/a value of b00111 (=d7), and 5 bits will be updated.

will need to initialize the flexible I/O to a known pin

tion. One way to do this is with the following pseudocode:

IMERS_ENABLED, 0, 0);

NTER_PIN_OFFSET, 0, 0);

Handle, LJ_ioPUT_CONFIG, LJ_chTIMER_CLOCK_BASE, LJ_tc24MHZ, 0);

Handle, LJ_ioPUT_CONFIG, LJ_chTIMER_CLOCK_DIVISOR, 0, 0);

Put (lngHandle, LJ_ioPUT_COUNTER_ENABLE, 0, 0, 0);

0, 0, 16);

is disables all timers and counters, sets the timer/counter pin offset to 0, sets the timer clock

is using the following IOType created exactly for this

urpose, which does the same thing as the 8 function calls above:

here are two IOTypes used to write or read general U3 configuration parameters:

J_chPRODUCTID

write and read the local

hLOCALID, &dblValue, 0);

e IOTypes to retrieve a command/response analog input reading are:

//Configure FIO2-FIO4 as analog, and FIO5-FIO6 as digital, without

//configuring any other bits. That means a starti

ePut (lngHandle, LJ_ioPUT_ANALOG_ENABLE_PORT, 2, 7, 5);

Because of the pin configuration interaction between digital I/O, analog inputs, and

timers/counters, many software applications

ePut (lngHandle, LJ_ioPUT_COUNTER_ENABLE, 1, 0, 0);

Put (lngHandle, LJ_ioPUT_DAC_ENABLE, 1, 0, 0);

ePut (lngHandle, LJ_ioPUT_ANALOG_ENABLE_PORT,

base to 24 MHz (no divisor), sets the timer clock divisor to 0, disables DAC1, and sets all

flexible I/O to digital. A simpler option

ePut (lngHandle, LJ_ioPIN_CONFIGURATION_RESET, 0, 0, 0);

LJ_ioPUT_CONFIG

LJ_ioGET_CONFIG

The following constants are then used in the channel parameter of the config function call to

pecify what is being written or read:

LJ_chLOCALID

LJ_chHARDWARE_VERSION

LJ_chSERIAL_NUMBER

LJ_chFIRMWARE_VERSION

LJ_chBOOTLOADER_VERSION

LJ_chLED_STATE

Following is example pseudocode to ID:

//Set the local ID to 4.

ePut (lngHandle, LJ_ioPUT_CONFIG, LJ_chLOCALID, 4, 0);

eGet (lngHandle, LJ_ioGET_CONFIG, LJ_c
