Hardware connection for SPI samples

spi_bitbang (samples/drivers/spi_bitbang): Loopback for MISO and MOSI

• Note: The purpose of testing sample spi_bitbang on RA boards is to provide users with an understanding of the RA SPI driver. To test this sample using the SPI hardware IP, you can configure it by adding the overlay and configuration files with the following content:

  samples/drivers/spi_bitbang/boards/mck_ra8t1.conf

  CONFIG_STDOUT_CONSOLE=y
  CONFIG_SPI=y
  CONFIG_SPI_B_INTERRUPT=y
  CONFIG_SPI_B_RA_DTC=y
  CONFIG_LOG=y
  CONFIG_SPI_BITBANG=n
  

  • Note: We have to disable the CONFIG_SPI_BITBANG since we use SPI hardware IP to test spi_bitbang.

  samples/drivers/spi_bitbang/boards/mck_ra8t1.overlay

   spibb0: &spi0 {
  	rx-dtc;
  	tx-dtc;
  	cs-gpios = <&ioport2 4 GPIO_ACTIVE_LOW>;
  	status = "okay";
  };
  
  &ioport2 {
  	status = "okay";
  };
