Hi all

Just a quick heads up if you have one of the new CM-530 controllers:

The current [ CM-530 ] firmware (version 1.1969) has a noticeably long latency in switching between TX and RX on the Dynamixel bus. So a response packet from HaViMo gets corrupt.

A work around is available and can be obtained here http://www.havimo.com/?p=130

This limitation applies to Calibration only.
In implementation mode (ie after being calibrated) the CM-530 behaves perfectly when using HAViMo 2.0

Therefore at the moment, and if you have a CM-530, you can calibrate in 2 modes:
- Using a USb2Dynamixel
- By installing the Calibration firmware for CM-530
(not to be confused with calibration firmwares for other controllers - which is not needed!!!!
with the current HaViMoGUI, HaViMo can be calibrated directly from all other Robotis controllers without needing a calibration firmware.
Only the CM-530 requires this calibration firmware, at this point).

For more information please see here http://www.havimo.com/?p=130 if you have a CM-530 and here http://www.havimo.com/?page_id=32 for all others (CM5/510/700/USB2Dynamixel)

Pedro.

Hi,

you just need to bridge GND and DATA lines on 3-pin connector. connect a 7.5-12 volt supply to VCC and GND pins of the 4 pin one, and use TXD and RXD for the communication.

Use 115200,8N1

Best regards,
Hamid.

Do you have a schematic for direct serial connection?

Thanks in advance

thanks Hamid! in this new version I can save and load the LUT. Only the "Read Lut" button is still not working with CM-510, hope you can fix this in the future
Thanks.

Luis.

Hi Luis, Hi Harry,

After several bug fixes (With special thanks to Harry for his feedback) the version 0.3 is online now.

I have also uploaded the following tutorial video on HaViMoGUI.

The only bug I am still busy with are the communication errors when reading or writing the LUT via CM5 or CM510. I hope I can also fix this in the next few days.

Best regards,
Hamid.

Thanks for answer Hamid.

Luis.

It's my understanding the Load and Save functions haven't been implemented yet while the Read function has some bugs. Hamid is addressing these issues and solutions are hopefully forthcoming soon.

Hi Luis,

before I can help you , I need to know which hardware setup you are using. Also give more details about which functions work and which don't.

Best regards,
Hamid.

Hi hamid, I bought an Havimo 2 camera a few days ago, I downloaded this HavimoGUI but I can't understand it very well. I hope you can tell me wich are the steps to achieve calibration.
Thanks in advance.
