A Rust-flavoured Pololu Mini Maestro API Interface

Written and developed by UBC Bionics, Ltd.

Getting Started

The Rust crate "rppal" provides user-level APIs for protocols such as PWM, I2C, and UART. In order to configure UART for the Raspberry Pi, do the following:

  1. Remove "console=serial0,11520" from /boot/cmdline.txt
  2. Disable the Bluetooth by:
    • Adding "dtoverlay=pi3-disable-bt" to /boot/config.txt (without the quotation marks)
      • For the RPi4 models, add "dtoverlay=disable-bt" instead
      • Once this is done, reboot the Pi (by powering it off and then on again)
      • Connecting GPIO Pin-14 (physical pin 08) to an LED, this LED should be LIT
    • Running the command "sudo systemctl disable hciuart"

Trouble-shooting

If "cargo build" or "cargo test" do not work because of the rppal dependency, check the rppal documentations on how to set up UART. The link is here.
