well a 10 meter USB cable is well not good change over to a Ethernet board

Hi,

Great job, Thanks fellas,
So is it possible to have axis output (STEP/DIR) on arduino mega output ? for example port 0 pin 24 for X DIR and port 0 pin 25 for STEP ? so we can have a modbus breakout ?

Thanks

Awesome job! Just thought i would let you know I got this installed on a Teensy 3.2 and have used the USB for the interface. The goal is to use this as a pendant.

i have all this working with uccnc as well as mach3 now.
great stuff!

I tride a mega and also a uno both new.
What am i  doing wrong??? please help

hi! I need help from experts!

How to setup dro info on lcd connected to arduino modbus slave from link and library in 1.post???

Ihave included wire.h and liquidcristali2c.h for lcd in arduino code.
From now I ned help for how to send data from mach3 -->>>brain-->>serial modbus plugin--->>>arduino modbus slave ??
many users have this done but no documentation on arduino code, no info about serial plugin configs,

Hello. I ask you for help. I have a board arduino uno. I'm trying to flash it in the instructions, but it does not work.Gives an error message:

 -Arduino: 1.6.3 (Windows XP), Board: "Arduino Uno"
Build options changed, rebuilding all
CRC16.cpp:16:22: fatal error: WProgram.h: No such file or directory
 #include "WProgram.h"
compilation terminated.
Error compiling.
  This report would have more information with
  "Show verbose output during compilation"
  enabled in File > Preferences.

Tell me please what am I doing wrong?
Sorry for my English. Thank you in advance

I have been trying to make Shilling's code work for arduino due without success; the sketch uploaded successfully and the serial led's blinking, but no input/outputs responses between master slave.  On Uno the code works fine.  Has anyone tried to use arduino due with this code?  What could make it not working for due?

CRC16.cpp:16:22: fatal error: WProgram.h: No such file or directory

Bolded should be changed with Arduino.h if you use newer version of compiler.

Has there been any further developments on this?
