Hi! Thanks for the like!
Drop me a note if you want to give it a try. Letters from Germany to Spain are cheap...

It's certainly an interesting project, but I'm afraid that I can't help much here. The only programmer I ever made was USBASP based and my main contribution was reviving an old version of AVR-GCC. I'm the STM8 guy :-)

OMG!!! Now I see I have messed up posts 😅😅😅 How embarrasing!! Yeah, yesterday I was taking a look at your eForth project for Stm8. I already have a W1209 thermostat with an STM8S003F3P6 on it and last year i programmed some minimum board of the 103F3 with cosmic compiler (i did a disco light controller 🤣) . I'm fascinated with your project, and your domain of the low level architecture of STM8 core. I'll keep an eye from time to time and meanwhile i'll be getting along with the eForth language (it's kinda different than others).

Thanks for your reply. 

No problem at all! At least I had a closer look at the FX2LP board and found one for 3.92 incl. shipping - that's a very good price for a "makeshift 3.3V 16 bit logic analyzer".

eForth is a bit weird, but in my opinion learning new ways of solving things is always rewarding in unexpected ways :-)

By the way, making a disco-light-controller with STM8 eForth should be really easy :-D
