Flowcode + MPLAB compile errors

[chico]

Hello -

There is something I don't understand about Flowcode. If I try to compile my Flowcode C source in MPLAB, some of the variables that Flowcode generates are too long for the Hi-Tech compiler to handle.

In the code below, the compiler gives "Conflicting Declaration" errors for different variables generated by Flowcode. For example, "//ADC(0): //Macro function declarations" contains:

Code: Select all

void FCD_ADC0_SampleADC();
MX_UINT8 FCD_ADC0_ReadAsByte();
MX_UINT16 FCD_ADC0_ReadAsInt();
MX_FLOAT FCD_ADC0_ReadAsVoltage();
void FCD_ADC0_ReadAsString(MX_CHAR* FCR_RETVAL, MX_UINT8 FCR_RETVAL_SIZE);
void FCD_ADC0_ADC_RAW_Configure_Channel();
MX_UINT8 FCD_ADC0_ADC_RAW_Sample_Channel_Byte();
MX_UINT16 FCD_ADC0_ADC_RAW_Sample_Channel_Int();
MX_UINT8 FCD_ADC0_ADC_RAW_Average_Channel_Byte(MX_UINT8 NumSamples, MX_UINT8 DelayUs);
MX_UINT16 FCD_ADC0_ADC_RAW_Average_Channel_Int(MX_UINT8 NumSamples, MX_UINT8 DelayUs);
void FCD_ADC0_ADC_RAW_Disable_Channel();

…which causes the compiler to generate the following errors:

Code: Select all

…..(no more errors, just warnings….)

Since these are generated by Flowcode and not by the user, how can the user get the compiler to recognize them as separate variables?

Hello,

It looks like these lines in the C file are to blame.

984
1098
...

Can you post up the C file and hopefully I can help to spot what's going wrong for you.

Thanks for the response.

Actually, 984 and 1098 are the compiler error codes. The problem lines are listed at the end of the error messages in the HT compiler. So in this case, the problematic lines are 334, 335, 336, 336,557, and 583. The first three are definitions and the last two are routines:

Code: Select all

334:  MX_UINT8 FCD_ADC0_ADC_RAW_Sample_Channel_Byte();
335:  MX_UINT16 FCD_ADC0_ADC_RAW_Sample_Channel_Int();
336:  MX_UINT8 FCD_ADC0_ADC_RAW_Average_Channel_Byte(MX_UINT8 NumSamples, MX_UINT8 DelayUs);

556:  MX_UINT16 FCD_ADC0_ADC_RAW_Sample_Channel_Int()
557:  {
558:  	
559:		return FC_CAL_Sample_ADC( 1 );	//Perform Sample - Return as MX_UINT16
560:
561:  }

582:  MX_UINT16 FCD_ADC0_ADC_RAW_Average_Channel_Int(MX_UINT8 NumSamples, MX_UINT8 DelayUs)
583:  {
584:  	
585:  		MX_UINT32 average = 0;
586:  		MX_UINT8 count;
587:  
588:  		for (count=0; count<NumSamples; count++)
589:  		{
560:  			average = average + FC_CAL_Sample_ADC( 1 );					//Perform Sample - Return as MX_UINT16 - add to average
561:  
562:  			if (DelayUs)
563:  				delay_us(DelayUs);										//If delay is not 0 then pause between samples
564:  		}
565:  		average = average / count;
566:  
567:  		return (average & 0x1FFF);										//Return average as MX_SINT16
568:  
569:  }

I'm not a compiler genius, but it seems to me that the compiler can't handle the long variable names. I've been examining the compiler manual but can't find the part that says how many characters are allowed for definitions.

Does it make sense to you? I saw another post that seemed to indicate a similar issue:

Sorry to bother you but this problem will keep me from using Flowcode....

Could you try adding -N 50 to the compiler command line? This should increase the number of significant characters in the identifiers from the default 31 characters to 50 characters. (reference)

Ah, thank you for the reference. I hadn't been able to find that info before.

I found the MPLAB "Identifier Length" menu setting under: Project > Build Options > Compiler > (filename.c) > Identifier Length

...and it worked! Errors went away. Thanks for that.

NEXT ERROR (now that the compiler can proceed) is a linker error, "Unknown Record Type" (MX_FLOAT FCV_WATER_TEMP_VOLTAGE;):

The source error line (142):

Any thoughts on this error? I'm not sure I understand how Flowcode defines these MX types...

OK, I found the problem with this error. I had neglected to remove the Flowcode libraries necessary for compilation with BoostC. They aren't needed with Hi-Tech C. Doh!

Anyway, now I can compile my file inside of MPLAB with Hi-Tech v9.65 and v9.80 as well as BoostC.

Thanks for the help, everyone.
