How can I read in this mode - AD conv. SEQM2

[skyforme]

Hello

I want to read four samples if interrupt occurs.
But it always read the same strange thing.

int16 value1,v2,v3,v4;

// This function turns the LEDs on and off
void flash_led() {

output_low(TOGGLE_PIN);
delay_us(value1*10);
output_high(TOGGLE_PIN);
delay_us(value1*10);
}

#int_AD
AD_isr()
{

set_adc_channel(1);
value1 = Read_ADC(ADC_READ_ONLY);
set_adc_channel(0);
v2 = Read_ADC(ADC_READ_ONLY);
set_adc_channel(6);
v3 = Read_ADC(ADC_READ_ONLY);
set_adc_channel(7);
v4 = Read_ADC(ADC_READ_ONLY);
//value = Read_Adc();
flash_led();
// Start the initial conversion
Read_ADC(ADC_START_ONLY);

}


void main()
{

setup_adc_ports(sAN0|sAN1|sAN2|sAN3|sAN4|sAN5|sAN6|sAN7|sAN8|VSS_VDD);
setup_adc(ADC_CLOCK_INTERNAL|ADC_TAD_MUL_0|ADC_CONT_A_B_C_D|ADC_INT_EVERY_FOUR);
setup_spi(FALSE);
setup_wdt(WDT_OFF);
setup_timer_0(RTCC_INTERNAL);
setup_timer_1(T1_DISABLED);
setup_timer_2(T2_DISABLED,0,1);
enable_interrupts(INT_AD);
enable_interrupts(GLOBAL);
setup_low_volt_detect(FALSE);
setup_oscillator(False);

output_high(PIN_D1);
output_high(PIN_D2);
output_high(PIN_C0);


// Start the initial conversion
Read_ADC(ADC_START_ONLY);
while(1)
{}
}

It's the code..
but it alwyas shows the same thing and blinking the LED with strange rate (not pot reference).

Thank you

The largest value that 'delay_us' can accept from a variable is 255. You are therefore seeing wrapping of the counter, giving variable length delays as the ADC changes. Use something like:
