50 SBC BL2600
Sets the state of a high-current digital output (HOUT0–HOUT3) to a logic 0, logic 1, or high impedance.
Remember to call the
brdInit
and the
digHoutConfig
functions before executing this function.
A runtime error will occur for the following conditions:
1. channel or state out of range.
2. brdInit or digHoutConfig was not executed before executing digHout .
3. If you try to use a channel that is configured as a tristate output by digHTriStateConfig .
PARAMETERS
channel
is the output channel number (0–3).
state
sets a given channel to one of the following output states depending on how the output was con-
figured by digHoutConfig .
Sinking configuration:
0 = connect the load to GND
1 = put the output in a high-impedance state
Sourcing configuration:
0 = put the output in a high-impedance state
1 = connects the load to +K(0–3)
RETURN VALUE
None.
