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, ...

The Arduino sketch (arduino_file_transfer.ino) reads a file from an SD card and sends its contents to a Python server over Ethernet. It uses the Ethernet and SPI libraries to establish a connection ...

For the last several weeks, [Paul] has been working on a new Arduino SPI library ... generate a blocking SPI transaction, thus allowing the first main loop SPI transfer to complete, before ...

The best part is that the flexibility of the CPLD allowed [Eric] to devise an addressing system that takes advantage of unused bits in the Arduino’s SPI data transfer functions. When using a ...

SPI.transfer(primaryConfig); // send read byte command byte firstByte ... As can be seen, the RDATA command is sent, followed by 3 empty byte commands when the Arduino reads the DOUT line (not shown ...

I am trying to get an Arduino Uno kit to communicate with an MSP4302012 using SPI, but I am having some difficulties ... The Arduino will act as the master and transfer 1 byte per loop. Here's the ...
