For many devices, standard SPI settings might not work. Use SPISettings to configure:

The library is pre-installed with the Arduino IDE, covering all main Arduino platforms (AVR, MEGA, SAMD, SAM). To use it, simply include it at the top of your sketch: #include Use code with caution. Key Library Functions

If communication fails, reduce the clock speed, as some devices cannot handle high frequencies.

Please provide more context or paste the content of the file if it’s a custom header.

For sending data from the controller to the peripheral.

The SPI library uses a set of standardized functions to manage communication:
