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® MbedTM enabled development platforms. You can also sketch like Arduino with the Renesas web compiler and IDE for GR.
Equipped with an Arm Cortex-A RZ/A1LU (R7S721030VCFP). Various Arduino shields can be mounted, but 3.3V I/F. The camera is attached as standard. Arduino shield connector, USB host interface connector is not mounted, parts are attached in -FULL version.
On the backside are a camera interface, an SD socket and a general-purpose LCD expansion connector is mounted.

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 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);
}
}
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. For details on how to use FlashAir, refer to the FlashAir Developers site.
Products whose operation have been confirmed are as follows.
Note: For W-04, the iSDIO function by CMD 17/24 can be used with firmware W 4.00.01 or later.
