GR-LYCHEE

Gadget Renesas Board for the RZ/A2M MPUs, pin-compatible with Arduino UNO

概览

GR-LYCHEE is an IoT prototyping board with a camera and wireless capability (Wi-Fi, Bluetooth Low Energy (BLE)). It is the Gadget Renesas reference board for the Renesas RZ/A1LU group of microprocessors (MPUs). GR-LYCHEE is pin-compatible with Arduino UNO and Arm® Mbed™ enabled development platforms. You can also sketch like Arduino with the Renesas web compiler and IDE for GR.

Technical Information

Board Distributors

GR-LYCHEE boards and other shields can be purchased through the following sites:

  • Enables getting a VGA (640 x 480) image with attached camera. When transferring with USB CDC, a transfer rate of 60fps can be realized.
  • OpenCV v3.2 is applied and various SDKs are provided. Computer vision can be enjoyed right away.
  • Equipped with ESP32. Cloud connection with Wi-Fi, smartphone communication with BLE possible.
  • Equipped with a 4-pole audio jack. Audio input/output is possible.
  • SD card can be inserted. FlashAir™ is also OK. (More about FlashAir Connection can be found on the Resources tab.)
  • Mbed™ easy programming. If you copy it to storage, you can run it.
  • Optional USB A connector can be equipped. Can be used for connection of USB memory etc.

How to Program

Project File for e2 studio

Project file for sketching in Eclipse-based development environment e2 studio. For downloading and installing e2 studio, please refer to the e2 studio product page.

You can import as an archive file (zip) as an existing workspace from the e2 studio menu "File" -> "Import".

Do the menu "Project" -> "Update all dependencies" at the initial build. Only sources changed since the next build will be compiled.

DisplayApp

DisplayApp is an application that displays the camera image sent by USB CDC.

Installing the USB driver is required on versions earlier than Windows 10.

Below is an Arduino-like sketch example.

        #include <Arduino.h>
                #include <Camera.h>
                #include "DisplayApp.h"
                Camera camera;
                static DisplayApp display_app;
                void setup() {
                    camera.begin();
                }
                 
                void loop() {
                    display_app.SendJpeg(camera.getJpegAdr(), (int)camera.createJpeg());
                    delay(10);
                }
                }

About FlashAirTM Connection

You can connect FlashAir to the SD socket on the back of GR-LYCHEE. You can access photos saved with GR-LYCHEE's camera from your smartphone or tablet. It can also be used as a Wi-Fi interface using iSDIO.

Products whose operation have been confirmed are as follows.

  • FlashAir W-03 (8GB, 16GB, 32GB)
  • FlashAir W-04 (16GB, 32GB)

Note: For W-04, the iSDIO function by CMD 17/24 can be used with firmware W 4.00.01 or later.

3D Data for Fusion 360

3D data that can be imported with Autodesk Fusion 360. Use it when making cases for GR-LYCHEE.
