how i convert boolean to string ?

[smalhao]

I have a digital temperature sensor connected to my digital output on the NI-9381 module, I get the value in True or False, I convert it to a String and I get the value of 0 or 1, however I wanted to receive the full value of 0s and 1s in order to calculate the temperature received, is there any way to get this value in 0s and 1s? next image from my cast to String

What do you mean by "full value of 0s and 1s"?   It is a boolean.  It is only a 0 or a 1.

If you want to calculate the temperature received, you'll need a numeric data type, not a boolean.

How i convert a True/False in a Numeric  in a digital port in CompactRIO (DIO0 example)

I tried make a search of that and don't find anything.

[RavensFan]

A digital input is either high or low, on or off, true or false.  0 or 1.

Are you trying to read a stream of digital data, like a serial port?

[smalhao]

Yes, i have my sensor DS18B20 connected to a serial port DB37 (NI-9381 Module), and i need extract the value of temperature.

Hi smalhao,

i have my sensor DS18B20 connected to a serial port DB37 (NI-9381 Module), and i need extract the value of temperature.

The DS18B20 supports a "1-Wire" bus.

The NI9381 is NO SERIAL PORT device. It's a multi-function device. It uses a DSub37 connector for all its IO signals…

The NI9381 supports DIO with 1MHz sample rate: you may try to develop your own signal reading routine to read data from your sensor…

Have you considered to read the manuals for all your devices?

So how do you expect a single boolean value to give you a string of serial data?

You need to do a time digital acquisition where you record a digital waveform.  Then figure out the code to parse the digital values into the individual bits, and then decode the stream of bits.  I imagine, start, stop and parity bits all come into play.

I have a feeling this might be over your head.  Does this sensor device supply any hardware to connect to a regular serial port?

I tried to read the dataheets of the NI-9381, and on the analog pins I have analog sensors and I have to give them the temperature values ​​and now I intend to get the temperature value on the digital pins but only when I try to build the code, the digital pin only TRUE or FALSE

The image show the digital pin where is it connected the sensor DS18B20

The output is True or False, and i don't know how i convert to a value numeric

You can't just read it once.  You need to do a continuous read of the digital input.

Have you looked in the example finder for examples on how to continuously read digital inputs?

[smalhao]

No, i don't find anything about that 😞
