How do I enable and use SPI on UP Boards?
To enable SPI on UP Boards, you need to install specific ACPI overrides since SPI devices are not enabled by default in user space. After downloading and installing the appropriate overrides, you can find the SPI devices under /dev/spi*. For instance, you might see /dev/spidev0.0 and /dev/spidev0.1. These devices can be accessed using standard Linux tools or libraries like spidev for Python.
