There are two different wirings, this one is for hardware SPI. Another one is used for software SPI
Steps
- Installed raspbian
- Activated SPI in raspi-config
- wired a MCP3008 and a sharp IR module to the GPIO pins
- followed tuto on python but did not get data from module (read 0.00)
- rewired to software SPI (needs documenting)
- installed rust in tty with lightdm stopped
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
- reboot to activate rust
