トラブルシューティング
Troubleshoot BeagleBone Black SPI Interface
SPI bus 1 shares pins with HDMI, which is enabled by default. Use
showPins to view the current pin usage. If HDMI is enabled,
disable HDMI before using enableSPI to enable this bus. For
information on how to disable HDMI, see the BeagleBone Black hardware documentation.
注目の例
Analog Input Using SPI
Use the SPI peripheral on BeagleBone Black® hardware to connect to an MCP3008 10-bit 8-channel ADC.
