I used 16f877a chip before, and right now I am using 12f675 on my Picflash programmer, I wrote a program adopted from Moritz http://www.ccsinfo.com/forum/viewtopic.php?t=19801&highlight=12f675

when I configured all IDs as 0000, ID errors dispeared. how about others?

On the left bottom side of the PIC flash, there is a option configuration button, when I not check these items, certainly the program will pass, but the program is not work, nothing shown on my led, so, there should be some other problem, and I thnk I should check all these items, but how to solve the problem!

Thank you:
I am not using the same hex file, when I program the 12f675, I changed setting and compiled them acordingly. can you tell me exactly which part might affect it, or more directly, which part should I pay more attention to read on the datasheet?

Is 12f675 a 12 bit or 14 bit chip?

I thought it is 12 bits, but some guys in this group said it is 14bits? I got confused. It is 12 bits right?

Thank you:
So what is OSSCAL, and how to set up them, also the ID locations.

are there anyone can help me out of these error problem? I kind of got frustrate about it, but Still looking for start light shining somewhere?
[code]
#if defined(__PCM__)
#include <12F675.h>
#device ADC=10
#fuses INTRC_IO,NOWDT,NOPROTECT

#byte ADCON0 = 0x1F
#byte ANSEL = 0x9F
#byte CMCON = 0x19
#use delay(clock=20000000)

void main()
{
int16 Value=300;

ADCON0 = 0; // ADC off
ANSEL = 0; // GPIO pins 0,1,2 and 4 set to all digital
CMCON = 7; // Comparators off

//set_tris_a(0b00000111);//RA0, RA1, RA2 as Inputs RA3, RA4, RA5 as Outputs

setup_adc_ports(AN0_ANALOG );
setup_adc(ADC_CLOCK_INTERNAL );
set_adc_channel(0);
delay_ms(150); // Allow the channel to be aquired

output_high(pin_a5);
delay_ms (250);
output_low(pin_a5);
delay_ms(10);

while(1)
{
int32 i;
Value=read_adc();
delay_ms(10);

if (Value > 512)//If more than 50% Flash fast
{
output_high(pin_a1);
delay_ms(250);

output_low(pin_a1);

delay_ms(250);
}
else //if (Value < 513) Flash slow
{
output_high(pin_a4);
delay_ms (1500);
output_low(pin_a4);
delay_ms(1500);
}
}
}

Thank you?

anyone use the PICflash to write hex to PICeasy2 board? I have no problem with the 16f877a big board, but have these errors write to 12f675 small board, are there any setting change required? I connected the board using usb port.
