Arduino_GFX utilize Arduino Built-in SPI class to support 8-bit SPI for most platform. Most tiny display in hobbiest electronics world support 8-bit SPI. But some requires 9-bit SPI. Arduino_GFX ...

To prevent data corruption when using multiple SPI devices on the same bus, care must be taken to ensure that they are only accessed from within the main loop, or from the interrupt routine, never ...

This repo provides a version of the SPI libarary for the Arduio UNO R4, which uses the Renesas RA4M1 processor. In the standard distribution, 16 bit transfers are done as back to back byte transfers, ...

Quick, how do you wire up an SPI bus between a microcontroller and a peripheral? SCK goes to SCK, MISO goes to MISO, and MOSI goes to MOSI, right? Yeah. You’ll need to throw in a chip select pin, but ...
