Added arduino support

Added Arduino support to the v2 sdk

[tcpipchip]

hi @jacobjuneau6
I compiled your SDK (with git checkout to update) , but is not creating the COMM port to Arduino, only USBNCM

[tcpipchip]

After solve that COMM "issue", we have this "issue" too

hi @jacobjuneau6
We see that Serial3 and Serial2 are the same serial...can you modify the img to us ?
#define PIN_UART2_TX (6)
#define PIN_UART2_RX (7)
#define PIN_UART3_TX (6)
#define PIN_UART3_RX (7)

If i modify to
#define PIN_UART2_TX (6)
#define PIN_UART2_RX (7)
#define PIN_UART3_TX (4)
#define PIN_UART3_RX (5)

No difference to UART3...i tested with this code...

void setup() {
// put your setup code here, to run once:
Serial3.begin(57600);
}

void loop() {
// put your main code here, to run repeatedly:
Serial3.println("Data from UART3");
delay(5000);
}

But no output on pin 4 of the DUO 256

Can you fix the problem ?

[jacobjuneau6]

I have fixed the problem with it not running the COM script. Pull the latest changes and check. I will look into the pin numbering issue later as I do not have my board with me.

[jacobjuneau6]

Can you verify where the burnd file is on the filesystem?

Hi @jacobjuneau6
i will do that tomorrow! Now i am in the classroom!
thank you :)

what do you mean ?

[tcpipchip]

Btw, look our project to DUO 256 programming :)
Only drag components to programming :)

Thank you again to see the Arduino UART2/UART3

[tcpipchip]

Hi @jacobjuneau6
I am back :)
I burnt the Branch!

Good news:
Now i can see the COMx

Bad news:
I can't upload more the Arduino Code, no communication

After your fix that, i have other issue, that happens if you use your Arduino SDK IMG with Duo USB&Ethernet IOB
https://milkv.io/docs/duo/io-board/usb-ethernet-iob

Thank you!

Btw, i have time to make the tests :)

[jacobjuneau6]

Can you check where the file burnd is when the system is on.

[jacobjuneau6]

Try sshing into the board and running the burnd program manually, then try arduino.

[tcpipchip]

Success :)

[tcpipchip]

to the Duo non 256 version, the 4 and 5 are correct...but not tested here (variant)

[tcpipchip]

Solved the UART issue

@carbonfix Some changes may not be suitable for normal images, should we move this to a new branch(like v1 SDK, Arduino branch)

[shiptux]

I think using burnd source code is better than a binary file.

[tcpipchip]

where is exactly the Burnd source code ?

[shiptux]

where is exactly the Burnd source code ?

I am not sure how jacobjuneau6 compiles it.

[jacobjuneau6]

The burnd file is precompiled I pulled it from the v1 SDK.

[jacobjuneau6]

It is pre-compiled in the v1 sdk.

[tcpipchip]

Then there is no open-source code to it ?

[jacobjuneau6]

No. In the v1 sdk it is a binary.

[tcpipchip]

after 40 days tryng, got success

Hi,
New updated VISUINO with UART FIX to MILK-V Duo256
https://www.visuino.com/installs/Visuino_Pro_8_0_0_129_Beta2.zip

[tcpipchip]

Hi, can you add this to the MILK-V doc ?
https://github.com/tcpipchip/milkv.io/blob/main/docs/duo/getting-started/VISUINO.md
And the link to ?

[carbonfix]

@jacobjuneau6 @tcpipchip Thank you very much for your work! Due to some other issues we are currently dealing with in the SDK, this submission has not been verified and used in Visuino in time. We will address these issues as soon as possible. Thanks again for your work, it is excellent!

[tcpipchip]

@carbonfix @jacobjuneau6
We have to thanks you to publish the issue. Visuino will help a lot the MILK-V DUO and MILK-V DUO 256, and when ported the Arduino SDK to MILK-V Duo S. The users can do a lot of complex stuff with VISUINO easy easy :) Access to thousand of libraries. When have time, fell free to test.
@jacobjuneau6 see when we can have the Arduino SDK to DuoS running :)
Thanks too the my friend Boian Mitov too, i presented him about Milk-v and he ported to VISUINO :)
