Patch the Arduino SPI library, true 16 bit transfers and add loop-friendly API This repo provides a version of the SPI libarary for the Arduio UNO R4, which uses the Renesas RA4M1 processor.

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 ...

Hello, on an Arduino Uno i succesfully realized a MCP2515 Shield running perfectly. Now i am using a ESP8266 with the following SPI Devices: 1x IL9341 TFT, 1x 74HC595 Expander (4x74HC595) and an ...
