OFF CONFIG EBTR2 = OFF CONFIG EBTR3 = OFF CONFIG EBTRB = OFF #ENDCONFIG ;INCLUDE "modedefs.bas" ;INCLUDE"ALLDIGITAL.pbp" ;INCLUDE "HomeAutomationVars.bas" 'Open with PBP editor INCLUDE "DT_INTS-18.bas" ; Base Interrupt System INCLUDE "ReEnterPBP-18.bas" ; Include if using PBP interrupts define OSC 8 DEFINE DEBUG_REG PORTB DEFINE DEBUG_BIT 7 DEFINE DEBUG_BAUD 9600 ' Set Debug mode: 0 = true, 1 = inverted DEFINE DEBUG_MODE 0 x var word rxflag var bit rxchar var byte ASM INT_LIST macro ; IntSource, Label, Type, ResetFlag?

this is much better , get rid of all those nasty pauses and goto's

Re: DT_INTS and 18F26k22

Bingo!

Thanks Richard, this line

Code:

anselc = 0 '0 = Digital input buffer enabled

did it!
