Matlab interfacing with Bioloid using USB2DYNAMIXEL

Hi Nandy
I just noticed something in your post.
What we at the mentioned project was use the Simulink Real-Time-PC-Target
This is a mode of Matlab/simulink that takes priority over most other things running in windows to the extent that standard windows COM interfaces are unreliable or unavailable.
Therefore I had to write driver level code to talk directly with the serial port chip (16550 compatible).

Therefore the FTDI COM emulation will probably not work for that code.

I suggest you find a PC that has a physical serial port on the motherboard.

Bioloid interfacing with matlabusnig USB2DXL

DEAR Khashi.E

Let you know the problem in details. I'm using a PC which have no serial port. This is why I'm using USB2DXL RS232 mode and connect it to CM5 with a serial cable. when I try to interface Matlab with Biloid using 'COMMUNICATION PROTOCOL BY RS232' then problem occurs. The link is given: http://humanoids.dem.ist.utl.pt/pc_rs232/overview.html

The above problem must occur who is using Laptop for doing Matab interfacing with Bioloid. Thank you for replying.

With regards
DEBASISH

Hi nandy,
You will try to fix simple problems first.then if it dousn't work,try with technical solutions.
check your PC COM3 port.perhaps it is damaged.try to connecting USB2DXL to another usb port.
change or reinstall your ax-12 frimware version if red LED of the ax-12 is always on.
check your USB2DXL is on TTL mode.

if this solutions douse not work,let me know.

regards

Hi !!!

I'm doing matlab interfacing with bioloid through COM PORT3 using USB2DYNAMIXEL. But the problem is that Model is downloaded, input is shown on the SCOPE. but their is no response of AX-12 servo. If I use COM PORT1 with out USB2DYNAMIXEL, their is no problem. Please give me some suggestion. where should I change in CMEX S-function.....
