   MPLAB Tools Ecosystem  Downloading an MCC Melody Example Project   

So you want to create a new project or work on an existing project using the MPLAB® Code Configurator (MCC) Melody graphical programming environment, but which software development tools do you need? Where do you get them and how do you install them?

MCC Melody comes pre-installed as a plug-in in the MPLAB X Integrated Development Environment (IDE) as of version 6.10. All you need to install is the MPLAB X IDE and the MPLAB XC8 or XC-DSC C compiler, both are free and can be downloaded from the Microchip website.

Download and Install MPLAB X IDE

When you get to the MPLAB X IDE webpage, you’ll find the download button near the top of the page. Clicking this takes you further down the page to a section that allows you to select the download for your operating system. Start downloading and installing the MPLAB X IDE by clicking Download. Select a download location on your computer and wait for it to complete.

Select Applications allows the selection of applications and device support to install. More selections mean more installation time and more hard drive space.

MPLAB Integrated Programming Environment (IPE) is not required for this course, so uncheck this box. If you want to install this later, rerun the MPLAB X IDE installer. The only device support for MCC is 8-bit MCUs and 16-bit dsPIC® Digital Signal Controllers (DSCs). If you also want to work on 32-bit MCUs, leave its corresponding box checked and click Next >.

The Setup Wizard shows that it’s ready to start the installation process. Click Next > and wait for installation to complete.
