I'm very glad that your company has new products on the market, especially the increase of small steering gear. I'm very excited,

However, an abnormal phenomenon occurred when we tested a small steering gear (xc330-t288-t), We use example / proctol2 of Dynamix SDK o / bulk_ Read_ Write. C program tests two steering gears (xc330-t288-t) to control the lights and control positions respectively, but they are stuck. What do you think is the reason?

Thank you again

Hi,

Have you modified the control table address definitions in the example code for the XC330?

The default example is written for PRO series which will not work for XC330.

For example,

#define ADDR_PRO_TORQUE_ENABLE          64                 // Control table address is different in Dynamixel model
#define ADDR_PRO_LED_RED                65
#define ADDR_PRO_GOAL_POSITION          116
#define ADDR_PRO_PRESENT_POSITION       132

Also, the Min, Max position value should be adjusted for XC330.

#define DXL_MINIMUM_POSITION_VALUE      0             // Dynamixel will rotate between this value
#define DXL_MAXIMUM_POSITION_VALUE      4095              // and this value (note that the Dynamixel would not move when the position value is out of movable range. Check e-manual about the range of the Dynamixel you use.)

Please refer to the eManual below to find out the Control Table information and the valid range of value.

Hello

Yes, you're right. We did find this parameter wrong at the beginning. This also gives you a suggestion. The SDK can form different folders according to different steering gears.

However, the solution you mentioned is not the problem. If you take a closer look at the screenshot I sent, it is normal when we test other demos (such as ping readwrite), except bulk_ There is a bug in readwrite. I suggest you try it yourself?

Thank you again
