Saleae Serial Peripheral Interface (SPI) Analyzer

Getting Started

MacOS

Dependencies:

• XCode with command line tools
• CMake 3.13+

Installing command line tools after XCode is installed:

xcode-select --install

Then open XCode, open Preferences from the main menu, go to locations, and select the only option under 'Command line tools'.

Installing CMake on MacOS:

1. Download the binary distribution for MacOS, cmake-*-Darwin-x86_64.dmg
2. Install the usual way by dragging into applications.
3. Open a terminal and run the following:

/Applications/CMake.app/Contents/bin/cmake-gui --install

Note: Errors may occur if older versions of CMake are installed.

Building the analyzer:

mkdir build
cd build
cmake ..
cmake --build .

Ubuntu 16.04

Dependencies:

• CMake 3.13+
• gcc 4.8+

Misc dependencies:

sudo apt-get install build-essential

Building the analyzer:

mkdir build
cd build
cmake ..
cmake --build .

Windows

Dependencies:

• Visual Studio 2015 Update 3
• CMake 3.13+

Visual Studio 2015

Note - newer versions of Visual Studio should be fine.
