DRI0029 Veyron servo driver serial port
Grey.CC 2015-06-10 01:41:52 3616 Views6 Replies Hello
i have a big problem with the control module "Veyron Servo Driver (24 Channel)" by combining TX1 / dfrobot and TX2 / RX2, if you are using usb everything works. If you want to control the device through other ports (communication with ardiuno for instructions), the control is not working.
Do I need to somehow change the control of the usb on the TX1 / 2 to get it working ??

Finally i figured out that DIP (A,B,SERIAL) was broken. I have replace it and now I'm able to communicate with board using TTL pins. However for some reason only 2400 and 115200 baud rates are supported. Also baud rates to A/B switch position mapping is not correct comparing to documentation.
In my case
A0, B1 - 115200
A0, B0 - 2400
A1, B0 - N/A
A1, B1 - N/A
Also I have noticed that board might not work if blue LED is always ON. In normal mode it should blink several times and then it should turn off. oleg.v.lytvynenko

I have same issue. USB connection works fine but when connecting using SERIAL pins the board does not respond.
Tried different baudrates swithces. Seems like firmware does not support TTL mode.
Any fix? oleg.v.lytvynenko

sorry to awake this old post.
I also got this problem and I already tried to poke the baud switch till I'm afraid to broke the switch. But it doesn't seem to fix the problem.
Is there any other solution? barotoardi

Probably it's for the baud rate setting. Have you noticed the baudrate setting switch on the corner of the board. Is it in the right place, e.g. if your code is 115200, then the 3 switchs should be in the position as:A1, B1, SERIAL. Besides, the switch are not good to use, you might need a little strenth to poke it from one side to the other side to make sure it is connected firmly. Wendy.Hu

Wendy.Hu 2017-01-29 06:43:36 hai grey, i'm using the veyron GUI it's works normal but i have an issue using arduino
i already use your recommendation but still can't control the driver via arduino. I already following every step of the tutorial including the sample program and the cabling to the arduino.
i see the rx2 of the driver is blinking and i guess it receive the data from arduino.
Please Help!! mahr.botb

mahr.botb 2015-06-10 01:44:54 How do connect the module? Please check common GND connection cable (Black cable):
Generally it is caused by this issue. Grey.CC
