

<bank>: 0 = 8‐15,2 = Channel Channel Channel 0‐7,1 = 16‐23.



<value>: decimal output (0‐255), Bit0 = LSB.

This command allows the 8-bit binary write-once and simultaneously update all channels in the

bank, the update will be completed within 20ms after receive carriage return symbols

Example Commmand

# 1:123 <cr>

This command enables bank output 123 in decimalism, 123(decimal) = 01111011 (binary), bank

1 for channels 8-15, then channel 8 and 13 in bank 1 will be 0, the other channel will be 1.

Q <cr>

If servo is rotating, it will return "+", if servo has moved to a specific location, it will return "."

The return value of this command will delay 50us to 5ms.

QP <ch> <cr>



<ch>: Servo channel number, 0 ‐ 23.

The return value is one byte (binary), which means the servo current pulse width, resolution:

10us, for example, the pulse width is 1500us, then it will return to 150 (binary). This command

can query multiple servo pulse width, each servo has a byte, the return value will delay 50us to

5ms, typical value is 100us.

How to drive the board from the DFServo

We have made a special software--DFServo to drive Veyron.
