Starting with hardware, the Arduino Mega is based on the Atmega2560 microcontroller. In the iteration that is found on the Mega board, the microcontroller comes in a standard TQFP 100-pin package.

This copy of grbl-mega is a working prototype used to send binary spindle information (speed + direction) using the hardware SPI interface to another slave board that will take care of spindle control ...

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 ...
