In this tutorial, we will create an Arduino sketch that demonstrates the reception and visualization of byte-by-byte serial data using LEDs. The objective of this project is to show how serial data ...

Discussion on resolving the issue of converting volatile uint32_t to PortReq for Arduino Zero in Pixel speed test.

Eight digital outputs act as the parallel interface. When a byte is received over serial, the individual bits are set on the individual digital lines connected to the printer’s parallel port.
