Sample correction for crate(Rust library) to control Raspberry Pi
SPI is disabled when Raspberry pi is in default configration.
For enabling SPI, you need run raspi-config or add dtparam=spi=on to /boot/config.txt in root permission, and reboot.
The Following figure indicate circuit for crate samples.
Each crate sample is in "Sample" directory. These sample worked in Rust 1.27.0. Supported functions in each crate listed following table.
| rppal | rustpi_io | sysfs_gpio | wiring_pi | |
|---|---|---|---|---|
| GPIO | 〇 | △ | △ | 〇 |
| SPI | 〇 | 〇 | - | - |
〇: Supported and the function don't need root permission.
△: Supported but the function need root permission.
-: Not supported.
