Hello,
When I try to create a new Flowcode program for the RP 2040, I get the following error message:
PICO Compiler Toolchain is not installed.
1. I can work with pico-sdk in VS Code.
2. Flowcode Toolchain is installed.
3. The folder for pico-sdk is entered in the global settings.

Hi
This link details installation of toolchains
https://www.flowcode.co.uk/wiki/index.p ... Toolchains
At the bottom you will see further links to install ESP and Pico toolchains.
It is very important that you follow the guides exactly as documented. If you change directories or install different versions from the documentation then you will most likely face issues.
Once installed, remember to set your Com Port under Project Options too, so FC knows which PC port you are using.
Hope this helps.

Hello.
The Toolchain is not installed is caused by not adding the correct path within File > Global Options ... > Location tab
Check the path for PICO is correct.

Hello,
I installed the missing tools according to these instructions
https://www.flowcode.co.uk/wiki/index.p ... Toolchains
The path was automatically added by Flowcode
RPI Toolchain is installed under ...\pico_sdk
