So, which firmware have you used to obtain 4089744 bytes (3993.9 ...

Re: RAM, native, viper and assembler

From a quick test native, viper and inline assembler all work out of the box. IMHO, this is a very strong point of Pyboard D : initial MicroPython release with mature implementation. Only few MicroPython boards support native and viper decorator, less yet assembler decorator. Counting the days to b...

There are different models of Pyboard D with less/more RAM ???
There are certainly two as I have them. I don't know how many variants are planned.
How can we identify these 2 models ? Different names on top of the microcontroller ?

The free RAM depends on the model. I have one with about 470K free. From a quick test native, viper and inline assembler all work out of the box.
Thanks for the information.
Wow, a lot better than approx. 100KB of Pyboard v1.1.

Re: pinout for the Colour LCD skin LCD160CRv1.0H

In my tests, the 3V3 pin on the bottom connector of LCD160CR should be avoided. GND, SDA, SCL, etc, work ok.
