3.1 Prerequisites

µPad uses the RIOT operating system to satisfy its real-time constraints. Therefore, before building µPad, the RIOT source must be installed. Instructions for downloading and installing RIOT are outside the scope of this manual. RIOT does not maintain a stable interface, but µPad is known to work with the following commit:

commit fc4fd6222fc5ca0bb843dc2bb0e7e55335138802
Author: José Ignacio Alamos <jialamos@uc.cl>
Date:   Thu Jun 1 11:48:23 2017 -0400

    pkg/openthread: Add tests

Later commits will probably also work. You will also need to install the tool-chain corresponding to your chosen controller board. For details refer to the RIOT website http://www.riot-os.org.

Other requirements are

• The GNU Readline library (see https://www.gnu.org/software/readline) is needed for µPad’s non-interactive mode (see Making the most of the interactive mode).
• (optionally) the binutils (see https://www.gnu.org/software/binutils) built for the target(s) you wish to program. If you don’t have this, then you won’t be able to use a bounce buffer and you won’t be able to disassemble code on the target.

You must install all of the software mentioned above before attempting to build or install µPad.
