How to resolve assembler error 306?
I am trying to convert some code I have used very succesfully in a 18F2550 to a 16F886. When I attempt to compile the code for the 16F886 with PBP v2.6/MSASM I get an assembler error while using the FineLine Editor that says it is a FL unrecognizable error. The error is "Message [306]: Crossing page boundary -- ensure page bits are set". I googled this error and see in many places that you can ignore this error. However, I can't figure out how to ignore it so it will compile/assemble.
Can anyone tell me why this error is occuring when trying to run on a 16F886 and what to do about it?
Re: How to resolve assembler error 306?
Been asked a lot of time here.... it's not an error, it's a warning which can be disabled in MicroCode Studio or using the simple line bellow
@ ERRORLEVEL -306
check MPASM/MPLAB help file for all error/warning message description
Re: How to resolve assembler error 306?
Steve, I saw elsewhere that PBP does take care of it UNLESS you are using BRANCH or ASM in your program. I'm not using BRANCH anywhere, but I am using ASM-ENDASM to include some assembly statements in my PBP program..one example is when I use the DT_INTS-14. I tried turning off the warning per your assembly statement and FL no longer shows the warning as an unrecognized error, but I still get all kinds of assembly errors that are pointing at PBPPIC14.lib in some of them and mention a variable wsave not previously being defined and also indicates that "Chip has RAM in BANK1, BANK2, BANK3 but wsave1, wsave2, wsave3 were not found...which sounds like I still ave a page boundry problem. Suggestions?
Re: How to resolve assembler error 306?
post your code,
EDIT: open DT-INT file, usually you could need to comment out some lines...

Here is my code, but not quite sure what lines in DT_INTS-14.bas I would need to comment out??
Code:
'< FL_PIC16F886 >' ' First valid PIC found within the first 200 lines will
' highlight AND set device.
'< FL_PBPW >' ' OR < FL_PBPL >
'< FL_MPASM >' ' OR < FL_PM >

' -----------------------[ Program Description ]------------------------
' PICBASIC PRO program to set RTC & demo operation of a LCD/4-bit mode *
' 1) Initializes 2x16 or 2x8 LCD display (if installed) with EasyPic6.*
' 2) Time/date/Alarm1 must have already been programmed into the *
' DS1337 Real-time-clock before running this program. *
' (IMPORTANT: user must use available SetTimeDate program to *
' program DS1337 prior to programming this program into the MCU) *
' 3) Alarm1 from the DS1337 is used as RB2 interrupt on change by MCU.*
' 4) Also displays date/time on LCD (if installed) every second. *
' 5) Measures temperature on every Alarm1 interrupt and displays it. *
' 6) If battery is so low to drop Vr<=3.39 vdc, LED_RED will blink 5x *
' as a low voltage warning monitor. *

' Version 1.0 Started on 07/19/11
' ------------[ NOTES for use with EasyPic6 development board ]---------
' Make sure that SW6.8 on the EasyPic6 is set to ON position before
' powerup for LCD's requiring backlight.
'For use with 2x16 LCD (when installed):
' - Turn on Port Expander switches SW6.1,SW6.2,SW6.3,SW6.4 & SW6.5.
' - Turn on COG LCD 2x16 switches SW10.1, SW10.2, SW10.3, SW10.4,
' SW10.5 & SW10.6.
'For interface to DS1337 RTC:
' - TO provide battery backup, place two Shottky diodes in 'or'
' configuration between the Vdd (pin-8) of the DS1337 and the Vcc
' source and the + terminal of the backup battery.
' - I2C communication lines should be connected to 4.7K pull-ups.
' - DS1337 INTA & INTB lines should be connected to pull-up resistsors.
' - Turn off LEDs connected to I2C communication lines.

Re: How to resolve assembler error 306?
You have to read the error messages, they will tell you what to comment. then when you open the file, it is also well commented and says stuff like Comment this line if you get error such and such
Re: How to resolve assembler error 306?
Here is a list of my error messages. I don't see what they are telling me that I have to comment out. Are you saying that the well commented lines are in the .lst file after assembly? I am confused as to what file I need to open to read where the lines that need to be commented out are listed.

Re: How to resolve assembler error 306?
Since version 1.00 of DT_INTS-14, it is best if you DO NOT comment or un-comment lines in the include file.
Changing the include file can affect compiling with other chips that have different BANK configurations.
Instead, copy the wsave variables block from the file into your source code, and un-comment the lines that the compiler refers to in the errors.
Code:
;-- Place a copy of these variables in your Main program -------------------
;-- The compiler will tell you which lines to un-comment --
;-- Do Not un-comment these lines --
;---------------------------------------------------------------------------
;wsave VAR BYTE $20 SYSTEM ' location for W if in bank0
;wsave VAR BYTE $70 SYSTEM ' alternate save location for W
' if using $70, comment wsave1-3
' --- IF any of these three lines cause an error ?? ------------------------
' Comment them out to fix the problem ----
' -- Which variables are needed, depends on the Chip you are using --
;wsave1 VAR BYTE $A0 SYSTEM ' location for W if in bank1
;wsave2 VAR BYTE $120 SYSTEM ' location for W if in bank2
;wsave3 VAR BYTE $1A0 SYSTEM ' location for W if in bank3
' --------------------------------------------------------------------------
The errors you posted indicated to ADD wsave, wsave1, wsave2 and wsave3.
It also indicated "OR" change to wsave VAR BYTE $70. If you add that line, you don't need the other wsaves.
So a simple ...
Code:
wsave VAR BYTE $70 SYSTEM
in your code will suffice.
Also, the 16F886 doesn't have a Low Voltage Detect circuit (LVD). So LVD_INT cannot be used.
Re: How to resolve assembler error 306?
Thanks, Darrel. That solved the problem.
However, I might suggest that you flag this info on the DT_INTS-14 web site for others that may be having this problem. I checked there first to see if I could find anything related to these errors.

Thanks for pointing that out, Darrel. I see now that I have to find another way to detect low battery voltage. In that regard, I am wondering if their is some way to hook the battery output on my PCB to one of the comparator inputs and comparing it somehow to an internally generated reference voltage. I tried to study the Comparator section of the 16F886 data sheet to see if this was possible, but I got lost in the complexity of the comparator circuits and how to generate a CVref into it from internal circuitry.
Can you point me to any posts or tutorial that might explain how to do this?
Re: How to resolve assembler error 306?
Thanks, Darrel. I am embarassed to say I had forgotten all about this thread :o
