The following examples show you how to set the output pin using the
SerialOutBlock()
instruction.
CRBasic example for setting the output pin
SerialOutBlock
(32, 1, 0)
'This will set the spare output pin high
SerialOutBlock
(32, 0, 0)
'This will set the spare output pin low
The preceding two example lines of code will set the output pin on the SDM-SIO2R high then low
respectively on the SDM-SIO2R device set to address 0 on its rotary switch.
Any value greater than 1 will set the output pin high, but usually the number 1 is used, as this will
improve the readability of the code.
