| Bug in the 3.202 and 3.203 |
 Posted: Sat Jul 03, 2004 12:16 pm |

Hi,
I have a program that use the 82% the ROM in a PIC18F8720, I am using the version 3.200 and work ok!, but I put the new version 3.203 and my program not work. I see the follow difference in the LST files, in the version 3.200 the first line is a GOTO 1914C to the main function and this address is right!, but in the version 3.203 (3.202 too) the first line is a GOTO 18956 but this address not exist in the LST!!!!, the main function exist in the address 8956.
You can understand the problem?
Best Regards,

Why does your lst have MPASM at the top ?
The message about Stack: is also wrong...
!
If it is a bug then report it. |

Options -> File Formats -> Microchip
then you will see MPASM at the top |

18956 show up as 8956 might be just simple truncation instead of bug.
However, I did catch a bug new in 3.203 in case of large RAM usage, read my next post. |

| read_adc() bug in PCH 3.203 |
| Posted: Sun Jul 04, 2004 12:58 am |

To whom it may concern:
Bug report ... PCH 3.203 + PIC18F458
ADRESH is missing in read_adc() in case of BSR change is needed.
Same bug for read_adc( ADC_READ_ONLY )
| Code: | // bug_3203_BSR_read_adc.c by C-H Wu 2004/07/04
//
#include <18F458.H>
#fuses HS, PUT, NOLVP, NODEBUG
#device ADC=10 // select 10-bit AD results
int16 ad_data;
#byte ad_data = 0x300 // this line causes ADRESH missing !
#use delay ( clock = 20000000 )
#use rs232 ( baud = 115200, xmit=PIN_C6, rcv=PIN_C7 )
#zero_ram
void main()
{
setup_adc_ports ( A_ANALOG );
setup_adc( ADC_CLOCK_DIV_32 );
set_adc_channel( 0 );
while ( 1 )
{
// ad_data = read_adc(); // unmark this line will save the next line !!
// because bank select is no longer needed.
ad_data = read_adc(); // Bug ! MOVFF ADRESH,ad_data+1 is missing !
printf("\r\n AN0 = %lu ", ad_data); delay_ms(1000);
}
}
|
the LST file is
| Quote: | .................... while ( 1 )
.................... {
.................... // ad_data = read_adc(); // unmark this line will save the next line !!
.................... // because bank select is no longer needed.
....................
.................... ad_data = read_adc(); // Bug ! MOVFF ADRESH,ad_data+1 is missing !
0152: BSF ADCON0.2
0154: BTFSC ADCON0.2
0156: GOTO 0154
015A: MOVLB 3
015C: MOVFF ADRESL,ad_data
....................
.................... printf("\r\n AN0 = %lu ", ad_data); delay_ms(1000);
|
where is ADRESH ???
unmark the first line of read_adc(), the LST file turns out to be
| Quote: | .................... while ( 1 )
.................... {
.................... ad_data = read_adc(); // unmark this line will save the next line !!
0152: BSF ADCON0.2
0154: BTFSC ADCON0.2
0156: GOTO 0154
015A: MOVLB 3
015C: MOVFF ADRESL,ad_data <--- bug ! ADRESH is missing !
.................... // because bank select is no longer needed.
....................
.................... ad_data = read_adc(); // Bug ! MOVFF ADRESH,ad_data+1 is missing !
0160: BSF ADCON0.2
0162: BTFSC ADCON0.2
0164: GOTO 0162
0168: MOVFF ADRESL,ad_data
016C: MOVFF ADRESH,ad_data+1 <--- this is correct
....................
.................... printf("\r\n AN0 = %lu ", ad_data); delay_ms(1000);
|
Could there be more bugs of this kind in 3.203 ????
Best wishes
C-H Wu
p.s. I did send a bug report to CCS, but ... what day is today ?
Happy July the 4th !  |
