C Code Generator and Pic Microcontroller

[dan07]

Hello everyone,

I found couple threads discussion on how to use C Code Generator from LabVIEW to create code that could be compiled to HEX and programmed into Pic Microcontrollers.

However, it seems that no one had sucessfully achieved that. I believe that assignig IO, config header and oscillator frequency should be challenging.

Does anyone could provide me any information on how to proceed to achieve that? I wrote a simple VI and converted it to C using the C Code Generator, but I have no idea what I have to adjust into C code in order to have it working on my Pic Microcontroller.

Thanks,

Dan07.

Hi Dan07, 

I see no one has commented on this for a few days so I'll throw my 2 cents in. The limited experience I have with the c code generator is pretty much to not use it. LabVIEW does a lot of things for you that would result in a runtime error for C code. An example of this is accessing an array outside of it's index, normally this will give you a runtime error in C,whereas, LabVIEW will just return a zero. 

I found there's a lot of that going on in the background so going through the code to try and extract your algorithms or changing specific parts can be really challenging. Personally, I'd get a cRIO to run LabVIEW programs natively or just write your code in C to begin with.

There are a few tutorials to get you started with the C code generator. Linked below, I guess if you have to go down that route they'll be your best starting points?

Sorry I can't really help with this one 😕

Thanks
