+===== 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
+<code bash>
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+</code>
+  *reboot to activate rust
+  *
