Arcpi / Ezbpi On Raspberry Pi 3 Errors

Hello,

I am trying to run ARCPi and EZBPi on a Raspberry Pi 3. I have tried installing them on two different versions of Raspbian, the latest release and the 11/13/18 (stretch) version, which was released closer to "DJ's 9th Live Hack" (I have been following that YouTube tutorial). When I execute ARCPi, I get the following error before ARC launches:


pi@raspberrypi:~/EZ-BuilderPi $ mono ARC.exe
Unknown heap type: #GUlD

Unknown heap type: #Blop

Unknown heap type: #GUlD

Unknown heap type: #Blop

The help viewer could not load. Maybe you don't have chmsee installed or haven't set MONO_HELP_VIEWER. The specific error message was: ApplicationName='chmsee', CommandLine='"https://synthiam.com/Software"';, CurrentDirectory='', Native error= Cannot find the specified file

Once ARC launches, if I try to open a previously saved project, a window pops up with a similar message:

I searched Synthiam Community for a similar thread, so forgive me if this issue has been addressed in a previous post and I missed it. I am happy to answer any questions. Does anyone know what I could have done wrong during the installation?

Thanks Tim

You don't have one ? What kind of controller do you use to configure (Dynamixel Wizard 2.0) the servos ?

#58  

I use an OpenCM9.04 board plugged into an OpenCM 485 Expansion Board.

#59  

Does the the EZ-B IoTiny support Dynamixel servos? It says that it does here, but when I try to add/use the Dynamixel plugin in ARC (while connected to the EZ-B IoTiny), I receive the following error:

I am still not able to operate Dynamixel servos using the TX/RX pins on the Raspberry Pi, so I decided to try using an EZ-B IoTiny to test the Dynamixel servos. That way, I would know that I have the correct baud rate, servo ID's, etc. before further troubleshooting the direct Raspberry Pi/EZ-BuilderPi route.

hi robo

did you take the wright one?the one in pic give no error.

Yes, I believe so. Thank you for taking the time to test the Dynamixel plugin. Was ARC connected to an EZ-B IoTiny while adding the Dynamixel plugin? That is when I receive the error. When not connected, I am able to add the plugin without an error.

i used the io tiny.i have no dynamixels .it opened without an error.

#63  

Thank you, I will try reinstalling ARC and the Dynamixel plugin.

#64  

I tried reinstalling ARC, the Dynamixel plugin and I updated the firmware for the EZ-B IoTiny board, but I am still not able to use the Dynamixel plugin while connected to the EZ-B IoTiny. I received the same error (from the screenshot attached to post #59).

So I disconnected the EZ-B IoTiny from ARC and once again tried adding the Dynamixel plugin. This time, I did not receive an error from adding the Dynamixel plugin (with the EZ-B IoTiny disconnected). I then tried connecting to the EZ-B IoTiny, but was not able to (I received an error message). I added Debug so that you could see what is causing the error:

Just to confirm the source of my connection issue, I removed the Dynamixel plugin, and was then able to connect to the EZ-B IoTiny:

Any thoughts?
