RX72N Envision Kit Advantages over the Other Platform Product.

 

  • Large WQVGA LCD with a capacitive touch panel.
  • On-Board Emulator.
  • On-Board Wi-Fi/ BLE communications Using EPS32-WROOM2-32D
  • Two stereo MEMS microphones to support voice input for HMI.
  • Multiple GUI Development Options (emWin, Aeropoint GUI).

 

Detailed Review:


Renesas RX72N Envision kit is Specifically designed for HMI and IoT applications. for HMI application Capacitive Touch panel and Audio Input and outputs is the perfect combo in this board. Developing a Graphical user interface using Aeropoint GUI minimizes the GUI firmware development, This feature helps the firmware developer to concentrate on the other Hardware features. Onboard emulators help to debug easily. Secured WIFI-BLE communications using Onboard ESP32 helps to create Internet of things applications. The large capacitive touch panel will give more space to integrate better GUI. The power management system provides continuous power distribution with less thermal generation

 

A Simple Example Program Creating using e2 Studio.

 

You can easily start with The RX72N Envision Kit By following the below steps.

 

1. Download and Install The e2 studio from the official website of Renesashttps://www.renesas.com/us/en/software-tool/e-studio. To know how to install the e2 studio please go through the linkhttps://www.renesas.com/us/en/software-tool/e-studio.

 

2. Download and Install C/C++ Compiler Package for RX Family by followinghttps://www.renesas.com/us/en/software-tool/cc-compiler-package-rx-family.

 

Note: If you do not install the Compiler package errors will appear as Follows.

 

E0511175:Neither isa nor cpu is specified.

make: *** [src/smc_gen/general/r_smc_interrupt.obj] Error 1
src/smc_gen/general/subdir.mk:26: recipe for target 'src/smc_gen/general/r_smc_interrupt.obj' failed
"make -j4 all" terminated with exit code 2. Build might be incomplete.

 

3. After Successful Installation Of e2 studio Open The e2 studio. After a few seconds Workspace Window will pop up Here we need to give a name to Workspace. I have given the Workspace Name as an Example. After entering the workspace name Enter launch.

 

4. Go to file  Select C/C++ Project.

 

5. Then Select  Renesas CC RX C/C++ Executable Project and click Next.

 

6. Give a Project Name

 

7. Select Toolchain version V3.02

8. Select Target Board As Envision RX72N

 

9. Select Hardware Debug Configuration as E2 Lite RX and Click Next.

10. Select use Smart Configurator and Select Finish.

 

Smart Configuration window will Pop-up

 

 

11. Click On the Board and check the right board is selected.

 

12. Now Make clock configuration settings from clocks. in the PLL Circuit select Frequency Multiplication as 15. In PPLL Circuit select Frequency Division as 1/2 and Click on Generate Code and Enter Proceed.

 

13. Code will be generated and automatically updated to the Main File.

14. Now we need to add the required software components to The main file click on Components and Click On the Plus Symbol to add the Component.

 

15. Select Simple CMT Driver for Creating Time tick and Click On Generate Code.

 

16. Select Ports From software component configuration and click Finish.

 

17. In Port Selection select PORT4 and From Port4 Select P40 as OUT And OUTPUT1  And Generate Code.

 

17. Now we need to add the main code here I am creating a LED Blinking Example. To write the code to blink the LED we need to open ".C " From src folder.

 

 

 

I am using Bare Metal code Example Code From Renesas Git.https://github.com/renesas/rx72n-envision-kit/wiki/Generate-new-project-%28bare-metal%29

 

18.  I will copy the code and save the file and I am going to  Build the project.

If the code doesn't contain any error it will display the Zero errors window.

 

 

 

 

 

19. In order to upload the code, we have to set Debug configuration. To make the settings Go to Run Tab and select Debug Configuration, From the Debugger Tab make The Main clock Source as Extal. Extal Frequency As 16 Mhz, Connection Type as Fine, Power Target From The Emulator as NO, And Click Apply.

 

 

 

20. Now Connect The Device to the PC Via USB Cable and Set the emulator selection switch SW1 As shown in the Below Image.

 

21. Click on Launch in Debug Mode, The software starts to upload the code to the  RX72N.  When the perspective switch window pop-ups select  Switch status of uploading code is displayed as Finished Download.

 

 

22. To Run The Code On the RX72N ENVISION KIT Press The PLAY/Resume Tab. If the device is successful The status will be displayed As Running
