UART-Replicate problems

[gcabral]

Hi there,

I am an authentic rookie. I know!
I don’t know how to program ++ C.
I really like XOD because it has the potential available to make it much easier for enthusiasts like me who are not in this area.

I try to follow the examples and tutorials I find to understand and apply XOD.

Today I tried to follow the example of serial communication between 2 Arduinos:
https://xod.io/docs/guide/uart-led-control/

However I have encountered difficulties such as this error that I do not understand. I followed all the steps. Mute plate and the result is the same …

According to what I understand there is a problem with a library

C: \ Users \ gcabr \ Documents \ XOD \ __ packages __ \ packages \ arduino \ hardware \ avr \ 1.8.1 \ libraries \ SoftwareSerial

I am trying to communicate with 2 Arduino Uno boards

Can anyone give a brief explanation of how to proceed and identify / eliminate these types of problems?

You need to scroll back to see what the first error is in the output to determine what is wrong.

Hi there. I got the same problem. The list of issues is below. So it seems the “parse-tabular
gabbapeople/uart-led-control/parse-tabular” has some problems.
Splits the incoming string line into parts depending on delimiter character. Outputs the specified part of string line

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 is a problem with the parse-tabular node. The name of the output in code (output_PRT) doesn’t match the name of the output pin (OUT). Easily fixed by changing the name of the output pin from OUT to PRT.

Great!!! Thanks a lot!!! It works now. You are my hero now, Dear Wayland!

@wayland, @talyanninza
Thx for pointing out the error. I fixed it and updated the library.
