METAtris

Hey @Riksu9000,

The game is great!
I have a little suggestion: I'd love to have the "hold" feature as found in other tetrises.

"Using the B button, you can store the current piece once and recall the previously held piece (if any)."

Cheers!

I will write down details and gives the code to Riksu9000 who wrote MetaTris

Great you managed to figure it out! It looks cool! ^.^

now I have to really understand SPI to write a minimal overview for an article :)

Once more, thanks for your help.

I read other threads around SPI and Gamebuino here and it looks like there is a need for a clear documentation on how to use hardware SPI.

It was not useful for me, 8x8 led matrix does not need high frequency

The library you use self-implements SPI. So that library won't really work with hardware SPI.

As for hardware SPI, just using the official SPI library is enough - no need to initialize it (SPI.begin, SPI.end) as it is already initialized
