Connecting Arduino to ARC
Customizing Firmware
The firmware can be modified and optimized for additional features. When the firmware is modified, the new capabilities must be registered with Synthiam website.
I should add a disclaimer that this tutorial is not complete. You can customize the EZ-Arduino firmware with new features (called capabilities) that ARC will recognize, although that part of this tutorial hasn't been completed yet.
Very interesting, hopefully this does not stop/limit any future hardware development like say a newer EZ-5 controller.
Wow, this is very interesting and as others have said a Game Changer!! This definitely opens up a ton of questions, but I’ll have a play around with this first.
Has anyone gotten it to work yet? I'm in need of some assistance please.
The only servo response I've been able to get is on "D0" of my UNO. No other pin combination responds. Even then, I seem to have wrong speed and position, as my small servo barely moves between 0-90 and only in one direction. Its also backwards in the "Servo Summary." Speed scroll moves position setting and position scroll moves speed setting. I'm guessing I have a few things set incorrectly or perhaps way off base. I'm green at this, so take it easy on me.
Whoops...Hello by the way! This is my first post and first time ever using ARC. I don't know about anything else here yet. I just downloaded it tonight and jumped in with my Arduino and servos. Sorry if this is the wrong place to ask questions, but I haven't found a user forum yet. thanks!
:DHey there, Welcome HuneyBee Glad you have jumped on trying ARC on your Arduino! I am very curious to see if anyone does get this working out!
I followed the "'Connecting Arduino to ARC" step by step and loaded the Arduino Uno firmware OK onto my Arduino Uno board.
But I get the following error message when attempting to Connect to the ARC.

Could it be I'm using a Arduino Uno+ board, rather then a standard Arduino Uno board? The boards should be identical apart from the Uno+ has more features regarding power pin-outs and USB.
Hunnybee: welcome! That’s interesting - what servo shield are you using? And are you powering the uno with a battery? It won’t run off usb. The ports D0 and D1 won't be used on the Arduino because they are reserved for DEBUG and USB communication on all Arduinos. So the firmware has the ports D0 and D1 ignored. The reason you may see servos on D0 or D1 move is due to the USB traffic. There's no way to control D0 or D1 from ARC because it's reserved for the USB on all Arduinos.
Something else to notice which is bizarre on the arduino servo shields is they seem to provide servo power from the voltage regulator, which means +5 volts. That's not very useful because most servos will brown-out the pcb.
Cem: you’re not using the beta ARC.
Thanks JD, Yep, I didn’t read all the requirements!!
ARC Version
Thanks everyone for the welcomes. Also thanks for updating the code. I uploaded the latest version. Now I have much more success than my first time around using the UNO. I am getting the servo responses I expect, though I still have a lot to figure out in general.
I started printing an INMOOV head as my first project, but I had to shelve it for a number of reasons. I haven't decided what else will be my first robotics project, but it will definitely be much smaller scope. I'm excited to learn about ARC. I hope to see you all around here somewhere. Thanks again!
