Storage Problems

Hi,

I have written a code to sample P00, P01, P02 ADC Values.

This code is triggered by codless AT+TMRSTART=0,0,1

The code looks like:

else if(user_compare_cmd("TMRSTART",3,3))
{

uint8_t timer_id = ahtoi((char*)argument_array[0]);
uint8_t指数= ahtoi ((char *) argument_array [1]);
times_seconds= ahtoi((char*)argument_array[2]);

if(index == 0)
codeless_env.tmr[timer_id] = app_easy_timer(ahtoi((char*)argument_array[2]),throw_command0);
else if(index == 1)
codeless_env.tmr[timer_id] = app_easy_timer(ahtoi((char*)argument_array[2]),throw_command1);
else
user_reply(tempstr, false);
if(index < 4)
user_reply(tempstr, true);

// INPUT PINS
GPIO_ConfigurePin((GPIO_PORT)0, (GPIO_PIN)0, INPUT, PID_GPIO, false );
GPIO_ConfigurePin((GPIO_PORT)0, (GPIO_PIN)1, INPUT, PID_GPIO, false );
GPIO_ConfigurePin((GPIO_PORT)0, (GPIO_PIN)2, INPUT, PID_GPIO, false );

// ADC INIT

adc_init(GP_ADC_SE, 0, 0);
}

and in the callback code:
void throw_command0()
{
codeless_env.suppress_response = true;
adc_enable_channel(0);
adc_get_sample();
int length = (int)( sizeof(ADC_values_1) / sizeof(ADC_values_1[0]));
for(int i = 0; i < length; i++ ){
adc_enable_channel(0);
adc_get_sample();
一个DC_values_1[i] = adc_get_sample();
adc_enable_channel(1);
adc_get_sample();
一个DC_values_2[i] = adc_get_sample();
adc_enable_channel(2);
adc_get_sample();
一个DC_values_3[i] = adc_get_sample();
}
for(int i = 0; i < length; i++ ){
arch_printf("%i,%i,%i\r\n",ADC_values_1[i],ADC_values_2[i],ADC_values_3[i]);
}
codeless_env.tmr[0] = app_easy_timer(times_seconds,throw_command0);
codeless_env.suppress_response = false;
}

The Timer restarts itself in the callback function.

It works fine for a periode of time and the the program crashes.

The arrays are global defined:
int ADC_value_1[30];

if i debug it with IDE Keil and run it may the storage will be full or the adc stops working?
一个ny ideas where the problem occures?

arch_printf() caused the problem!

Best regards
