Add support for Arduino UNO WiFi

[Vincent-Pang]

Hi, please add support for Arduino UNO WiFi.

I am doing some development on this board with CLion. And I would like to use the Arduino WiFi Link Library.

I found that there are some unowifi related code on platformio github (at the end of boards.txt) already, but I can't found unowifi at board manager. Then I install the most similar board uno instead.

The followings are my steps.

pio init --ide clion --board uno pio lib install "WiFi Link"

main.cpp

#include <Arduino.h>
#include <WiFiLink.h>

void setup()
{
    Serial.begin(9600);

    //Check if communication with the wifi module has been established
    if (WiFi.status() == WL_NO_WIFI_MODULE_COMM)
    {
        Serial.println(F("Communication with WiFi module not established."));
        while (true) // don't continue:
        {
        }
    }

}

void loop()
{
}

When I build it, compile error occur.

Compiling .pioenvs/uno/lib/WiFi Link_ID1541/utility/comm.o
Compiling .pioenvs/uno/lib/WiFi Link_ID1541/utility/server_drv.o
In file included from .piolibdeps/WiFi Link_ID1541/src/utility/comm.cpp:27:0:
.piolibdeps/WiFi Link_ID1541/src/utility/comm.h:40:8: error: 'CommDrv' does not name a type
extern CommDrv commDrv;
^

Then I took a look at comm.h. And from this src code, I think I should define ESP_CH_UART first (for Arduino UNO WIFI DEV. EDITION) although I know I should not modify this file by myself. But anyway, let me try if it could work.

#ifndef COMM_H
#define COMM_H

//#if defined(__AVR_ATmega32U4__) || defined(ARDUINO_ARCH_STM32F4)
#if defined(ESP_CH_UART)            // <---- I have to define this
    #include "utility/uart/uart_drv.h"
    class CommDrv : public UartDrv {};
#elif defined(ESP_CH_SPI)              
    #include "utility/spi/spi_drv.h"
    class CommDrv : public SpiDrv {};
#endif

extern CommDrv commDrv;

#endif

So I define it manually.

#ifndef COMM_H
#define COMM_H

#define ESP_CH_UART    // <---- I define it manually

//#if defined(__AVR_ATmega32U4__) || defined(ARDUINO_ARCH_STM32F4)
#if defined(ESP_CH_UART)
    #include "utility/uart/uart_drv.h"
    class CommDrv : public UartDrv {};
#elif defined(ESP_CH_SPI)
    #include "utility/spi/spi_drv.h"
    class CommDrv : public SpiDrv {};
#endif

extern CommDrv commDrv;

#endif

And then there is another compile error. Cannot find Wire.h

Compiling .pioenvs/uno/src/main.o
Compiling .pioenvs/uno/lib/WiFi Link_ID1541/utility/uart/SC16IS750.o
.piolibdeps/WiFi Link_ID1541/src/utility/uart/SC16IS750.cpp:25:18: fatal error: Wire.h: No such file or directory
#include <Wire.h>
^
compilation terminated.

I don't know why it can't find Wire.h. Never mind, let me include it manually.

#include <Arduino.h>
#include <Wire.h>   // <---- I include it manually
#include <WiFiLink.h>

void setup() {...}
void loop() {...}

Linking error occur this time. I have no idea how to fix it ...

Please help to support Arduino UNO WiFi in a proper way. Thanks.

I am having the same problem here!please any one to help

[anton-mir]

Plz add it

I don't see much need for this as the Original Uno Wifi is dead, and we already have support for its successor, the Arduino UNO Wifi Rev2, which is supported by PlatformIO.
