Hello,

I'm trying to create a node that will keep the date and time and spit out a text line for future nodes to use. I'm also trying to make it so I can change the date and time by inputting some text variables and a second code block connected to a trigger.

So ultimately I have the main code block that keeps the time based off a trigger connected to a timer and a second code block that resets the time variable when a second trigger is pressed. The problem seems to be though that when the second trigger is hit, it doesn't execute the second code block.

I don't know if I explained that well enough, but if anyone can provide some insight, it would be awesome.

Thanks,

You're getting into new territory for me. I don't know much about keeping actual clock time with an embedded processor but I'm worried that there will be enough drift to cause problems. Embrio is pretty darn accurate when it comes to running code over and over, say 64 times per second, but there will be some microseconds off each time which will add up. I think for accurate clock keeping you might need an external piece of hardware.

I'm also not sure about how you're using the text inputs for the time input pieces. This situation is starting to convince me that Embrio really does need other number input types than 0.0 to 1.0 activations, this seems like a pretty bad abuse of the text input. What exactly are you using this clock for?

If it's working for you that's great but I think there's some room for improvement here on Embrio's side. I've been really conflicted about the idea of adding other numeric input and output types but I'm starting to think it might be necessary, I hate to see people having to abuse text inputs like this to do what they are trying to do. I think I'll try an integer input/output type soon for situations like this.

Yeah I used to think that when values came into Embrio they needed to be transformed from their native range to 0.0 to 1.0, then when they leave transformed back, but I'm realizing that there really are a lot of application where actual numbers will be useful in a program. It really doesn't make sense to convert from seconds to 0 to 1 and then back to seconds.

Like I said, you're doing something I haven't with custom Arduino nodes yet. These nodes pretty much just insert regular Arduino code into the compiled Embrio code, but with the wrapping of triggers and update events and such it's certainly possible that you're doing something right and Embrio is doing it wrong. If you find something please let me know so I can fix it. And of course if you figure out how to get it working please post it here for the record.

Dear Friends

I am writing a C code for K-medoids (K-Mean) clustering in Linux and compiling this code on GCC compiler. Found following error by compiler
