... 4999986Hz :-)

It is pretty much all in C - I used a custom interrupt for the timer1 overflow - to reduce the overhead (overflows is defined in supplementary code) - needed to create a dummy macro to keep FC happy (dummy - is never called)

The 1s (d3) interrupt uses the standard FC setup - but most ...

... I mark the end of the data by having a 'duplicate' prefix length if 7 (0b111)

On an esp32 - memory isn't a problem - I put the data array into supplementary code (on smaller MCUs it would probably be necessary to save as an array in flash memory - and use a smaller word list)

The encoder outputs to ...

... the file specified (or clicks 'refresh'?)

There also seems to be a limit on the LUT size of about 4600 bytes - and these are laid out in a more logical manner (multiple rows)

I worked around by generating the C source and adding to supplementary code - although a #include might be neater?

... If the Pico is running FreeRTOS as the 'OS' - would it be possible to use FreeRTOS functions - such as xTaskCreate - in FC (using C blocks / supplementary code) as on the esp32?
There are several examples for the esp32 on the forums - using such features as tasks / queues etc - and it might be ...

I commented out a couple of the #includes in supplementary code - you'll probably need to re-enable....

... you can use the C to initialise - rename (app_main) initialise (or some such) and add a function definition to the 'includes' (top) box of supplementary code... ( void initialise(void); ) Remove the loop (and the 'hello world'?) from the end of the function...

Then call initialise(); from a C ...

... component for you.

Using an Arduino library directly in Flowcode at the moment without some form of conversion is likely to fail due to C / C++ incompatibilities. An AI agent would be very good at turning an Arduino C++ library into pure C code you can include from the supplementary code window.

Further to @chipfryer27's suggestion, there is more info about the Supplementary Code feature in the wiki and there are many posts on the forum that discuss it too. For example, see here:

Hi

In Project Options, within the Other Options section you have a checkbox to Use Supplementary Code. If you tick tihis you can then specify a library to include.

Regards

External code can be included in Supplementary Code. See: https://www.flowcode.co.uk/wiki/index.php?title=Supplementary_Code

Instead of adding the code directly to Flowcode, add statements into Supplementary Code such as the following to point it at external files:

#include "C:\MyFolder\MyCode.h ...
