I have added an example to use API's interactively
Meanwhile, there are mecrisp stellaris in version 2.4.9.
For the listed PSOC's the FORTH version 2.4.1 to 2.4.5 are available, depending on the PSOC type. An upgrade to 2.4.9 is not required.
is it possible to porting mecrisp-stellaris for my own board with a PSOC 5LP (Cy8C5888axi)?
Yes it is possible in principle. To check this, I need detailed information. Contact me by e-mail. You will find the e-mail address in every download
