Web Camera

/media/uploads/1050186/camera3.jpg
When you click the "Web camera" in the menu screen, the pictures of a camera is indicated. It can be changed at a slider bar in "Wait time" at the timing of a renewal of a camera picture. (Defaults are 500ms.)

Setting by I2C

/media/uploads/1050186/setting_i2c3.jpg
When you click the "Setting by I2C" of the menu screen, the control screen of the device connected to the I2C bus is indicated. By sending a command of a format listed below("Format of the device set by I2C") in Direct input or File reference, data transmission and reception is possible with respect to devices connected to I2C_SDA and I2C_SCL terminals of I2C. The communication log of transmission and reception by "Format of the device set by I2C" is displayed in the log window. When you press the "Clear" button, the log is cleared. When you press the "Save" button, the log is saved.

Format of the device set by I2C

Method:I2C addr,data length,data1,data2,data3,...

The details of each parameter is shown below.
For specific settings, check on the specifications of the connected device, you must create a command along the format.

MethodPlease specify one of the following:
"Wr" ・・・ Write functions in I2C
"Rd" ・・・ Read functions in I2C
"WrNoP" ・・・ Write functions in I2C(No STOP condition)
"RdNoP" ・・・ Read functions in I2C(No STOP condition)
I2C addrSet the I2C address of device in hexadecimal.
Ex: If the address is 0x90, set the "90"
data lengthIf Method is "Wr" or "WrNoP", set write size(the size of the data portion) in hexadecimal.
Ex: If the write size is 2 byte(data1, data2), set the "02".
If Method is "Rd" or "RdNoP", set read size in hexadecimal.
Ex: If the read size is 10 byte, set the "0A".
dataIf Method is "Wr" or "WrNoP", set write data in 1 byte unit in hexadecimal.
Ex: If the write data is 0x01 0x02, set "01" in the data1 and "02" in the data2.
If Method is "Rd" or "RdNoP", this parameter is omitted.

An example of the format is shown below.

Wr:90,03,25,45,14

To the device of the I2C address 0x90, the data write of 3Byte(0x25 0x45 0x14)

Rd:90,02

To the device of the I2C address 0x90, the data read of 2Byte

LED On/Off

/media/uploads/1050186/led2.jpg
When you click the "LED On/Off" of the menu screen, the LED control screen is indicated. Each switch switches of GR-Boards to ON or OFF. Each switch indicates the current LED state. When the LED is On, the color of switch will change the LED color.

Switch to web page in SD card

Web pages displayed on the Web browser are located in the built-in ROM. file_table_peach.h is saved as table information for GR-PEACH and file_table_lychee.h is saved as table information for GR-LYCHEE. The contents of the saved file are as follows.

When connecting the SD card, SDBlockDevice will be displayed on the terminal and the web page displayed in the web browser will switch from the built-in ROM to the SD card. The top page is index.htm.

Change network connection

You can change the network connection by changing the following macro in main.cpp.

/**** User Selection *********/
#define NETWORK_TYPE           (2)                 /* Select  0(Ethernet), 1(BP3595), 2(ESP32 STA) ,3(ESP32 AP) */
#if (NETWORK_TYPE >= 1)
  #define SCAN_NETWORK         (1)                 /* Select  0(Use WLAN_SSID, WLAN_PSK, WLAN_SECURITY) or 1(To select a network using the terminal.) */
  #define WLAN_SSID            ("SSIDofYourAP")    /* SSID */
  #define WLAN_PSK             ("PSKofYourAP")     /* PSK(Pre-Shared Key) */
  #define WLAN_SECURITY        NSAPI_SECURITY_WPA_WPA2 /* NSAPI_SECURITY_NONE, NSAPI_SECURITY_WEP, NSAPI_SECURITY_WPA, NSAPI_SECURITY_WPA2 or NSAPI_SECURITY_WPA_WPA2 */
#endif

Depending on the value set for NETWORK_TYPE, the connection method changes as follows.

NumberConnectionDescription
0EthernetGR-PEACH only
1reservedIt can not be selected.
2ESP32 STAUse ESP32 in STA mode.
3ESP32 APUse ESP32 in AP mode.

When using GR-LYCHEE, NETWORK_TYPE 2 and 3 can be selected.
GR-PEACH Wireless CAMERA Shield is required separately when using ESP32 with GR-PEACH.

When using Ethernet, the user must provide the MAC address.
To specify MAC address, add fllowing function to main.cpp.

Specify MAC address

// set mac address
void mbed_mac_address(char *mac) {
    mac[0] = 0x00;
    mac[1] = 0x02;
    mac[2] = 0xF7;
    mac[3] = 0xF0;
    mac[4] = 0x00;
    mac[5] = 0x00;
}

Camera selection

To select the Camera, add camera-type to mbed_app.json.
See here for details.

mbed_app.json

{
    "config": {
        "camera":{
            "help": "0:disable 1:enable",

メニュー画面の"Setting by I2C"をクリックすると、I2Cバスに繋がっているデバイスの制御画面が表示されます。直接入力(Direct input)欄又はファイル参照(File reference)欄にて、下記("I2Cによるデバイス設定のフォーマット")に記載されているフォーマットのコマンドを送信する事で、I2CのI2C_SDA,I2C_SCL端子に繋がっているデバイスに対して、データの送受信が可能です。"I2Cによるデバイス設定のフォーマット"による送受信の通信ログは、ログウィンドウに表示されます。"Clear"ボタンを押すとログのクリア、"Save"ボタンを押すとログの保存ができます。

I2Cによるデバイス設定のフォーマット

Method:I2C addr,data length,data1,data2,data3,...

各パラメータの詳細を以下に示します。
具体的な設定値については、接続先のデバイスの仕様をご確認のうえ、フォーマットに沿ってコマンドを作成して下さい。

Method以下のいづれかを指定して下さい
"Wr" ・・・ I2Cでの書き込み
"Rd" ・・・ I2Cでの読み出し
"WrNoP" ・・・ I2Cでの書き込み(STOPコンディション省略)
"RdNoP" ・・・ I2Cでの読み出し(STOPコンディション省略)
I2C addr接続先デバイスのI2Cアドレスを16進数で設定して下さい。
(例) アドレスが0x90の場合、"90"を設定
data lengthMethodが"Wr"又は"WrNoP"の場合、書き込むサイズ(data部分のサイズ)を16進数で設定して下さい。
(例) 書き込むサイズが2Byte(data1,data2)の場合、"02"を設定
Methodが"Rd"又は"RdNoP"の場合は読み取るサイズを16進数で設定して下さい。
(例) 読み取りサイズが10Byteの場合、"0A"を設定
dataMethodが"Wr"又は"WrNoP"の場合、書き込むデータを16進数で1Byte単位で設定して下さい。
(例) 書き込みデータが0x01,0x02の場合、data1に"01"、data2に"02"を設定
"Rd"又は"RdNoP"の場合は省略して下さい。

フォーマットの例を以下に示します。

Wr:90,03,25,45,14

I2Cアドレス0x90のデバイスに対して0x25 0x45 0x14の計3Byteのデータ書き込み

Rd:90,02

I2Cアドレス0x90のデバイスに対して2Byteのデータ読み出し

LED On/Off 画面

/media/uploads/1050186/led2.jpg
メニュー画面の"LED On/Off"をクリックすると、LED操作画面が表示されます。各スイッチはGR-BoardのLED ON/OFFを切り替えます。スイッチはそれぞれGR-BoardのLEDの現在の状態を表しており、ONにすると対応するLEDの色になります。

SDカード内のWebページに切り替える

Webブラウザで表示されるWebページは内蔵ROMに配置されています。file_table_peach.h はGR-PEACH用、 file_table_lychee.h はGR-LYCHEE用のWebページがテーブル情報として保存されています。保存されているファイルの内容は下記の通りです。

SDカードを接続するとTerminal上に SDBlockDevice と表示され、Webブラウザで表示されるWebページが内蔵ROMからSDカードに切り替わります。トップページは index.htm となります。

ネットワークの接続方法を変更する

main.cppの下記マクロを変更することでネットワークの接続方法を変更できます。

/**** User Selection *********/
#define NETWORK_TYPE           (2)                 /* Select  0(Ethernet), 1(BP3595), 2(ESP32 STA) ,3(ESP32 AP) */
#if (NETWORK_TYPE >= 1)
  #define SCAN_NETWORK         (1)                 /* Select  0(Use WLAN_SSID, WLAN_PSK, WLAN_SECURITY) or 1(To select a network using the terminal.) */
  #define WLAN_SSID            ("SSIDofYourAP")    /* SSID */
  #define WLAN_PSK             ("PSKofYourAP")     /* PSK(Pre-Shared Key) */
  #define WLAN_SECURITY        NSAPI_SECURITY_WPA_WPA2 /* NSAPI_SECURITY_NONE, NSAPI_SECURITY_WEP, NSAPI_SECURITY_WPA, NSAPI_SECURITY_WPA2 or NSAPI_SECURITY_WPA_WPA2 */
#endif

NETWORK_TYPE に設定する値により、以下の接続方法に切り替わります。

番号接続方法説明
0EthernetGR-PEACHのみ。
1reserved選択できません。
2ESP32 STAESP32をSTAモードで使用します。
3ESP32 APESP32をAPモードで使用します。

GR-LYCHEEを使用する場合はNETWORK_TYPE 2と3が選択できます。
GR-PEACHでNETWORK_TYPE 2と3を使用する場合は別途GR-PEACH Wireless/Cameraシールドが必要です。

NETWORK_TYPE 1のEthernetを使う場合はMACアドレスをユーザが用意する必要があります。
"main.cpp"の最後にの下記のように関数を追加し、用意したMACアドレスを設定してください。

Specify MAC address

// set mac address
void mbed_mac_address(char *mac) {
    mac[0] = 0x00;
    mac[1] = 0x02;
    mac[2] = 0xF7;
    mac[3] = 0xF0;
    mac[4] = 0x00;
    mac[5] = 0x00;
}

カメラの設定

カメラの指定を行う場合はmbed_app.jsonにcamera-typeを変更して追加してください。
詳細はこちらを参照ください。
