In the above scenario, the new library will generate a blocking SPI transaction, thus allowing the first main loop SPI transfer to complete, before attempting the second transfer.

In fact, transaction support in the Arduino library is something [Paul] worked on himself, and gets around the problem of having SPI-related code happening in both the main loop of a program and ...

Wie kann man ein Flipdot-Display betreiben, das keinen I²C-Controller besitzt? Ein Arduino entschlüsselt die Kommunikation und übernimmt die Ansteuerung der Pixel.
