| Problem with PIC10f222 |
 Posted: Tue Apr 27, 2010 7:40 am |
 |
|
I am not able to program pic10f222. The code is properly compiled with zero warning and error. But I am not getting the desired results. All the pins except the Gnd remains high. Even toggling any pin doesn't work. Even I cannot make any output pin low. Here is the code. I am using ccs v4.088. Please help.
| Code: |
#include <10F222.h>
#device adc=8
#FUSES NOWDT //No Watch Dog Timer
#FUSES NOMCLR //Master Clear pin used for I/O
#FUSES NOPROTECT //Code not protected from reading
#FUSES NOMCPU //Master Clear Pull-up disabled
#FUSES IOSC4 //INTOSC speed 4 MHz
#use delay(clock=4000000)
#include "C:\Documents and Settings\Administrator\My Documents\iotest\main.h"
void main()
{
setup_adc_ports(NO_ANALOGS);
//setup_adc(false);
setup_timer_0(RTCC_INTERNAL|RTCC_DIV_1);
// TODO: USER CODE!!
while(true)
{
output_high(PIN_B0);
delay_ms(50);
output_low(PIN_B0);
delay_ms(50);
}
} |

What hardware are you using to program the PIC?

Try this program. It should blink an LED on pin B0.
| Code: |
#include <10F222.H>
#fuses IOSC4,NOWDT,NOMCLR
#use delay(clock=4000000)
#define set_options(value) {#ASM \
MOVLW value \
OPTION \
#ENDASM}
//=========================
void main()
{
set_options(0xDF); // Enable pin B2 for normal i/o
setup_adc_ports(NO_ANALOGS);
while(1)
{
output_high(PIN_B0);
delay_ms(500);
output_low(PIN_B0);
delay_ms(500);
}
} |

I tested it with vs. 4.073, which is the free version of PCB that comes with
MPLAB 4.086. I used an ICD2 to program it.
What happens if you compile my test program, program the PIC, and
then use the ICD2 to do a Verify operation. Does it verify OK ?
After you finish programming the PIC, do you click on the "Release from
Reset" button in MPLAB ? This will allow the PIC to run. However, since
Pin B0 is also used by the ICD2 for ICSP Data, you should disconnect
the ICD2 from the 10F222 board in order to run the test.
If that doesn't help, then compile the program that I posted with your
version (v4.088), and post the .LST file. |

I notice you changed the #fuses to enable MCLR. Do you have a 10K
resistor on the MCLR pin ? You need one.
The symptoms you described would possibly occur if the PIC was held
in reset. With MCLR enabled, I wonder if you're missing the 10K pull-up
on the MCLR pin ? |

I have changed the code . This is the new lst file.Even then it is not working.
I have also replaced the IC.and checked.Everytime all the pins except GND(Pin no2) shows high. I tried the same code of reading analog from pot and changing output in PIC12F675. It is working fine. I am not able to figure out why the code is not working with pic10f222.

Sir,
can you send a hex file for the program you build which toggles LED at pin 1. email id - spradecom.rnd@gmail.com
If your hex works then there is problem in the compiler or our hardware set up. If your HEX doesnt work then our ICs are faulty |

Sir,
we are assigning AN0 as a analog input. But it always remains high. Is it that the ICSPDAT pin is continuous high. What steps to do to work pin no 1 as analog input after programming ?
| Code: |
#device adc=8
#FUSES NOWDT //No Watch Dog Timer
#FUSES NOMCLR //Master Clear pin used for I/O
#FUSES NOPROTECT //Code not protected from reading
#FUSES NOMCPU //Master Clear Pull-up disabled
#FUSES IOSC4 //INTOSC speed 4 MHz
#use delay(clock=4000000)
unsigned int8 value ;
void main()
{
setup_adc_ports(sAN0);
setup_adc(true);
setup_timer_0(RTCC_INTERNAL|RTCC_DIV_1);
// TODO: USER CODE!!
while(true)
{
set_adc_channel(0);
delay_ms(10);
//
value = Read_ADC();
output_high(PIN_B2);
delay_ms(value);
output_low(PIN_B2);
delay_ms(255-value);
}
} |

| The ADC value always remains high even if not input is given. the Pin shows zero voltage. then how the value in ADRESH is always high |
