Hi, I need to be able to detect state changes of the CTS line.
I have been using the following simple app:
io.num = PL_IO_NUM_18_INT2 ' CTS input of the serial port 2
io.enabled=NO 'we configure this line as input (default)
dim x as low_high
do
x = io.lineget(PL_IO_NUM_18_INT2)
loop until x = LOW ' it's always HIGH no matter what
To alter the state of the CTS line I use an external circuit. It works for my PC after I anable the DTR line/pin. But how do I enable it on this device?
In simple terms, this means that when you use the secondary cover for the DS1000, it is guaranteed and certified to be waterproof, and can actually operate while immersed in water! It has been tested for immersion of 1.5 meters, and remained fully water-tight.
