Author: meera_hussien

Creation date:

Evaluation Type: Development Boards & Tools

Did you receive all parts the manufacturer stated would be included in the package?: True

What other parts do you consider comparable to this product?: This product is comparable to the previous product which is RX65N

What were the biggest problems encountered?: The biggest problem which i encountered is with the IDE because the IDE has an evaluation period. Previously i have installed it in my station. To resolve the issue, i have to install the IDE in another station.

Renesas RX72N Envision Kit - Review

By Hussien

 

 

Introduction

 

RX72N Envision Kit features the RX72N MCU which is the flagship of the 32-bit microcontroller RX family. This kit includes a WQVGA LCD with a capacitive touch panel. This allows for GUI development using an LCD controller and a 2D drawing engine. The RX72N Envision Kit also provides a D2Audio IC with a stereo MEMS microphone to support HMI features like voice input and output. The kits also come with communication support for Fi/BLE and ethernet. Moreover, the extended can be utilized using Macronix's 3222Mb serial flash with USB and microSD slots.

Unboxing

 

Now let's look at the unboxing video

 

 

Running RX72N Out Of The Box

 

The RX72N Envision Kit comes preloaded with SPORTS GAMES. To run this program, plug the micro USB into the ECN1 of envision kit. Below is the demonstration video.

Software Setup

 

In order to program the RX72N, we need to install the Renesas e2studio IDE. This can be downloaded here. The installation is a straightforward process. Once done with the installation, the next step is to download and install the RX Family C/C++ Compiler Package. All this can be done through the guided installation process. Below is the snapshot of the installation process arranged in order.

Those are basically the steps for the software installation. Once done, the next is to run the sample program. The following video illustrates steps to make a simple GUI

Below is the video of a sample GUI from emwin

 

 

 

Hardware Setup

 

For the hardware setup, there is no much to be done since the kit is ready to plug and play.

 

 

Home Automation System

 

My plan for this road test is to make a simple automation system. But somehow I am facing some difficulties to get the GUI running. Currently, i am still working on it to resolve the issue.

 

Conclusion


       In the nutshell, RX72N Envision Kit is a very interesting kit to explore the world of IoT. In my opinion, there is a lot of applications that can be build using the kit. The only fallback which I would say is that the example or help provided are very minimal apart from the vast documentation. It would be very helpful if there is a simple example that shows the process of utilizing all the functions that are available on the kit. Another thing to take note of is, to get familiarised with the e2 studio requires some time as well. I think this is a usual process when exploring a new development board. I would also like to thank Renesas and Element14, for giving me the opportunity to learn and explore Renesas RX72N Envision Kit, through this roadtest.
