4.4.2 Digital I/O

void digHoutConfig(char configuration);

Configures a high-current output to be either a sinking or a sourcing output. This configuration informa-

tion is also used to initially set the output to the off state for the given hardware output configuration. The

configuration options are described below.

NOTE: Configuring a given output channel for tristate operation using the digHTriState-

Config function will override the configuration set by the digHoutConfig function.

NOTE: The brdInit function must be executed before calling digHOutConfig.

NOTE: You must execute the digHOutConfig function to set the high-current drivers to be

either sinking or sourcing. A runtime error will occur in digHOut if digHOutConfig has

not executed.

NOTE: The extra digital outputs resulting from the configuration of DIO00–DIO15 as digital out-

puts are sinking outputs only and cannot be configured with digHOutConfig.

PARAMETER

configuration is a 1-byte parameter where 4 bits are used for the high-current outputs HOUT0–

HOUT3.

Bit 3 = high-current output channel HOUT3

Bit 2 = high-current output channel HOUT2

Bit 1 = high-current output channel HOUT1

Bit 0 = high-current output channel HOUT0

(bits 4–7 are not used)

The high-current outputs can be configured to be sinking or sourcing outputs by setting the correspond-

ing bit to an 0 or 1: 0 = sinking, 1 = sourcing.

RETURN VALUE

None.
