Some of it was my bad. I had missed the call to `main()` from my python script.

Then microbit spi modes aren't as documented.

Trying other modes i get a valid response, but it's not glitch free. Especially when blanking all pixels

If you look at the data stream with a logic analyzer you will most likely see that there are gaps between the bytes. Once a gap is longer than ~60┬Ás, it will be considered as a reset of the LED.
