| PIC16F19197 PORTF can not read input |

Hi,
I try read pin_f4 pin but not read. You see my c code and compare to assembly code. I want read pin_f4 but reading pin_a4.
| Code: |
.................... if (input(PIN_f4)==1)
0B1D: MOVLB 05
0B1E: BTFSS 0C.4 (pin_a4 address!!)
0B1F: GOTO 32A
.................... {output_high(pintimeronoffled);
0B20: MOVLW C3
0B21: MOVLB 00
0B22: MOVWF 14
0B23: BSF 1A.3
|
Thanks

You should post a small program that shows your code AND your compiler version number.
If you have a variable you name PIN_f4 that would not be the same as PIN_F4, if you've got #CASE in your code. I have been caught with 'case sensitive before...
The other possibilty is an error in the compiler. |

Thanks temtronic,
You see if i use portc compare asm file, portc BTFSS 0E.4 address is right. When i use portf, write wrong address:
| Code: |
.................... if (input(PIN_C4)==1)
0B1D: MOVLW C3
0B1E: MOVWF 14
0B1F: BTFSS 0E.4
0B20: GOTO 329
.............................
|
it's my main procedure.
| Code: |
#ZERO_RAM
void main()
{
setup_oscillator(OSC_HFINTRC_32MHZ );
setup_dac(DAC_OFF);
setup_ccp1(CCP_OFF);
setup_ccp2(CCP_OFF);
setup_lcd(LCD_DISABLED);
setup_adc(ADC_CLOCK_INTERNAL | ADC_CLOCK_DIV_2 |NO_ANALOGS_P2);
setup_adc_reference(VSS_VDD);
setup_adc_ports(sAN0|sAN1|sAN2);
set_analog_pins(PIN_A0,PIN_A1,PIN_A2);
setup_zcd(ZCD_ENABLE|ZCD_INT_L_TO_H);
set_tris_f(0b00011111);
set_tris_a(0b11111111);
set_input_level_f(0xFF);
set_slow_slew_f(0b00000000);
set_open_drain_f(0b00000000);
setup_rtc(RTC_ENABLE | RTC_CLOCK_SOSC );
setup_spi(SPI_SS_DISABLED);
setup_wdt(WDT_OFF);
setup_timer_0(T0_INTERNAL|T0_DIV_8);
setup_timer_1(T1_INTERNAL |T1_DIV_BY_2);
setup_timer_2(T2_DISABLED,0,1);
setup_comparator(NC_NC_NC_NC);
disable_interrupts(INT_TIMER2);
enable_interrupts(INT_TIMER1);
enable_interrupts(INT_TIMER0);
disable_interrupts(INT_EXT);
enable_interrupts(INT_ZCD);

It's a compiler bug. The following work-around code will read the correct
port address. With this method, you have to set the TRIS manually, but
you're already doing that in your main() program anyway.
| Code: | #include <16F19197.h>
#fuses NOWDT
#use delay(internal=4M)
#byte PORTF = getenv("SFR:PORTF")
//===============================
void main(void)
{
int8 temp;
temp = bit_test(PORTF, 4);
while(TRUE);
}
|
This bug should be reported to CCS. |

Thanks PCM programmer,
it's work.
| Code: |
.................... if (bit_test(PORTF, 4))
0B81: BTFSS 11.4 |

there is similar problem within PORTH!! I solved it with the method. Thanks

Please report both to CCS.
It is very difficult for them to keep up with all the nuances of new PIC's,
so feedback from us is vital.  |

Yes you are right. I reported to CCS. I think I am the first CCS user to use the PIC16F19197
Thanks

Yes.
This is why you will see a lot of the 'old hands' here staying with the last generation chips, rather than leaping to new ones. With the rate that MicroChip launches new types, it is very hard for CCS to keep up, and even harder to get everything right... |
