Easy way to download individual EP and AP projects

RA Example Projects (EPs) and Application Projects (APs)  distributed from GitHub at https://github.com/renesas/ra-fsp-examples. 

EPs are simple projects that show how a given RA peripheral can be setup and used.  EPs are listed based on officially available Renesas HW kits.  Some of these are  Evaluation Kits (EKs), Fast Prototyping Boards (FPBs), and Motor Control Kits (MCKs).   

APs are more involved projects that may utilize several peripheral to provide a solution.  For example, cloud connectivity or low power applications for specific Renesas HW kits.    

You can download EP and AP bundes in zip form from the GitHub site in Releases page.  This will allow you to get all EPs and APs.  However, this is a very large file and you may be interested in a one EP on a given kit.  How do you download only the EP or AP you want or need?

You do with GitZip Web extension.  With GitZip extension:

  1. Select the files or the folders you want
  2. Click on Download
  3. Your selections will be in a zip file

GitZip extension is available for Chrome, MS Edge, and Firefox. And it is free at here: https://gitzip.org/

See an example below.  

Let's assume at you are working on a project with RA8D1.  You are interested in how ADC and AGT peripherals can be configured and used.  Then go to EK-RA8D1 EP folder and select ADC and AGT EPs.  Click on "Downloaded checked items".  Done!
