Line Label Best Practices with Include Files

TSEYFARTH · Joined: 01 Jul 2006 Posts: 1054

Hello all,

Just starting to use Projects and Include files. In some cases, Line Labels are used. What is best practice for Line Labels, including those used by _Isr's, when using multiple include files?

Thank you,
Tim

hello,
could you be more explicit ?
what do you want ?
use gosub....label where label is in file include ?
or use loadlabel ?
Would you please add a small code example.

Hello Duval JP,

Thank you for your response. The following are some specific examples.
Tim

'********************************************************************************************
'* Timer0 '1mS Timer '8 Bit Timer
'*************************************************************************************************
Const Timer0reload = 125
Config Timer0 = Timer , Prescale = 64
On Ovf0 Timer0_isr
Enable Timer0

'********************************************************************************************
'* Timer1 '500uS 16bit Timer
'*************************************************************************************************
Const Timer1reload = 4000
Config Timer1 = Timer , Prescale = 1
Load Timer1 , Timer1reload
On Ovf1 Timer1_isr

'**********************************************************************************************
'**********************************************************************************************
'* Timer0 '1mS Timer '8 Bit Timer
Timer0_isr: '1 mS Timer
Load Timer0 , Timer0reload
If Ack_interval_counter = 10000 Then Ack_interval_counter = 0
If Wait_4_ack = 1 Then Incr Ack_interval_counter
Return

'**********************************************************************************************
'**********************************************************************************************
'* Timer1 '500uS 16bit Timer
Timer1_isr: '500 uS Timer
Load Timer1 , Timer1reload
If Strt_debounce > 0 Then Decr Strt_debounce
Return

'*************************************************************************
Receive_data:
'poll RFM12 for Rx data.
Rfm12_get_status_bit
If Rx_status_bit = 1 Then
Rfm12_rx Rxbuffer(1)
Alarm_data_received = 1
Rxbuff(1) = Rxstring
End If
Return

'*************************************************************************
Isr_ffit:
Gosub Receive_data
Return

Hi,

I usually split my programs using includes based on functionality:-

l2c_bus.lib - contains the low level i2c routines
IO.lib - contains the alias definitions for PIN/ADC's
Sensors.lib - contains the Scaling/Smoothing and alarming routines
SF04.lib - contains the Sensirion flow sensor routines
Amsys.lib - contains the Pressure sensor routines
Sm.lib - contains the "Smart bus" battery routines

The main program then just consists of the code to setup the AVR, Interrupt service routines and the State machine handler.
The example above if doe a project I'm currently working on that at the moment consists of about 6000lines of code.

Breaking the cod down into functional groups makes testing a lot easier. I can create a small test program, add the required sensors and test it.

For my "test board" I have done configurations and subroutines in files that I include only. Configuration for Lcd, Timers and what ever can be included before Do Loop and Sub`s after Loop. It does not matter whether it's IRQ. For new projects do not have to write this again

Hello i.dobson and EDC,

Thank you for your replies! Interesting, that EDC includes.bas files. So it appears that you can include both .inc and .bas files. I thought that only 1 .bas file could be in the project.

i.dobson, as you described you put line labels like those used for ISR's in the main .bas, from my brief work, that seemed to be the only place they would work. I also noted that your file names are of .lib - does this mean that any file extension can be used?

EDC, in you include.bas files. In those, do you have also ISRs, timers and other items as necessary - or are they only in your main .bas file?

In both cases, this was quite enlightening! I think it will make it much easier to work on a large project having the ability to organize in to file size chunks. Also nice is that the same files can be used elsewhere when necessary as you both did.

Thanks again for your replies!
Tim

Hi Tim,

Woops your right, the file names are with .inc not .lib

Hi Ian,
Thanks for the clarification. I had not tried it yet, but it would be kind of cool if you could use different file extensions. Especially since the whole file name has to be stated in the $Include line.

Do all &Include files need to be in the same folder as the Project / main .bas file? If not is it correct that the source has to have a hard coded full path to the files.

In your case, I can see there the above would come into play since the $Includes are used in many projects, probably at one time. So a central repository would make sense. Is this what you do?

Thanks again Ian,
Tim

Hi,

I've never tried with different directories. I usually just copy the required modules from my central module directly into the project directory.

I work for pharmaceutical companies and testing/documentation/validation if very important for them and using standard/pre-tested modules makes my life much easier. When I start testing/documenting a project I can just pull in the modules documentation and set a reference to the previous tests performed, rather than having to test everything again. I still need to test the interface to the main application but not the low level code within the module.

I add a good practice :

see the help : "on interrupt"
"Finally some tips :
* when you use a timer interrupt that occurs each 10 uS for example, be sure that the interrupt code can execute in 10 uS. Otherwise you would loose time.
* it is best to set just a simple flag in the interrupt routine and to determine it's status in the main program. This allows you to use the NOSAVE option that saves stack space and program space. You only have to Save and Restore R24 and SREG in that case.

Using $nocompile bas files is like hiding some knowed code from eyes. Compiler can hide some configurations but with $nocompile You can do more because override this. Eg. for test board I have Mega328p and target device is Mega8 whitch have diferent names for timer registers. In main Bas file I include config for Timer Isr and diferrent connection for Lcd.
