Hi !
I'm trying to call a very simple function from C ++ lib, writed for the
test.
function with prototype:
extern "C" float interpolationFunc(float* xm, float* ym, int size, float x).

FFIExamples class >> interpolationFunc_xm: xM ym: yM size: size x: x

Hi,
could be the problem that you are using the same external array for both
xm and ym?.
The clone message just creates a shallow copy of the external array.
It does not allocates a new external array, it only copies the address in
both xm and ym.
You should better do something like this:
xm
Thank, i'm trued do this, and i'm got
aBoxedFloat64 4.5879913020458836e-41 ,
which is still a very strange value

So, you're putting 2 at index 2 of xm, and then writing 3 past end of array,
and in ym yo

Nevermind me, hadn't had my coffee yet, for some reason I didn't see it was
doWithIndex: you were using :/
Still a bit scary that FFIExternalArray at:put: doesn't perform bounds
checks...

I have been unsuccessful in using an Arduino board with Pharo 6.1(32bit) and
the Firmata package.
The board is an Arduino Uno clone (ELEGOO UNO R3). The board appears to work
fine with the Arduino IDE, which was tested with the BLINK program. The
Standard Firmata Library appears to have been

this with a Pharo GUI that displays sentences one at a time and permit choice
of tags using radio buttons. The results need to be saved as a CS
