add Arduino UNO R4 MINIMA to boards.h please

[ckosse]

Hi,

I am new to this and would love to use Firmata with the Arduino UNO R4 MINIMA. Unfortunately, I don't know how to update boards.h accordingly. Any help would be appreciated :)

Thanks!

I'm new too and face the same problem for the R4 Wifi. Any help or guidance to solve this issue would be highly appreciated! 🙏🏼

Support for the Uno R4 has been added to ConfigurableFirmata. It will be included in the next release (due as soon as I find time)

did you have time to add support for standard firmata?

Thanks

[pgrawehr]

@speccy88 No, and I think I won't do it. StandardFirmata is good for very old boards with very limited amount of memory. But for anything larger than an Uno R3, I see no advantage in using and supporting StandardFirmata.

@speccy88 I'm happy to do it. If you will provide me with a pointer as to what is missing, then I'll be happy to add it in.

I don't personally have an R4, so I haven't had anything to test it on.

@zfields Here's the change for ConfigurableFirmata. The required update for StandardFirmata should be equivalent.

I have no such board either, but I installed the matching toolbox and it appears to compile.

@speccy88 Will you please try the uno-r4 branch, and confirm it works on your hardware.
#509

I have confirmed that it compiles for both the Uno R4 Minima and Wi-Fi boards, but I do not have hardware to validate it against.

Is there any plan to add support for the new Arduino R4 WIFI to StandardFirmataWifi in the future?

[pgrawehr]

@rvroessel See the comment of zfields above. He has implemented it on a branch, but is waiting for confirmation from somebody that has the hardware.

I have tested StandardFirmataPlus on the R4 WiFi, and it seems to work well. Thank you for this. I cannot get StandardFirmataWifi to work, because there is no support for UNO R4 WiFi yet.

[pgrawehr]

Ok, understood. Yea, that requires somebody to write the Wifi support code for the R4 Wifi, it seems.

Note that because the number of active mainainers here is very limited, I'm focussing support for new boards on ConfigurableFirmata instead. All the newer boards have enough memory to support the customizable approach.

If someone could add this, that would be super helpful.

Current Error from Arduino IDE when trying to upload the StandardFirmata:

In file included from /Users/jules/Documents/Arduino/libraries/Firmata/Firmata.h:17:0,

  ^~~~~
exit status 1

Compilation error: exit status 1

From the following link.

Suggestion is to add the following content to boards.h:

#elif defined(ARDUINO_UNOWIFIR4)
#define TOTAL_ANALOG_PINS 6
#define TOTAL_PINS 20 // 14 digital + 6 analog
#define VERSION_BLINK_PIN 13 // or any available pin for LED
#define IS_PIN_DIGITAL(p) ((p) >= 0 && (p) <= 13) // Adjusted for digital pins
#define IS_PIN_ANALOG(p) ((p) >= 14 && (p) <= 19) // Adjusted for analog pins
#define IS_PIN_PWM(p) (((p) == 3) || ((p) >= 5 && (p) <= 9) || ((p) >= 10 && (p) <= 13)) // Adjusted for PWM pins
#define IS_PIN_SERVO(p) (((p) == 3) || ((p) >= 5 && (p) <= 9) || ((p) >= 10 && (p) <= 13)) // Adjusted for servo pins
#define IS_PIN_I2C(p) ((p) == 18 || (p) == 19) // Adjusted for I2C pins
#define IS_PIN_SPI(p) ((p) == SS || (p) == MOSI || (p) == MISO || (p) == SCK) // Adjusted for SPI pins
#define PIN_TO_DIGITAL(p) (p) // Adjusted for digital pins
#define PIN_TO_ANALOG(p) ((p)-14) // Adjusted for analog pins
#define PIN_TO_PWM(p) PIN_TO_DIGITAL(p) // Adjusted for PWM pins
#define PIN_TO_SERVO(p) PIN_TO_DIGITAL(p)

But doing so returns:

Compilation error: 'TOTAL_PORTS' was not declared in this scope

I tried to include a #define TOTAL_PORTS using 3 and 1 to the boards.h but that did not work.

Also the Firmata library from the Arduino IDE 2.5.9 differs from the Github 2.5.9 version. specifically the boards.h file and the readme.

Thank you for the help :)

It seems there are some compilation problems due to compiler updates. Shouldn't be difficult to fix.
