Compilation Error - Sending Text to a PC From Arduino

jmwright · May 7, 2019, 11:30am

I’d like to send data over the USB-serial interface from an Arduino Uno/Nano to my PC. I found the uart-usb block and implemented what I thought would print over USB to the PC, but I got an error.

Here is the error I get.

/tmp/xod_temp_sketchbookh5AAy6/xod_1557227707999_sketch/xod_1557227707999_sketch.ino:1806:22: error: request for member 'begin' in '* state->xod::xod__uart__uart_usb::State::uart', which is of non-class type 'int'
         state->uart->begin();
                      ^

Error: exit status 1

The generated C++ code contains errors. It can be due to a bad node implementation or if your board is not compatible with XOD runtime code. The original compiler error message is above. Fix C++ errors to continue. If you believe it is a bug, report the problem to XOD developers.

There’s more to the stack trace, but I didn’t want to flood this post with the whole trace. I can post it if needed. I’m so new to XOD I don’t know if my patch is even close to right, and the only examples I’ve found online are for serial communication between two Arduinos. I’m running version 0.29.1 of the XOD IDE.

After Compiling sketch..., there are some first lines of code that marks the error, is that?

I have tried and I have no error, but I can not send data, the truth is that I have not used Uart

Your mistake starts here.

I think it uses Linux, in W10, I do not have that error.

Change tweak-string-16 by constant-string or just put “,” in concat, to see if the error disappears.

@cesars Thanks for the help. Your suggestion eliminated that tweak error, but more still remain. I forgot to mention that I’m on Ubuntu 18.04.

The generated C++ code contains errors. It can be due to a bad node implementation or if your board is not compatible with XOD runtime code. The original compiler error message is above. Fix C++ errors to continue. If you believe it is a bug, report the problem to XOD developers.

I just noticed that if I replace the uart-usb block with the uart block, I don’t get an error.

cesars · May 7, 2019, 5:23pm

Ups, I was testing in UART, I thought you had renamed it, I also have the error with UART-USB

jmwright · May 7, 2019, 5:43pm

Ok, interesting. It happens in Windows too then. I wonder if I should open an issue on GitHub.

cesars · May 7, 2019, 8:21pm

yes, i think this is an issue

jmwright · May 8, 2019, 9:36pm

I submitted an issue on GitHub for this: https://github.com/xodio/xod/issues/1775

Yeah, this is so misguiding that it should be considered a bug.

The uart-usb node represents a USB serial on the boards having a dedicated CDC interface (like Leonardo or Micro). For Uno and Nano the interface is shared with UART #0. So, if you would use uart-0 instead of uart-usb, all should work fine for you.
