DCI
DCI is an interface that is found on several dsPIC devices in the 30F and the 33FJ families. It is a
multiple-protocol interface peripheral that allows the user to connect to many common audio
codecs through common (and highly configurable) pulse code modulation transmission protocols.
Generic multichannel protocols, I2S and AC’97 (16 & 20 bit modes) are all supported.
Relevant Functions:
setup_dci(configuration, data
size, rx config, tx config,

read_adc(mode)
adc_done()
Relevant Preprocessor:
#DEVICE ADC=xx
Relevant Interrupts:
INT_DCI
Relevant Include Files:
None, all functions built-in
Relevant getenv() parameters:
None
Example Code:
signed int16 left_channel, right_channel;
dci_initialize((I2S_MODE | DCI_MASTER | DCI_CLOCK_OUTPUT |
SAMPLE_RISING_EDGE | UNDERFLOW_LAST | MULTI_DEVICE_BUS),DCI_1WORD_FRAME
| DCI_16BIT_WORD | DCI_2WORD_INTERRUPT, RECEIVE_SLOT0 | RECEIVE_SLOT1,
TRANSMIT_SLOT0 | TRANSMIT_SLOT1, 6000);
…
dci_start();

while(1)

dci_read(&left_channel, &right_channel);
dci_write(&left_channel, &right_channel);
Initializes the DCI module.
Sets the available adc pins to be analog or digital.
Specifies the channel to be use for the a/d call.
Starts the conversion and reads the value. The mode can also
control the functionality.
Returns 1 if the ADC module has finished its conversion.
Configures the read_adc return size. For example, using a PIC
with a 10 bit A/D you can use 8 or 10 for xx- 8 will return the most
significant byte, 10 will return the full A/D reading of 10 bits.
Interrupt fires on a number (user configurable) of data words received.
