Title: The Pico RP2040 Mandlebrot challenge!
Post by: techman-001 on February 26, 2021, 10:29:13 am
Can you beat Matthias's Mandlebrot binary of 252 Bytes ?

See this URL for the details and complete project including the Assembly source.

Well, there is an assembly source, but no Forth source code to be seen? Isn't mecrisp stuff meant to be Forth?
I would have been curious to take a look at the Forth code for this.

The Mecrisp-Stellaris architect wrote the Mandlebrot challenge in Assembly as his aim was minimal binary size.

Mecrisp-Stellaris is 100% Assembly itself and its users are conversant in both languages.

Worth squirreling away for the H/W setup code alone... (which is about 2/3rds of the projects ~300 lines).

Plus the toolset is all GPL'd, (like everything Mecrisp*).

New Release @ 1 March 2021.

Prints a Mandlebrot to a serial terminal and has a breathing LED effect while waiting for keypress, all in a 252 Byte binary!

Also includes a lot of extra information including emulator, fully commented assembly source and proof of concept files.

New Release @ 4 Mar 2021.

Now with Mandlebrot and Tricorn Set plus a breathing LED cosine effect while waiting for keypress.

 Still in a 252 Bytes binary executable for the Pico.
