Hi.
I would like to use the Arduino bitWrite function, but have been unable to find a way to do this so as an alternative I tried to convert a Boolean Array to the corresponding number and this seems to be getting uneccessarily complicated.
Am I missing a simple solution somewhere?
Thanks

Can you confirm which VI you are using? There is no bitWrite VI. There is a Digital Write.vi which is for a single pin, and a Digital Write Port.vi which is for writing 8 bits at a time. The latter is probably what you are looking for.

Hi Steffan.
Thanks for the prompt reply. Sorry for the delay in getting back to you.
It is not the "Digital Write Port" I want to use, but the "bitWrite" and "bitRead" functions which appear in the Arduino language but do not have a corresponding LabVIEW function.
What would you suggest as the simplest way to implement this?
Thanks.
Regards

If you are operating on a variable/wire, then I would think you could easily do this with LabVIEW primitives, like and AND gate, and make it a subVI. Those functions just write and read a single bit in a variable. If you are trying to write/read to and from a digital port, possibly for speed, you could make a custom library to wrap the bitWrite and bitRead Arduino functions. Take a look at the help manual for instructions on making your own library.
