ESP32

Hi! How can I compile ESP32 in FC10? I downloaded ESP toolchain, but I don't have a license, how can I get one?
Thanks!

Oh, and one more thing, I downloaded FC11 to try it, but it won't let me do anything, no matter what I try, it tells me that I don't have the required license...

And PPS: Under what conditions is it free? Thank you!

So, how can I compile esp32 in FC 10?

[Steve-Matrix]

If you run Flowcode (v10 or v11) then the "ESP32" and "ESP32_WROOM_32" targets are available to use without purchasing the ESP chip-pack.

You will also need to have the ESP toolchain installed.

As I said above, I installed the toolchain for esp32, but the compiler message is that I do not have a valid license to compile.

Hello.
Steve stated:

The target device you selected is WROVER which neither of the target devices Steve stated, so its not free, hence the licence message.

You will need to change your device from ESP32_WROVER to either ESP or ESP32_WROOM_32

I can't compile, where am I going wrong?

This is the compiler message:

I have just tried to compile using a licence without the ESP chip-pack and it all seems to be working as expected. The free "ESP32" and "ESP32_WROOM_32" targets are allowed to compile but others are not.

I have tried this in both v10 and v11.

I don't know why it is failing for you. Perhaps the FCD (chip definition file) for the target has been modified by you or is not up-to-date - you can check this by ensuring all library files are current.

When you try to compile in v11, you will get 2 files generated with the extensions "msg.txt" and "fcxlog.txt". Can you please attach these files here so I can have a look. Please attach the unmodified files themselves rather that adding modified text to a post. If you would rather keep them secret, please send them to me via PM.

Hello.
I have spotted an issue, looking at the ESP toolchain path.
The ESP32 Toolchain should default to C:\FC_ESP
Your location is C:\Program Files (x86)\Flowcode\Common\Compilers\
Which is correct for all other toolchains except for ESP32
I would advise to check your C drive and see where the FC_ESP directory is stored.
If it is not C:\FC_ESP (or whatever your default drive is), then uninstall the toolchain and reinstall making sure the path is C:\FC_ESP.

If the default path is correct
Then within Flowcode select File > Global Settings... > Locations tab
Make sure ESP: is showing C:\FC_ESP\\ (or whatever your default drive is)
If not change it to the correct path.
