Hello,
I've just watched the very useful FLOWCODE 8 VLOG 1: SIMULATING C CODE.
In it Daniel mentions the fact that FLOWCODE functions can be used in C; for example the Delay function FCI_DELAYBYTE_S(x).
Is there a list of these somewhere?
Also instructions like SET_PORT() and GET_PORT() have changed since the V6 / Hi Tech version. I can't find them in the XC8 users guide. Where can I find these please?
Thanks,
Dave

Hello Dave,

I'm glad to hear you enjoyed the video. There are two answers depending on if you want to simulate these C code function calls, or just be able to type them out yourself with the intention of compiling to chip.

The bit of background info I'll give here may or may not be useful to you.

Flowcode has many functions that it uses in the generated C code, created as a result of the various operations you may invoke from within the flowchart. If you take a look at the current macro's C code with "Show as C code", you can see the results of adding various macro call icons, calculations etc.

In the past, when you run the Flowcode simulator, it was actually simulating only the flowchart itself, rather than the generated C code. The new C simulator attempts to parse the final C code directly, and then simulate the effects: this is what allows you to type out your own C code and have it be simulated.

Regarding the list of Flowcode-generated functions that you can type out in the C code yourself, and then simulate: there is a list here on the wiki page, with some other details.

Currently not all Flowcode-generated functions can be parsed by the C simulator, (some of the code generated by Flowcode can often be quite complex) but hopefully the critical ones (user macro calls, set/get port values and delays) will be useful to you. The plan is to make the C simulator understand more Flowcode-generated functions in the future.

For other Flowcode-generated functions that you may wish to type out yourself in the C code, which can still be compiled to chip (but not simulated when typed directly in the C code): these can be seen by:

1) Creating a Calculation icon and adding a call to the specific built-in function you want (accessed by the two right-most columns in the Calculation icon editor) and then:
2) Viewing the generated C code with "Show as C code".

If you replicate the syntax used when typing your own C code, then the results should compile to your microcontroller without problems.

I hope this has helped.

Daniel.

Thanks for the comprehensive reply Daniel. Previously we had set_bit and clear_bit. How would you set say, INTCON,5?
