p ADAT port - should be 1-bit and clocked at 100MHz

oChan channel on which decoded samples are output

void adatReceiver44100(buffered in port:32 p, chanend oChan)

ADAT Receive Thread (44.1kHz sample rate).

The function will return if it cannot lock onto a 44,100/48,000 Hz signal. Normally

the 48000 function is called in a while(1) loop. If both 44,100 and 48,000 need to

be supported, they should be called in sequence in a while(1) loop. Note that the

functions are large, and that 44,100 should not be called if it does not need to be

supported.

This function has the following parameters:

p ADAT port - should be 1-bit and clocked at 100MHz

oChan channel on which decoded samples are output

void usb_midi(port ?p_midi_in,

port ?p_midi_out,

clock ?clk_midi,

chanend ?c_midi,

unsigned cable_number,

chanend ?c_iap,

chanend ?c_i2c,

port ?p_scl,

port ?p_sda)

USB MIDI I/O thread.

This function passes MIDI data from USB to UART I/O.

This function has the following parameters:

p_midi_in 1-bit input port for MIDI

p_midi_out 1-bit output port for MIDI

clk_midi

clock block used for clockin the UART; should have a rate of 100MHz

c_midi chanend connected to the decouple() thread

cable_number

the cable number of the MIDI implementation. This should be set

to 0.
