Function Documentation

void __attribute__

(

(__interrupt__, auto_psv)

)

Save the AD buffer registers in differents arrays.

Interrupt from timer3.

Interrupt from timer2.

Parse the chained list of agenda.
Increment counter only.
Check if agenda has to be treated according to the cycle value and current counter value.
Do it for number of cycle positive or null.
Check if a service has to be activated.

unsigned char e_ad_is_acquisition_completed

(

void

)

To know if the ADC acquisitionn is completed.

Returns:

0 if the new acquisition is not made, 1 if completed.

unsigned char e_ad_is_array_filled

(

void

)

To know if the ADC acquisitionn of microphone only is completed.

Returns:

0 if the new acquisition is not made, 1 if completed.

void e_ad_scan_off

(

void

)

Disable the ADC conversion.

void e_ad_scan_on

(

void

)

Enable the ADC conversion.

void e_init_ad_scan

(

unsigned char

only_micro

)

Initialize all the A/D register needed.

Set up the different ADC register to process the AD conversion by scanning the used AD channels. Each value of the channels will be stored in a different AD buffer register and an inturrupt will occure at the end of the scan.

Parameters:

only_micro

Put MICRO_ONLY to use only the three microphones at 33kHz. Put ALL_ADC to use all the stuff using the ADC.
