RX TX control via Microcontroller

[Timo Lenz]

Hello everybody, I would like to use the RX / TX pins around the Smartstepper, unfortunately nothing happens when I e.g. from the Arduino move 60 send. do you have to install other software or something like that before? have no experience with it yet. Please help Thank you very much Sincerely yours timo lenz

You need to turn on the serial port in the board.h 

Look for this in the board.h

//Define this to allow command out serial port, else hardware serial is debug log

//#define CMD_SERIAL_PORT

Then uncomment the #define so it is like this:

//Define this to allow command out serial port, else hardware serial is debug log

#define CMD_SERIAL_PORT

Thank you for the great and quick answers.

Could you possibly tell me where I can download the firmware?

However, I have a quick question for you again. When flashing the SmartStepper with Arduino, all Serial5.print and also other "commands / functions" are marked as errors. Do you know what I have to do?

Possibly as a hint. The following URL is required under Settings at Arduino:

https://github.com/Misfittech/arduino-board-index/raw/master/package_misfittech_index.json

however, an error message also occurs here.

Do you have an answer?

That would be really great

Many many thanks

Kind regards

Timo

(Thanks for the best support I have ever seen)

usually that problem is that correct board is not selected in Arduino

Can you tell what board must be used for compiling in Arduino IDE?
I tried the "zero" board SAMD21 but I get the same errors like described above, for example "serial5" not declared.

I bought a board from you and want to control the motor by serial RX/TX commands.
Unfortunately, you did not enable the serial port by default. You use it as debug port. But seriously: What does a user want to do with a debug port?
Wouldn't it be better to enable the command port by default?
A user (NOT a programming nerd) wants to control the motor, not debug functions or compile firmware.

So now I have the problem that I must recompile the firmware with serial port enabled.
But unfortunalely, Arduino gives errors.
Can you explain why Arduino gives error messages with the "serial5"?
Or could you compile a hex-file of the firmware with the serial command port enabled?

Thanks

Joachim

Please make sure you follow the instructions here:

http://misfittech.net/blog/arduino-package-install/ 

and that the board is the "nano zero" board.

Got it!
Thank you very very much. Sorry, but I don't use Arduino very often.
I don't like this confusing system with all the boards, drivers and libraries.

But the thing is running now.
Very nice support :-)
