PCD
mode – Optional parameter, if used the values may be:
· ADC_START_AND_READ (starts conversion and reads result)
· ADC_START_ONLY (starts conversion and returns)
· ADC_READ_ONLY(reads conversion result)
result – Pointer to return ADC conversion too. Parameter is optional, if not used
the read_fast_adc() function can only perform a start.
Returns:
Function:
Undefined
This function is used to start an analog to digital conversion and/or read the digital
value when the conversion is complete. Calls to setup_high_speed_adc() and
setup_high_speed_adc_pairs() should be made sometime before this function is
called.
When using this function to perform an individual start and read or individual start
only, the function assumes that the pair's trigger source was set to
INDIVIDUAL_SOFTWARE_TRIGGER.
When using this function to perform a global start and read, global start only, or
global read only. The function will perform the following steps:
1.
Determine which ADC pairs are set for
GLOBAL_SOFTWARE_TRIGGER.
2.
3.
4.
Clear the corresponding ready flags (if doing a start).
Set the global software trigger (if doing a start).
Read the corresponding ADC pairs in order from lowest to highest
(if doing a read).
5.
Clear the corresponding ready flags (if doing a read).
When using this function to perform a individual read only. The function can read
the ADC result from any trigger source.
Availability: Only on dsPIC33FJxxGSxxx devices.
Requires:
Examples:
Constants are define in the device .h file.
//Individual start and read
int16 result[2];
setup_high_speed_adc(ADC_CLOCK_DIV_4);
setup_high_speed_adc_pair(0,
INDIVIDUAL_SOFTWARE_TRIGGER);
read_high_speed_adc(0, result); //starts conversion for AN0 and AN1
and stores
//result in result[0] and result[1]
//Global start and read
int16 result[4];
setup_high_speed_adc(ADC_CLOCK_DIV_4);
