Built-in Functions
Returns:
Function:
An int16. If pair is used 1 will be return if ADC is done with conversion, 0 will be
return if still busy. If pair isn't use it will return a bit map of which conversion are
ready to be read. For example a return value of 0x0041 means that ADC pair 6,
AN12 and AN13, and ADC pair 0, AN0 and AN1, are ready to be read.
Can be polled to determine if the ADC has valid data to be read.
Availability: Only on dsPIC33FJxxGSxxx devices.
Requires:
None
Examples:
int16 result[2]
setup_high_speed_adc_pair(1,
INDIVIDUAL_SOFTWARE_TRIGGER);
setup_high_speed_adc( ADC_CLOCK_DIV_4);
read_high_speed_adc(1, ADC_START_ONLY);
while(!high_speed_adc_done(1));
read_high_speed_adc(1, ADC_READ_ONLY, result);
printf(“AN2 value = %LX, AN3 value = %LX \n\ r”,result[0],result[1]);

Syntax:

setup_high_speed_adc(), setup_high_speed_adc_pair(), read_high_speed_adc()
i2c_init([stream],baud);
Parameters: stream – optional parameter specifying the stream defined in #USE I2C.
baud – if baud is 0, I2C peripheral will be disable. If baud is 1, I2C peripheral is initialized and
enabled with baud rate specified in #USE I2C directive. If baud is > 1 then I2C peripheral is
initialized and enabled to specified baud rate.

specified in //#USE I2C
i2c_init(500000); //initialize and enable I2C peripheral to a baud rate of
