Re: Porting MicroPython to the Pokitto device (based on NXP LPC11U68)

That's really cool! I'm impressed you were able to get it all working in what must be a limited RAM environment - how much memory do you have to work with on the Pokitto? My quick perusal of the datasheets for that family of processors suggests that it tops out at 256KB... Looking forward to seeing...

These are the attributes and methods: Rect.x Rect.y Rect.width Rect.height Rect.colliderect(Rect) #include <stdio.h> #include <string...

Re: Implementing Python class instance attributes with C ?

Thanks, but it looks a bit too complicated as an example. It would be great if you cared to tell me how should I change my Rect class?

Implementing Python class instance attributes with C ?

Hi, I have been porting MicroPython to Pokitto (http://www.pokitto.com) gaming device, which is based on LPC11U68 (NXP ARM Cortex-M0+), and it runs beautifully there :-) I am also porting a small subset of PyGame over MicroPython to be able to use Pokitto's color screen capabilities. In that I have ...
